Attributes

The Terrain family includes Snow, a mental, intuitive, Intelligence-governed skill with a 30,000-hour curve. Snow has symmetric 0.20 ordinary correlation with Plains, Forest, Hills, Wetlands, and Urban. It is an overlay skill: snow-covered forest still uses and trains Forest while Snow blends into the check. Cover conservatively splits the existing road-discounted exposure between Snow and the underlying biome.

The strategic interface represents attributes, skills, schedule activities, condition metrics, Fervor, Morale, Age, Virtue, and Religion with recolourable CSS masks. Most use locally vendored monochrome Game Icons; arm and leg Strength and Agility plus Immunity retain the original strategic-interface artwork for legibility at compact sizes. Labels and tooltips remain available to assistive technology. The maximum value of your characters' attributes is determined by their genetics, but the actual value may be quite a bit lower if they are not properly conditioned. For example, even if you have the theoretical ability to build a large amount of muscle, if you have poor nutrition or don't exercise then you will realize very little of it. Conditioning is different for each attribute, but generally no one will be able to condition all of their attributes to their maximum potential due to there only being 24 hours in a day.

Attributes are grouped between Chest/Stomach/Head/Limbs (L/R, A/L). Damage to one of these areas will affect all attributes within.

Chest

Endurance

Represents the strength of your heart, capacity of your lungs, and proportion of slow-twitch/fast-twitch muscle fiber. It determines how long you can go without suffering from exhaustion and how fast you move when traveling. Conditioned by traveling on foot.

0. Asphyxiated
1. Dainty sheltered nobles
2. City-folk
3. Knights and peasants
4. Professional soldiers
5. Adventuring heroes
6. Undead (cannot be tired)

Stomach

Immunity

This is essentially a combination of the liver, spleen, and other organs which regulate your immune system and ability to filter out toxins.

0. AIDS
1. Infants
2. Sheltered nobles and children
3. Rural commoners and knights
4. Elves and city-folk
5. Vampires (immune to disease)

Gut

Your stomach, intestines, pancreas, and other organs involved with your digestive system. Determines how edible food needs to be in order for you to effectively digest it and how much variety you need to be decently healthy. Cooking makes food more edible, but food that is more fibrous and less nutritious can only be improved by so much.

0. Vampires (cannot digest food, must get calories directly from blood glucose)
1. Elves (can only eat meat, fat, and luxurious elven plants)
2. Nobles, orcs
3. Professional soldiers, goblins
4. Peasants (can survive almost entirely on grains without huge penalty)
5. Livestock

Limbs

These attributes are separate among 4 limbs:

• Right arm
• Left arm
• Right leg
• Left leg Every physical check will use some proportion of these. For example, swinging a sword in your right hand is largely dependent on your right arm, but your left arm is also being used for balance and your legs are helping put force into it. Your torso is also twisting to support this, but rather than being a separate limb, your torso is essentially a fuzzy mix of all limb attributes (mostly arms).

Strength

Proportional to the total muscle mass of the limb. Arm-strength is important for attack damage, climb speed, and how well you keep your balance while blocking attacks. Leg-strength is important for movement speed and jump height.

0. Cripple
1. Child
2. Adult woman, pubescent boy
3. Adult man
4. Trained knight
5. Olympic athlete

Agility

The speed of your muscular reflexes and your ability to control them. Arm-agility is important for accuracy and parrying, leg-agility is important for stealth and dodging.

0. Paralyzed, unaware, or tied up
1. Drunken oaf, orcs, zombies
2. Clumsy, goblins, skeletons
3. Professional soldiers and knights
4. Heroes, surgeons, locksmiths
5. Elven heroes

Head

In theory eyesight/hearing should be further subdivided into eyes/ears for damage purposes, while intelligence and instinct are brain. In fact, ask a neurologist but intelligence/instinct would be correlated with different physical locations in the brain. But this is fine for now, we do not need infinite detail for the MVP.

Intelligence

The depth at which your character can think. Intelligence governs learning and mastery for Physiology, Anatomy, Cooking, Religion, Bestiary, and the Terrain leaves. It does not add to their final checks.

