Skill Types
Every skill belongs to one of four behavioral types. The type governs when and how a skill activates — not how powerful it is. A Passive skill at Novice tier is not weaker than an Active at Master; power scales with prerequisites, conditions, and Essence investment, not with activation type.
Passive
Always running. No activation required and no deliberate Essence expenditure per use. The skill maintains its effect continuously as long as the survivor holds it. Most foundational skills are Passive — they represent a permanent change to the survivor's baseline rather than an action they perform.
De-activation conditions. State and Verbal conditions on a Passive skill do not gate activation — they function as de-activation triggers. The skill runs continuously unless the specified state is violated or the oath is broken, at which point it suspends. When the condition is restored, the skill resumes. The slot remains occupied, the prerequisite chain is intact, and nothing cascades. The skill is waiting, not lost.
Active
Requires deliberate activation. The survivor chooses when to fire the skill and how much Essence to invest in the output. Most offensive and high-output skills are Active — the choice to use them is meaningful, and the Essence cost is paid at the moment of use.
Reactive
Activates automatically when a defined condition is met — no deliberate choice required in the moment. The survivor designs the trigger when enfixing the skill, but cannot prevent it from firing once that trigger is satisfied. High-value for defense and counterplay; unreliable as a pure offensive tool.
Hybrid
A combination of two or more activation modes. A Hybrid might maintain a Passive baseline while offering an Active escalation on demand — or trigger Reactively and then require Active direction of the resulting effect. The combination is part of the skill's condition structure and is established at enfixing.
Seal Skills
Seal Skills — Active locked open
A Seal Skill is an Active skill whose conditions have been permanently locked into an always-attempting-to-run state by deliberate survivor choice. Once sealed, it behaves like a Passive in practice — running continuously — but it bleeds Essence at an ongoing rate to maintain those open conditions. Sealing is irreversible. The survivor cannot return the skill to standard Active behavior.
The trade. A Seal converts Essence throughput into a static, always-available effect. The skill no longer needs to be activated — it is always on — but the ongoing Essence drain is real and accumulates over time. Survivors who Seal multiple skills must manage a permanent Essence budget that does not exist for those using standard Active skills.
Sealing requires conditions. The mechanism is placing conditions on an Active skill and locking them permanently open. A skill with no conditions cannot be sealed — there is nothing to lock. The more conditions the skill carries, the more significant the Essence cost of maintaining them all simultaneously.
A deliberate commitment. Survivors do not accidentally Seal skills. The process requires sustained self-imposed constraint — placing conditions on themselves consistently until the System recognizes the pattern. The Seal is what happens when that commitment is made permanent.
Output scales with the survivor. A Sealed skill's output is not frozen at the moment of sealing. It remains tied to the survivor's current stats and Essence pool, and grows as those grow. Sealing is a long-term investment — the effect compounds over a career rather than locking in a snapshot of who the survivor was when they committed.
The ceiling can be raised. Conditions can be added to a Sealed skill after sealing. Each addition raises the output ceiling further — and raises the ongoing Essence drain proportionally. This is the Sealed skill's evolution path: more conditions, more cost, more power.
State and Verbal conditions as de-activation triggers. Although a Sealed skill is always attempting to run, State and Verbal conditions placed on it function as circuit breakers rather than activation gates. The skill runs continuously unless the specified state is violated or the oath is broken — at which point it suspends. When the condition is restored, the skill resumes. This is not cascade collapse: the slot is still occupied, the prerequisite chain is intact, and the skill can return to full operation. It is a temporary suspension with a defined recovery path.
Oath as condition vs. oath as prerequisite. An oath that functions as a prerequisite for a Sealed skill is load-bearing — breaking it destroys the prerequisite and triggers immediate cascade collapse of the skill and everything built on it. An oath that functions as a de-activation condition works differently: breaking it suspends the skill rather than collapsing it. However, if the oath cannot be retaken — if the breaking is witnessed, System-registered, and final — the suspension becomes permanent. The skill remains in the slot, occupying it, Essence drain potentially still running, non-functional indefinitely. Permanent suspension is distinct from cascade loss: cascade frees the slot for rebuilding. Permanent suspension traps it.
Other conditions remain destroyable. Sealing does not protect a skill's non-State, non-Verbal conditions from external attack. A Relational condition on a Sealed skill collapses if the relationship is permanently severed. A Material condition collapses if the required object is destroyed. When these conditions collapse, the Seal falls with them — there is nothing left to be locked open. Sealed skills carry the same soft-target vulnerabilities as any conditioned skill; the irreversibility of the Seal does not extend to the conditions that hold it.