0. Not capable of conscious thought
1. Low-functioning autistic, toddler
2. Would struggle to learn even basic math
3. Can learn high-school-level math
4. Can learn college-level math
5. Can meaningfully contribute to the field of mathematics

Instinct

Your ability to make snap judgements without thinking. Instinct governs learning and mastery for Will, Insight, Charm, Command, and Deception. It does not add to their final checks.

0. Unconscious
1. Takes a couple seconds to respond if you ask them a question
2. Absentminded
3. Alert
4. Veteran captain
5. Enlightened monk

Eyesight

0. Blind
1. Needs glasses, many fantasy enemies like goblins or zombies
2. Below average human
3. Above average human
4. Elven warrior
5. Hawk, elven archer

Hearing

0. Deaf
1. Muffled, many fantasy enemies like goblins or zombies
2. Attended too many rock concerts
3. Has never been to a rock concert
4. Deer
5. Blind monk

Skills

Every skill has exactly one governing aptitude: Intelligence, Instinct, or Agility. Aptitude controls training speed and the effective-rank limit; trained skill rank supplies the check itself.

Training

Skills increase on a much longer timescale than is conventional for RPGs. They are not increased via an abstract XP/leveling system, and very little of their value comes from using them during tactical play. Instead they are trained through activities in the character's off-screen settlement-downtime schedule. Individual skill-study allocations are not available.

Combat Training practices the leaf skills relevant to the equipped weapons plus Dodge, Block, Balance, and Will; it includes both sparring and target practice. Carousing trains Charm, improves Morale, and carries a small Virtue penalty. Prayer, Labor, Thievery, and Raiding retain their related training and strategic results. Profession activities cover Physiology, Anatomy, Knife, Tailoring, Smithing, Command, and knowledge of the settlement church's religious tradition. An activity conserves its training time when it covers several skills rather than awarding the full allocation to every skill. Travel never performs scheduled settlement activities. Activity rows preview the signed Gold, Virtue, Morale, and Fatigue generated per day by the current allocation; notoriety-producing activities display that cost as negative Virtue. Leisure is the unallocated remainder and includes sleep.

Selecting an explicit activity icon previews and performs one continuous one-to-24-hour interval using the same training and outcome rules. Its preview is based on the chosen duration; Prayer/Meditation and Carousing are nonlinear, so increasing their duration has diminishing Morale returns. Immediate activity never includes implicit Leisure or modifies the recurring allocation.

A character may join multiple YAML-defined organizations. Each organization chooses its own name, chapters, recognition, admission fee, recurring dues, rank names and requirements, curriculum, rewards, and privileges. Requirements may freely mix skills and professed religion; skills never imply membership. A character can present as exactly one active, dues-current organization at a time (or none). Presentation controls recognized privileges such as bearing arms or wearing armor where settlement policy would otherwise forbid them.

Organization training and professional activity are available through the schedule while the character is at a chapter. Rank advancement follows the next rank's YAML requirements rather than universal apprentice/journeyman/master thresholds. Skills with no invested training hours remain omitted until training first awards hours.

An ordinary day generates 600 fatigue-reservoir units before tiring activities. Leisure removes 100 units per hour, so six hours exactly offsets ordinary wakefulness. Labor adds another 50 units per hour. Leisure beyond six hours first removes activity fatigue, then fatigue carried into the interval; only the portion of the interval after the reservoir reaches zero earns morale, approaching 4 points per full qualifying day with a 200-unit diminishing-return scale. The schedule displays a one-day preview, but the server awards the result proportionally to the settlement-downtime time actually applied. Earned Leisure morale is kept as one refreshable source capped at 4 points, rather than being projected from the post-rest schedule or stacked into separate events. It decays at a fixed rate when no qualifying Leisure is occurring; qualifying Leisure refreshes it while adding the newly earned amount. This makes the result independent of whether downtime is applied all at once or through frequent synchronization. The compact schedule preview shows one Fatigue point per 100 reservoir units: Labor therefore shows +0.5 per hour, while Leisure includes baseline and recovery so all visible Fatigue rows sum to the authoritative net change. Positive preview values remain green and negative values red, including negative Fatigue values that represent recovery.

The rank meter is a five-segment display using the same yellow-green, yellow, orange, red, and violet progression as equipment repair difficulty. Daily allocations are changed in 15-minute steps with the left/right buttons or mouse wheel. Clicking a displayed allocation opens a time field. It accepts h or hh as whole hours, h:mm or hh:mm, and compact three- or four-digit times such as 830 or 0830; entered values snap to the nearest 15 minutes and may not exceed 24:00. The underlying schedule stores minutes, and the Leisure allocation shows the unallocated remainder. The editor updates these values immediately, serializes background saves, and reconciles with the server after the latest change is saved so live updates cannot momentarily restore an older plan. A failed save leaves the optimistic plan visible and presents a Retry action; making another edit also retries using the newest plan. Compact column icons label Currency (💎), Virtue (⚖️), Morale (🙂), Fatigue (💤), and daily allocation (⌛); each icon exposes the same label to assistive technology.

Character summaries use that same five-color rank progression on compact, keyboard-focusable icons. Equipped hands contribute one icon for every unique weapon leaf they exercise, including every leaf of a hybrid weapon. Armor contributes one silhouette icon for the highest equipped coverage tier, including an outlined unarmored silhouette at zero coverage, and uses the stronger healthy Dodge or Block rank for its color. The quarter, half, three-quarter, and full silhouettes progressively fill the body regions protected by that armor. These combat and armor icons always precede non-combat skills.

An exact non-combat skill appears in the summary at healthy rank 3 or higher. Expandable families remain one icon: Social and context-free Terrain use their means, Oral and Written languages use their strongest effective language and that language's displayed identity, Religion uses the same contextual primary tradition (or strongest-effective fallback) as its rail, and Bestiary uses its aggregate effective coverage. Family tooltips list only qualifying leaves and their exact ranks. Standalone skills use their own icon and rank. The visible color is supplementary: every icon exposes its identity and score through the shared instant tooltip and accessible name.

The main difference between this and directly allocating skill points is that if your character is convalescing or traveling they cannot train. Not all skills are equal though in terms of how much training time they need to be effective, they all have their own falloff curve. The number in parentheses next to a listed skill is its asymptotic training calibration; half that many effective hours produces rank 2.5. The rate of increase from training is lower the higher they get, providing an upper asymptote for skill rank.

Real training time is converted to effective learned hours by the governing aptitude:

training_multiplier = max(0, 1 + 0.5 * (aptitude - 2.5))

Thus aptitude 0/1/2.5/4/5 learns at 0×/0.25×/1×/1.75×/2.25×. An activity first conserves and divides its real-hour budget, then applies each target skill's multiplier. Healthy conditioned aptitude, before injury, determines both this multiplier and the maximum effective rank. Stored hours above a lowered cap remain latent and become effective again if aptitude returns. Effective gain that crosses or exceeds the cap is rejected exactly at the boundary and feeds one shared, saturating Mastery enjoyment morale source. Forty excess effective hours reaches about 63% of its four-point limit. All rejected gains in one logical interval are combined before saturation; the existing enjoyment first decays linearly through the interval, then the combined award refreshes it at the endpoint. It reaches zero after seven days without another award. Aptitude zero earns neither effective hours nor mastery morale.

The skill rail has three computed combat groups: Melee, Ranged, and Defense. They have no stored hours and are never used directly for a tactical check. Melee expands to Polearm, Axe, Bludgeon, Sword, and Knife; Ranged expands to Bow, Crossbow, Firearm, and Throw; Defense expands to Dodge, Block, Balance, and Will. Equipped weapon distributions determine the relevant weapon leaves. A shield gives Block full relevance; without one, the best-balanced equipped melee weapon gives Block a weight of 1 - balance. Combat Training and Raiding divide their conserved activity award deterministically across those relevance weights.