Skill Evolution
Skills evolve when the survivor pushes Essence past the skill's established output ceiling — into territory the System has no registered pattern for — and sustains that behavior consistently enough that the System is forced to acknowledge it. When the System formalizes the pattern, the skill upgrades: new conditions are written into its structure and the ceiling rises to match what the survivor was already doing. The survivor leads. The System patches. Evolution is the System playing catch-up.
The liminal state
Between the moment a survivor begins pushing past their skill's ceiling and the moment the System issues a formal upgrade, the skill enters a liminal state. The System does not announce this. There is no progress bar, no notification, no visible marker on the interface. The survivor must read the change themselves.
The skill leaks. A liminal skill begins doing things it does not normally do — exceeding its registered parameters, producing emergent effects that fall outside its documented behavior. These effects are real and sometimes powerful, but they are harder to control than the skill's normal output. The survivor is operating in territory the System has not yet mapped.
Observable from outside. Skilled observers — experienced fighters, Researchers, Inventors — can detect a liminal skill by watching how it behaves under pressure. The leak is the tell. This makes liminal-state survivors legible to anyone who knows what they are looking for.
Breaking the pattern resets the clock. If the survivor is forced to violate their self-imposed conditions during the liminal period — by stress, disruption, or deliberate external interference — the evolution fails. The skill returns to its prior state. The survivor must begin the process again. This is exploitable: there is an established economy of hired disruption, where factions and rivals pay attackers specifically to interrupt a target's liminal state, not to kill them, but to prevent them from becoming something harder to deal with.
Prerequisites
Prerequisites are what make a skill possible to enfix. They are not granted by the System — they are accumulated through what the survivor does and learns. Having a prerequisite does not unlock a skill; a skill may require several prerequisites, and all must be met before enfixing is possible.
Two acquisition methods
System Observation
The System watches what a survivor does in the world and quietly awards prerequisites as experiences accumulate. The survivor does not choose when this happens and may not know what they are accumulating toward. A survivor who has spent years hunting in wilderness terrain may have been collecting prerequisites for skills they have never heard of.
Prerequisites earned this way are visible on the survivor's System interface. They can see what they hold, even if they cannot yet see what it unlocks.
Certified Method
Prerequisites acquired through formal knowledge verification. The System administers tests in a pocket dimension, via interface knowledge checks, or through assessments given by a System-certified Trainer.
Trainer certification is granted through institutions built by Rulers, Labor Guilds, Explorer Tribes, Preacher Churches, and similar organizations. Controlling certification is controlling access — an institution that trains Trainers determines who can meet prerequisites for the skills those Trainers certify.
Tier unlock — the tree is the prerequisite chain
Tier access is not separately granted by the System. A survivor cannot enfix an Adept skill until both Novice slots are filled — not because the System issues permission, but because Adept skills require both Foundational skills as prerequisites. The tier names describe the prerequisite structure of the skills within them, not an administrative gate the System controls.
Foundational skills carry no skill prerequisites. They are the base on which everything above stands.
Adept skills require both Foundational skills as prerequisites. Both slots must be filled before any Adept skill can be enfixed.
Journeyman, Expert, and Master skills follow the same logic upward. Each tier's skills prerequisite skills from the tier below. The tree is load-bearing from the bottom at every level.
The cascade consequence. Because the tier structure and the prerequisite chain are the same thing, losing a Foundational skill does not merely lose that skill — it destroys the prerequisite of every Adept skill built on it, which cascades through Journeyman, Expert, Master, and pulls the Pinnacle down with it. There is no tier above the point of collapse. The entire tree falls as the structural logic of its own design executes.
How prerequisites shape skills
The number and difficulty of prerequisites required for a skill are not arbitrary gates. They are the source of that skill's conditions — and therefore the source of its output ceiling.
More prerequisites = stronger skill. A skill requiring many prerequisites will carry more conditions for activation. More conditions mean a higher output ceiling. The prerequisite chain is the reason the skill can reach where it reaches.
Harder prerequisites = stronger skill. Difficulty scales the same way. A prerequisite that requires years of specific experience produces a more demanding condition than one that requires a week of study. The harder it was to earn, the higher the ceiling it creates.
Prerequisites determine condition type. The path taken to earn prerequisites shapes what conditions appear in the resulting skill. A Lover whose prerequisites ran through genuine Affinity accumulation gets skills with Relational conditions. The conditions reflect what the survivor did to get there.
Skills as prerequisites. A skill in one slot can be a prerequisite for a skill in a later slot. Simply holding the skill qualifies — no depth threshold is required. The chain is where tree difficulty lives. Some trees develop quickly because the prerequisite chain is short. Others are slow because reaching the third skill requires the second, and the second required conditions most survivors never encounter.