Every weapon stores a nine-field skill distribution. A halberd uses Polearm, Axe, and Bludgeon equally; a glaive uses Polearm and Sword; short swords and daggers use Sword and Knife; a hand axe uses Axe and Knife. An attack averages the complete leaf-skill checks using those weights, including each check's attributes and penalties. Knife means short weapons rather than only literal knives.

Intuitive vs Trained

This distinction applies only to correlated training. An intuitive target may benefit from correlated hours without formal training in that target. A trained target evaluates to zero until it has target-specific direct hours, regardless of correlated knowledge. Correlation is derived in one pass, never stored, and never produces mastery morale. Physiology, Anatomy, Religion and Bestiary leaves, and Written languages are trained; Oral languages are intuitive.

Ordinary skill transfer uses a deliberately sparse symmetric matrix: Cooking and Knife transfer at 0.15; Sword and Knife, Dodge and Balance, and every pair of Terrain leaves transfer at 0.20. Only direct hours enter this one pass. A trained target receives at most as many transferred hours as it has direct hours: zero remains zero and an introductory lesson cannot unlock a lifetime of related experience all at once. Intuitive Terrain leaves do not use this direct-study cap. Skill rails show direct, correlated, and resulting effective hours separately in their tooltips. The meter's background extent is the uncapped rank projected from effective hours, including correlation; it is not a separate direct-hours layer. The brighter foreground remains the aptitude- and injury-limited effective check.

Each skill is represented in the stats window with its uncapped rank projected from effective hours (direct plus correlated) behind its current aptitude- and injury-limited rank. Hover text reports the direct hours, correlated contribution, resulting effective hours, and governing aptitude. Penalties such as encumbrance, armor, or injuries reduce only the current effective portion.

Mental

Will (intuitive, 5000 hours)

Ability to resist pain or avoid morale penalties. 0. Generalized anxiety disorder / panic disorder

1. Coward
2. Cautious, sensitive to pain
3. Professional soldier
4. Brave hero
5. Zen monk

Social skills (intuitive)

There's no persuasion system or anything for the MVP, this is primarily a morale and relationship system. All current Social leaves are governed by Instinct.

Insight reads others and oneself, Charm powers both humor and compatible flirtation, Command rallies and coordinates, and Deception sustains false impressions. Joke and Flirt remain separate morale actions: Grave actors cannot Joke and Proper actors cannot Flirt, while each of those reserved traits adds 0.35 to Rally Command. Party Command is led by the strongest individual check. Additional members receive a saturating coordination benefit, then contribute half of their deviation from a 2.5 baseline. Checks above 2.5 help and checks below 2.5 burden the party's social leadership. The result is capped from 0 to 5; adding arbitrarily many low-Command members cannot manufacture a high result. Character sheets summarize these four skills with an expandable Social meta-skill whose rank is their average.

0. Autistic
1. Cold and aloof
2. Boring
3. Friendly
4. Funny
5. Professional bard

Physiology (trained, 10000 hours)

Physiology governs what a particular character can discern about illness. Observation is passive while characters share a party and location; there is no separate examination action. The observer's individual capability band sets notebook cadence, symptom recognition, localization, confidence, and awareness of interventions. When capability crosses a band boundary, a new presence span begins so earlier notes retain the capability that produced them. Cuts and blunt trauma remain visible without Physiology; private meter causes are disclosed only through the deliberately many-to-one four-humour projection. The chart never names a disease or recommends a treatment.

Characters may explicitly administer a preparation they possess, choosing its amount and optional canonical body region through the preparation's supported route, or stop an active administration. These actions operate on generic, versioned physiology profiles rather than disease-keyed cures.

Physiology uses a bounded party-check equation. Individual checks are sorted strongest-first, the leader receives full weight, and successive contributors receive weights of 1/2, 1/4, 1/8, and so on:

[ P = 5\left(1-\prod_{i=1}^{n}\left(1-\frac{x_i}{5}\right)^{(1/2)^{i-1}}\right) ]

A solo character retains their exact individual check. The result never exceeds 5 and needs no final clamp. Because all supporting weights together equal the leader's weight, arbitrarily many equally skilled supporters can add at most the influence of one additional copy of the leader: Physiology 1 approaches 1.8, Physiology 2 approaches 3.2, Physiology 3 approaches 4.2, and Physiology 4 approaches 4.8.