Prerequisites survive skill loss. If a skill is lost — through cascade, sacrifice, or other mechanism — the prerequisites that built it remain. The System's observation history does not reset when a skill is stripped. Recovery begins from a foundation rather than from nothing.
Prerequisite-free enfixing
Locking a destination
A survivor can enfix a skill into a slot without meeting its prerequisites — provided they have knowledge of the skill. Knowledge from a Researcher, a Trainer, or direct observation qualifies. Once enfixed this way, the slot is locked and the skill cannot be used until every prerequisite is met.
The lock is permanent. A slot with a prereq-enfixed skill cannot be released. The survivor cannot change their mind. The slot remains occupied and non-functional until the prerequisites are met — however long that takes.
The survivor can feel it. A locked slot is not purely administrative. The skill sits in the survivor's awareness — present in shape, inaccessible in use. The feeling has been described as a word on the tip of the tongue that cannot be spoken.
Visible to others. A locked slot appears on the survivor's System record. It announces intention. Anyone with access to their record can see where they are going.
The cost is opportunity. Prereq-enfixing sacrifices a functional slot for a future one. The survivor pays in present capability for a future ceiling — a bet on who they are becoming, not who they are now.
Prerequisite destruction
Making a truth false
A prerequisite is a statement the System treats as true about a survivor. Destroy the truth of that statement and every skill built on it collapses — instantly, without delay, mid-combat if necessary. This is prerequisite destruction: not the loss of a skill, but the removal of what the skill was standing on.
Hard targets. Experience and knowledge prerequisites are difficult to destroy because the System's observation record of them does not reset. You cannot unmake what someone has lived through or genuinely learned. Even after total skill tree collapse, these accumulated prerequisites remain on the survivor's interface — intact, waiting to rebuild on.
Soft targets. External-condition prerequisites — those tied to relationships, oaths, objects, or statuses — are vulnerable. Any act that breaks the underlying condition destroys the prerequisite. The survivor does not need to be attacked directly. Breaking the oath, severing the relationship, destroying the object, or revoking the status is enough. The cascade follows immediately.
Deliberate self-destruction. A survivor can knowingly destroy their own prerequisites. The reason to do it is strategic: if a prerequisite is attached to a condition that has become a liability — an oath resented, a relationship that constrains — invalidating it frees the skill slot from that condition. The skills above it are lost. The condition is escaped. The System permits this without judgment.
The collapse is instant. There is no grace period. A prerequisite destroyed mid-fight produces mid-fight cascade loss. This makes soft-target prerequisites a genuine combat vulnerability — and identifying them in an opponent's tree a form of high-level tactical knowledge.
Skill sacrifice
A weapon that burns itself
Skill sacrifice is a class of skill whose activation condition is the destruction of its own prerequisite chain. To fire it, the survivor burns the prerequisites it was built on — sacrificing them in the act of use. The effect can be directed outward, targeting a specific aspect of another survivor's foundational knowledge or prerequisite structure. Once fired, the skill's own prerequisites are gone, and the skill itself typically falls with them. It is not a repeatable weapon in the conventional sense.
The cost scales the power. A sacrifice-based skill built on shallow prerequisites is a weak weapon. A sacrifice-based skill built on deep, hard-earned prerequisites — years of research, rare experiences, knowledge no one else holds — can be catastrophic on activation. The attacker pays everything the skill cost them to build. In return, the effect reflects that full cost.
Targeted destruction. The effect of a sacrifice skill is not generic damage. It targets something specific in the opponent — a foundational affinity, the ability to accumulate a particular kind of knowledge, a prerequisite the attacker has identified as load-bearing. This requires prior research into the target's tree. The more precisely the attacker understands what the target's skills are standing on, the more surgical — and more total — the resulting collapse.
Why foundational prerequisites resist it. Most foundational prerequisites rely on experience or knowledge — hard targets by nature. A sacrifice skill aimed at destroying a purely experiential foundation often cannot reach it. This is part of why survivors who build their foundation on lived experience rather than external conditions are making the structurally safer long-term choice, even if external-condition foundations produce higher output ceilings.
Essence Defiance
Essence Defiance is the act of pushing Essence past the established output ceiling of a skill — or through the body and soul directly, with no skill at all. In either case, the survivor is operating outside the System's registered patterns. The effects are real. The cost is proportional to how far outside those patterns the survivor goes.
Skill-based Defiance — the mechanism of evolution
When a survivor pushes Essence through an enfixed skill past its conditions-established ceiling, the skill enters liminal state. If the survivor sustains the pattern without breaking their self-imposed conditions, the System recognizes what is being built and issues an upgrade — new conditions written into the skill's structure, ceiling raised to match what the survivor was already doing. Skill-based Defiance is the engine of all skill evolution. The System does not generate stronger skills. It patches what survivors have already demonstrated.