0. Provides no help to anyone injured
1. Knows to disinfect wounds with alcohol
2. Can treat common diseases (flu/cold)
3. Can treat some organ damage and uncommon diseases
4. Can treat most organ damage and rare diseases
5. Can treat all organ damage and all diseases

Religion (trained, 5000 hours per tradition)

Religion represents knowledge, not conviction. It includes Roman Catholicism, Lutheranism, Reformed Christianity, Anglicanism, Eastern Orthodoxy, Islam, and Judaism. Canonical state records only hours learned in each tradition. Effective hours for a tradition are derived once by multiplying those hours by the symmetric correlation matrix; derived hours are never stored or recursively correlated. Prayer activity teaches the character's professed tradition. The skill rail can expand a primary tradition to show other traditions with nonzero direct knowledge, and each meter's hover text reports effective and directly learned hours.

The diagonal is 1.0. The upper-triangle correlations in stable order (Roman Catholic, Lutheran, Reformed, Anglican, Eastern Orthodox, Islam, Judaism) are: RC to the remaining traditions 0.80, 0.75, 0.80, 0.65, 0.10, 0.10; Lutheran 0.90, 0.85, 0.50, 0.10, 0.10; Reformed 0.85, 0.45, 0.10, 0.10; Anglican 0.55, 0.10, 0.10; Eastern Orthodox 0.15, 0.10; and Islam to Judaism 0.35.

A party's check for a particular religion includes every living member's effective knowledge of that tradition, regardless of what they personally profess. This permits a knowledgeable nonbeliever or member of another religion to lead prayers and sermons. The generic recruitment summary uses the character's maximum effective Religion check as a UI-only measure of coverage; authoritative morale and prayer always select the relevant tradition.

Conviction lives on the personality axis instead: Zealous contributes 5.0 pressure, Neutral 2.5, and Irreverent 0.0. A profession and conviction are separate; an Irreverent character may still officially profess a religion.

Bestiary (trained, 5000 hours per category)

Bestiary is a meta-skill, following the Religion model, whose leaf skills represent learned physical knowledge of Beast, Undead, Human, Werekin, Elf, Dwarf, Fey, Spirit, Greenskin, Insectoid, Draconid, Construct, and Wildmen creatures. A creature has one main type and may have several secondary types. Skeletons and ghouls are primarily Undead with Human as a secondary anatomical type; werewolves are primarily Werekin with Human and Beast secondary types. One evidence result always evaluates exactly one category. Transformed animal tracks can support Werekin without identifying whether the host is Human, Elf, or Dwarf.

Direct category hours are canonical. Effective hours use one symmetric, nonrecursive correlation pass after the target category has received direct study. Wildmen knowledge correlates strongly with Human knowledge and more modestly with Fey knowledge. The expandable skill rail shows effective and directly studied hours for every category with transferred knowledge. The parent Bestiary value is the mean effective coverage across every category, not the character's single best category. A question-mark cursor marks category icons as inspectable. Their hover/focus tooltips separate creatures for which the category is the main type from creatures for which it is a secondary type, and clicking pins the tooltip. Hovering or focusing an enemy type then shows only strengths and weaknesses derived from mechanics currently consumed by combat. Each strength appears on its own green line and each weakness on its own red line; no category-wide generalizations or unimplemented folklore are shown.

Against a creature, the attacker averages the Bestiary checks for every category on that creature. Excess-accuracy damage is capped at 2× plus that average check (up to 7×); even an untrained character retains the ordinary 2× head-and-throat cap.

Physical evidence first requires its ordinary inspection check. The inspecting character then makes hidden category-specific Bestiary checks for relevant authored implications. One canonical record keeps the original physical observation. Returning after later study may add newly recognized categories, but never removes or duplicates an existing result. Results also remain in the investigation journal after leaving the evidence site. No scheduled Bestiary training activity is currently implemented.