The skill is the channel. A skill's conditions and prerequisite structure act as a shaped pathway for Essence. When a survivor Defies through a skill, they are pushing past the channel's designed capacity — but the channel still exists. It gives the Essence a partial shape and gives the survivor partial control over the output. This is what distinguishes skill-based Defiance from skillless Defiance.
Risk scales with the push. Minor Defiance — nudging slightly past the ceiling — produces minor instability: harder-to-direct effects, slightly unpredictable output. Significant Defiance produces damage. The damage is not to the skill. It is to the survivor. Body damage is the more predictable outcome. Soul damage is the more dangerous one.
The System patches to prevent mutilation. When a survivor's Defiance pattern stabilizes into a recognized shape, the System issues an upgrade specifically to formalize what the survivor is doing — bringing the behavior back within registered parameters. The upgrade is partly containment. A survivor who Defies consistently forces the System to keep up or watch the damage accumulate.
Skillless Defiance
No channel. No ceiling. No upgrade pathway.
A survivor does not require a skill to perform Essence Defiance. Essence can be pushed directly — through the body and soul alone, with no System-recognized channel to route it. The effect is real. The output can be significant. The risk is categorically higher than skill-based Defiance, because nothing is shaping what the Essence becomes when it exits the survivor.
What the Essence becomes. Without a skill channel, output is shaped by the survivor's body, their elemental affinities, their intent, and factors the System does not have reliable models for. Effects are frequently uncontrolled, disproportionate to intent, or categorically unexpected. Two survivors attempting the same skillless Defiance may produce entirely different results.
Stats lower the risk — not the unpredictability. Higher physical and combat stats give the body greater tolerance for Essence loads before structural damage begins. A high-stat survivor doing skillless Defiance is harder to kill in the process. They are not better at directing the result. Stats provide endurance. They do not provide control.
No evolution pathway. Skillless Defiance produces no skill evolution. There is no skill for the System to patch. The System observes and records — the behavior is classifiable as Defiance — but there is no framework to upgrade. Each use carries the same risk as the last. The survivor gains power in the moment and builds no permanent structure around it.
Who practices it. Skillless Defiance is the power path of survivors who do not trust the System, cannot access skill infrastructure, or deliberately choose to operate outside the System's accounting. It is also used by skilled survivors who need effects their skill tree cannot yet produce, or who want to act without leaving a classifiable System record. A skill activation is logged. Skillless Defiance is observed but not named.
Soul Mutilation
The unknown category
All Defiance carries injury risk. Most Defiance damage falls within status conditions the System can name, track, and in some cases cure — body damage, Essence disruption, elemental instability. Soul mutilation is what happens when the damage falls outside the System's taxonomy entirely. The System's interface cannot fully describe or address it.
Unclassifiable by design. Soul mutilation results from Essence moving through the body and soul in configurations the System has no registered profile for. The display reads as anomalous: partial status text, unresolved condition names, no cure pathway listed. The System knows something has happened. It cannot say what, or how to reverse it.
Survivor-specific and non-standard. No two instances of soul mutilation are identical. The damage depends on the survivor's affinities, the nature of the Defiance that caused it, and factors that remain poorly understood. Researchers have documented effects that include: altered Essence flow, suppressed skill categories, changes to elemental affinity, shifts in perception, and in extreme cases, fundamental changes to the survivor's identity and relationships with the System.
The System can sometimes contain it. When a survivor's Defiance pattern stabilizes, the System may issue upgrades that route around the affected pathways — managing the damage without reversing it. This is containment, not cure. What has happened to the soul's structure does not change. The System works around it.
Preachers are the only meaningful intervention. Cleric skills can address some soul mutilation conditions at sufficient depth. Preacher-brokered intervention is the only class with documented success rates — and those rates are poorly recorded, highly variable, and dependent on the specific nature of the mutilation. Some conditions resist all known intervention.
The anchor case
Abreasa
Essence Defiance has a known ceiling case. Most survivors who Defy do so in bounded amounts — a push past a skill ceiling to drive evolution, a desperate gambit in combat, a deliberate choice to operate outside the System's naming. Abreasa is what it looks like when someone, or something, Defied without stopping.
Whether Abreasa was a survivor who Defied at a scale that transformed them into something the System cannot classify, or something else entirely, is a question that does not have a settled answer. What is known is that the Cult of Abreasa's surviving members carry active soul mutilation conditions the System cannot resolve. The soul damage does not decay. It does not respond to standard intervention. The System marks it as unresolved and provides no cure pathway.
We don't talk about Abreasa.
The Crafter Workbench
Crafter onlyThe workbench is a System interface available exclusively to Crafter caste survivors. It is a permanent, running record of every creation they have produced — not limited to material objects. A song, a negotiated arrangement, a performance, a designed process — anything the System recognizes as a Crafter's output can appear as a workbench entry. For Inventors and Engineers specifically, the workbench is also the site of skill research: the space where skill patterns are tested, mapped, and developed before they reach the broader world.
What the workbench tracks
Grade
Every entry carries the grade the System assigned to that creation at the time of production — F through Legend. Grade reflects the quality of the output against the Crafter's current materials, skills, and practice depth. Two Crafters with identical skills can produce different grades from the same materials based on how deeply each understands the craft. The workbench makes this difference visible over time.
Affinity Generated
Every entry also tracks the Affinity score the creation produces between people who interact with it. A well-made item generates relational warmth between giver and recipient. A song performed well changes how people feel about each other. The workbench records this — not as an approximation, but as the actual score the System measures. This makes the workbench a social instrument as well as a craft record.
The two-grade system — universal
Blueprint grade
The grade of the work as designed, written, or formulated — a recipe, a schematic, a composition, a formula. Blueprint grade is fixed once the work is complete. It represents the ceiling of what any production of that work can achieve. A recipe graded at A produces a ceiling of A for any Cook who follows it. No execution skill can exceed it.
Production grade
The grade of a specific instance of the work being realized — a forging session, a performance tonight, a synthesis batch, a meal cooked under pressure. Production grade is determined by the executor's skill, Essence investment, material quality, conditions, and depth of understanding of the blueprint. It cannot exceed the blueprint grade. It very often falls short of it.
Blueprint grade sets the ceiling. Production grade is where the output actually lands. Both must be present at their highest for the highest output to be achieved. This creates a structural distinction between design talent and execution talent — two skills that are entirely separable, that a Crafter may hold in very different measure, and that an institution may need to source from different people entirely.
The designer who cannot execute. A songwriter who writes A-grade compositions but performs at C never triggers A-grade transformation effects in their own work. Their blueprints have unrealized ceiling. They need a performer whose production grade can reach it.
The executor who cannot design. Exceptional execution ability, capable of A-grade production — but their original blueprints are D-grade. The ceiling is too low. No execution skill overcomes it. They need someone else's blueprint to carry.
The workbench records both. Blueprint entries document what was designed and at what ceiling. Production entries document specific instances — which blueprint, what execution grade, who received the output, what effects were measured. A Crafter's workbench is simultaneously a record of their design capability and their execution history.
Transformation thresholds — universal
All Crafter output is subject to the same grade-based transformation thresholds. Below a certain point, grade measures quality — the output does what it does, better. Above that point, Essence investment has done something different to the object. It has changed what kind of thing it is. The specific nature of the transformation is shaped by the Crafter's elemental Perk portfolio — earned through Achievements, never inherent to the class.
F through C
Purely physical quality within varying ranges. No Essence transformation. C is the factory production ceiling — not because factories are inefficient, but because Essence transformation cannot be automated. The System requires individual Crafter investment to cross the threshold.
B — First emergence
Transformation is real but subtle and inconsistent. It does not fire the same way every time. Most people cannot identify it as the source of what they are feeling or noticing. A B-grade meal leaves people feeling slightly more capable than they should. A B-grade blade occasionally cuts something the metal alone has no business cutting. Present but uncontrolled.
A — Clear transformation
Clear, functional, recognizable magical transformation. The output does things it should not be able to do. Experts can identify it. Institutions have opinions about it. This is where Crafter output becomes genuinely dangerous and genuinely coveted. Elemental Perks earned through Achievement manifest at this grade and above — shaping what kind of transformation the output produces and in whom.
S — Transformation defines
Transformation is the defining characteristic. The object is no longer primarily a sword, a song, a meal. It is a magical object that happens to take that form. Consumption, use, or prolonged exposure at this grade produces permanent structural changes in the recipient. Boons stack across different S-grade outputs but require the convergence of S-grade materials, S-grade technique, and S-grade blueprints — each independently scarce.
Myth — Legend
Transformation operates at a scale that exceeds the object's immediate context. Myth-grade output changes people and situations the object never directly touched. Legend-grade output changes something about the world itself. The System takes note. Other entities may as well.
Crafter output as skill conditions — universal
Any qualifying Crafter output can function as a State-type skill condition. The System monitors the quality and presence of Crafter objects in real time — what is being worn, wielded, consumed, or operated within — and applies that monitoring as a condition check on skills that reference it. The condition language varies by class but the mechanism is universal.
Activation conditions on Active skills. A skill requiring a qualifying Crafter output to activate fires only when the condition is currently met. The required output grade determines how demanding the condition is — and how high the ceiling it creates in return.
De-activation conditions on Sealed and Passive skills. A Sealed or Passive skill conditioned on Crafter output runs continuously unless the condition is violated — the meal window closes, the item is lost, the survivor leaves the facility. The skill suspends. When the condition is restored, the skill resumes. No cascade.
The stricter the condition, the higher the ceiling. A skill conditioned on "currently wielding an S-grade weapon forged from a specific rare material" is extraordinarily demanding — and produces a correspondingly extraordinary output ceiling. Survivors who build Crafter-output conditions into their skills accept supply dependency in exchange for output that would otherwise be unreachable.
Supply dependency is a tactical vulnerability. Destroying, stealing, or degrading the Crafter output a survivor's skills depend on is a legitimate attack vector. Interdicting supply chains is prerequisite destruction by attrition — the skills remain in the slots, intact, simply unable to fire.
Permanent boons — S grade and above
At S grade and above, Crafter output does not merely affect the recipient during use or consumption — it permanently changes something about their Essence structure. The specific change depends on the output type, the Crafter's elemental Perk portfolio, and factors the System does not fully disclose. What changes stays changed.
Boons stack across different outputs. A survivor who has received permanent boons from five different S-grade outputs has five distinct stacked structural changes. The same S-grade output consumed twice produces diminishing returns on the same boon — but a different S-grade output produces a different boon independently. Building a meaningful boon history requires access to genuinely varied S-grade outputs across a career.
S-grade output is genuinely scarce. Producing it requires the convergence of S-grade materials or ingredients, S-grade procedural technique developed through sustained Master-tier practice, and S-grade blueprints that often require Master skills just to execute correctly. Any one is difficult. All three simultaneously is rare. A survivor with a meaningful boon stack has had extraordinary access to extraordinary Crafters.
A biographical record. A survivor's permanent boon stack reflects who has trusted them with rare things and who has had reason to invest in their capability. It is not displayed as a summary field on the System interface. Researchers who study the correlation between specific Crafter outputs and specific structural changes can infer it. Most cannot.
Invisible prerequisite generation — universal
High-grade Crafter output quietly generates System Observation prerequisites for recipients and users. When a survivor consumes, uses, wears, or is meaningfully affected by qualifying output, the System may record a prerequisite on the survivor's interface — one they may not have noticed, sought, or known was possible. The Crafter is not informed. It does not appear on their workbench as a prerequisite grant.
Invisible to the Crafter. Discoverable only through Researcher analysis of the correlation between specific outputs and specific prerequisite appearances — or through a recipient who notices and tells them.
When the Crafter learns. A Crafter who is told that a specific piece of their output generates a specific prerequisite now holds covert power they did not seek — the ability to produce that output for specific people and withhold it from others. The System has no opinion on how they use this knowledge.
Institutional analysis. An institution that employs both a high-grade Crafter and a Researcher to study their output can optimize production to generate specific prerequisites for specific people — and withhold that production from others. This is prerequisite access controlled through the appearance of ordinary supply.
Certification facility — Crafter + Engineer
From passive observation to active certification
When a Crafter works with an Engineer to design a production facility, the System recognizes the structured, intentional nature of what is being produced and registers qualifying output as Certified Method prerequisites rather than passive System Observation. The principle is universal — a Cook's certification kitchen, a Smith's certification forge, an Alchemist's certified laboratory. The Crafter provides the output; the Engineer provides the infrastructure that makes the System read the production event as formal certification.
What the Engineer contributes. Precision systems, controlled conditions, workflow processes that reduce execution variability, and the formal institutional structure the System recognizes as certification infrastructure. The design makes the Crafter's ceiling more reliably reachable and makes the production event legible to the System as intentional.
The facility is an asset and a target. Requires significant investment to establish and both Crafter and Engineer to function at designed capacity. It can be found, disrupted, and destroyed. Losing it stops new certified prerequisites from being produced — but does not remove prerequisites already granted.
Workbench intelligence
The scariest record in the System
Workbench sharing is voluntary — except when it isn't. Operating contracts, certification submissions, and institutional employment agreements can all compel disclosure. A Ruler who requires registered Crafters to maintain accessible workbench records has a surveillance instrument built into the System itself. Any institution can build the same. The data is the easy part.
Staffers design and maintain the database. Without them the records sit in a pile. They are also the primary internal breach vector — the people who operate the system have more access than almost anyone, and can be hired away, bribed, or make independent decisions about what the information they hold is worth.
A Banker controls storage and access — who can retrieve what, under what conditions. Controlling the storage layer controls the data. A Banker who leaves or is compromised takes the access architecture with them.
Researchers perform analytics. Raw workbench data is not intelligence. Grade trajectories, Perk portfolios, approaching transformation thresholds, prerequisite generation patterns — these require Researcher analysis to become actionable. A database without a Researcher is a room full of paper.
Lawyers defend against the legal challenges the system generates. Compelling disclosure is contestable. Crafters whose records were used against them will sue. Data breach victims will sue.
Any institution can build this. Not just Rulers — Labor Guilds, Trade Companies, Preacher Churches, large Crafter enterprises. Explorer Tribes typically cannot; their structure does not support the administrative depth required. An institution with the full picture knows: who is approaching the A-grade threshold before the market does, which Perk portfolios exist and what magical output they produce, which blueprints have never been executed at their own ceiling, and which Crafters — assembled under contract — would produce output with combined properties no one has built before.
Blueprint intellectual property
A blueprint is a document. It can be memorized, copied, and stolen without leaving obvious evidence. Who owns a blueprint produced during institutional employment depends entirely on what the Crafter agreed to before they started. An institution that holds a Crafter's blueprints controls the ceiling of anyone who wants to execute that work. A Crafter who retains ownership and licenses execution rights retains leverage — and ongoing royalty potential. How good the Crafter's lawyer was at the moment of the original agreement is the answer to almost every blueprint ownership dispute that follows.
Inventor — empirical research
Learning by doing
An Inventor can activate skills held on their workbench without enfixing them into their slot tree. The skill exists on the workbench as a mapped structure — condition-defined, System-visible — but not committed. Using it is Skill-based Defiance: the skill's conditions provide a partial channel, which gives the Essence some shape, but the absence of formal enfix means that channel is looser than it would be in a filled slot. The risk sits between standard skill-based Defiance and skillless Defiance.
Includes cross-caste skills. An Inventor who has a Combatant-class skill on their workbench can Defy through it. Without the combat stats that normally establish the output floor, the result is structurally unstable — the conditions-established ceiling exists, but the base that would anchor the output does not. The effect fires. What it does is harder to predict than workbench Defiance through a Crafter-class skill.
Evolution occurs in the workbench. An Inventor who repeatedly Defies through a workbench skill can drive it through liminal state and into a System-recognized upgrade — without ever committing the slot. The skill develops on the workbench. When the Inventor eventually enfixes it, they are committing a skill that has already been researched past its foundational state. The slot cost is paid once. The Defiance cost was paid during research.
The workbench is intelligence. An Inventor's workbench holds everything they have researched but not committed to. It is a record of their interests, their directions, and in some cases their intentions. Institutions value it accordingly — and so do rivals. Workbench access is not given lightly.
Blueprint destruction is a targeted attack. If an Inventor is mid-Defiance through a workbench skill and the blueprint is destroyed — stolen, burned, or the workbench disrupted — the channel collapses while Essence is moving through it. The Essence has nowhere shaped to go. The result is typically worse than the Defiance risk the Inventor was already accepting.
Engineer — formal research
Learning by mapping
Engineers do not use the skills they work with. Their relationship to a skill is entirely theoretical: they map its condition structure, model its prerequisite chain, document its output behavior, and produce a blueprint — a System-recognized formal description of the skill's architecture. The blueprint can be read, studied, encoded into Skill Orbs, and used by Trainers to certify others in the skill's prerequisites. An Engineer who has fully blueprinted a skill understands its structure at a level that often exceeds survivors who have actually used it.
Engineers can inherit Inventor workbench skills. An Inventor who has developed a skill through Defiance research holds empirical knowledge — rough, personal, and shaped by their specific experience with the skill. An Engineer can take that workbench skill and formalize it: translating experiential knowledge into a clean, reproducible blueprint. Some of the Inventor's texture is lost in translation. The blueprint is more legible and more deployable than what it was based on.
Engineers are intelligence assets. A fully blueprinted skill reveals its entire condition structure — including which conditions are destroyable soft targets. An Engineer who has mapped a survivor's skill tree knows that survivor's vulnerabilities more precisely than the survivor may. Institutions that employ Engineers guard that knowledge carefully. Rival institutions treat Engineer theft as a high-priority operation.
The knowledge pipeline
Neither Inventor nor Engineer is upstream of the other. They are parallel knowledge paths that feed each other and both feed into the broader certification system.
Inventor — Empirical. Discovers through Defiance. Produces working skill patterns through use. Knowledge is personal, rough, and experientially validated.
Engineer — Formal. Discovers through mapping. Produces blueprints and Skill Orbs. Knowledge is clean, reproducible, and deployable at institutional scale.
Researcher — Synthetic. Takes empirical data from Inventors and formal structures from Engineers and finds the gap between them — where the theoretical model and the observed behavior diverge. That gap is where undiscovered patterns live. Researcher-published findings, when System-validated, become prerequisites: knowledge other survivors must hold to access certain skills.
Trainer — Institutional. Takes confirmed patterns and certifies others in the prerequisites those patterns require. Trainers do not discover or validate — they deploy what has already been established. Controlling Trainer certification is controlling access to the skills those Trainers certify.
Institutions that hold all four — Inventor, Engineer, Researcher, Trainer — do not just have power. They have compounding power. Every skill pattern they develop stays internal until they choose to release it. Every new pattern they discover becomes a prerequisite they control. The research pipeline is, in practice, a mechanism of institutional lock-in.
Skill Orbs
Physical certification objects
Skill Orbs are System-interface objects that instantiate a pocket dimension test at a fixed location, allowing survivors to complete certified prerequisite verification without a live Trainer present. When a survivor interacts with an active Orb and meets the underlying knowledge or experiential prerequisites being tested, the System administers the assessment through the Orb's dimensional aperture and, if passed, records the certified prerequisite on the survivor's interface.
Manufactured by Engineers. Skill Orb production requires high-grade monster cores as the primary material component — the core provides the dimensional substrate the Orb uses to instantiate the test space. Orb quality scales with core grade. A higher-grade core produces an Orb capable of certifying more complex prerequisites.
Rarity is institutional. The number of Orbs in circulation in a territory is a direct function of how many Engineers an institution can deploy and how reliably they can source high-level monster cores. An institution with both produces Orbs at scale and controls local prerequisite access. An institution without is dependent on live Trainers — slower, more expensive, and impossible to deploy at distance.
Orbs can be stolen. Orbs can be destroyed. Control of an Orb network is control of who in a territory can access the skills that network certifies. Losing that network — through theft, targeted destruction, or the death of the Engineers who maintain it — is a strategic blow that takes years to recover from.
Cook — class expression
The settlement's Essence infrastructure
The Cook expresses all universal workbench mechanics through food — the most intimate delivery mechanism available, because it operates from the inside. Recipe grade caps execution grade. Transformation thresholds govern what meals do at each grade. Meal quality functions as a State-type skill condition. S-grade meals produce permanent boons. Prerequisite generation happens invisibly to the Cook. What is specific to the Cook is the intimacy of the vector and the scale of the dependency it creates across an entire population.
Meal as State condition. "Currently within the active window of a qualifying meal" is a State condition like any other. A survivor who has built a meal condition into a skill does not permanently lose that skill when the window closes — the skill suspends and resumes when the condition is re-met. The stricter the meal requirement, the higher the ceiling it creates. A skill conditioned on "currently within two hours of an A-grade meal containing a specific rare ingredient" is extraordinarily demanding and produces proportionally extraordinary output.
A-grade Essence contact. At A grade, a meal interacts directly with the eater's Essence pool — not just their body. Temporary effects on pool capacity, Essence flow, accumulation rate, Affinity generation, and stat ceilings. Whether a Ruler operates this openly or quietly depends entirely on their goals and propaganda capability. The System does not distinguish between a population that consented to Essence optimization and one that did not.
S-grade permanent boons. An S-grade meal permanently changes something about the eater's Essence structure. What specifically depends on the recipe's elemental Perk profile. A settlement whose population has accumulated multiple S-grade meal boons has been fed by an extraordinary Cook — with access to S-grade ingredients, S-grade technique developed through Master-tier practice, and S-grade recipes that require Master skills to execute — for an extraordinary duration.
The workbench as population record. A Cook's production entries record what was made at what grade and what Affinity was generated — not what prerequisites fired or what Essence effects occurred in each eater. But a Cook who has fed the same community for years has built a longitudinal Affinity map of that community without intending to. An institution collecting that Cook's workbench receives both recipe intelligence and years of communal feeling documented as data. The most intimate workbench type, because it records what happened inside people.
Connection to the Civilian economy
High-affinity creations are naturally valuable to Civilian classes — particularly to Lovers, whose skill prerequisites run through genuine Affinity accumulation that cannot be faked or rushed. A Crafter whose workbench shows a history of high-affinity output is producing something Civilians cannot produce for themselves: a shortcut through the hardest prerequisite they have. The Crafter who made the song that bonded two people may have contributed more to a Lover's skill progression than years of the Lover's own social effort. This relationship is invisible to most Combatants and underestimated by most institutions.