Physical

Polearm, Axe, Bludgeon, Sword, and Knife (intuitive, 8000 hours)

These are the five melee weapon leaves. Their fixed training aptitude is the average healthy Agility of both arms. Hybrid weapons use a weighted average of all tagged leaves. Knife covers short weapons, including daggers, short swords, hand axes, and compact butchery tools.

0. Has never been shown how to use a weapon or observed for an extended period of time
1. Can split firewood with an axe, zombies
2. Peasant levy, orcs, goblins
3. Professional soldier
4. Knight
5. Elven warrior

Bow, Crossbow, Firearm, and Throw (intuitive, 15000 hours)

These are the four ranged weapon leaves. Their fixed training aptitude is the average healthy Agility of both arms. Input precision remains a future client-to-combat signal, while weapon accuracy remains an equipment statistic; neither is a character attribute. Hybrid or throwable weapons may use more than one leaf.

0. Never practiced even throwing a baseball
1. Orcs, untrained peasants
2. Goblins, militia
3. Professional soldiers
4. Huntsmen
5. Elf rangers

Dodge (intuitive, 20000 hours)

0. Zombies
1. Drunk or very old people, orcs
2. Peasant levy, goblins
3. Professional soldier
4. Knight
5. Elven warrior

Block (intuitive, 12000 hours)

The larger your shield is, the less you rely on your block skill to use it effectively. A pavise requires almost none (though considerable strength), a buckler or weapon require high skill to use effectively.

0. Never been in a fight
1. Has been in some barfights
2. Fresh recruit
3. Professional soldier
4. Knights, heroes
5. Elven swordmasters

Stealth (intuitive, 8000 hours)

Stealth uses the average healthy Agility of all four limbs for training speed and mastery. Injury still penalizes current performance.

0. Has never even attempted to steal cookies from the cookie jar
1. Most people
2. Can tiptoe around the house in socks without waking anyone, usually
3. Novice hunter, professional mercenary trained in ambush tactics
4. Practiced thief, veteran hunter
5. Master thief, elven hunter

Balance (intuitive, 30000 hours)

Relevant for poise in melee. Strategic terrain speed is handled by the separate Terrain meta-skill and does not stack with Balance.

0. Cannot walk upright
1. Bit of a klutz, orcs
2. Can walk in high-heels, can dance in normal shoes, professional soldier
3. Can run and dance in high heels, amateur gymnast
4. Skilled gymnast or martial artist, can walk a tightrope
5. Graceful elf

Anatomy (mental, trained, 10000 hours)

Anatomy represents trained knowledge of bodies and wounds. Intelligence governs its training speed and mastery cap, while head injury remains a performance penalty. Herbalist apprenticeship and practice divide their training between Physiology (one half) and Anatomy, Knife, and Tailoring (one sixth each).

Surgery is a procedure, not a skill. Projectile extraction averages the treating character's Anatomy and Knife checks; stitching averages Anatomy and Tailoring. Bandaging and splinting use Anatomy alone. Self-treatment applies the shared 2.5-point penalty after the applicable skills are combined.

The recruitment rail's general Surgery coverage is the lower of the extraction and stitching checks. A specialist therefore cannot appear able to perform both procedures merely because their unrelated third skill is high.

Terrain (computed meta-skill; intuitive subskills, 30000 hours each)

Terrain stores no hours of its own. Its expandable subskills are Plains, Forest, Hills, Wetlands, and Urban. Each is an intuitive, Intelligence-governed mental skill. A route cell supplies a normalized mixture, and the displayed route/local Terrain value is the weighted combination of those subskills; without context the character rail shows their unweighted mean. Urban is stored and displayed now but has zero routing weight until the world pipeline has an authoritative urban-coverage source. Roads exercise the underlying terrain rather than Urban and reduce training in proportion to the time they save.

Tailoring (trained, 10000 hours)

Tailoring makes and repairs cloth goods. Settlement tailors and field maintenance use it for clothing durability, and stitching combines it with Anatomy.

Smithing (trained, 10000 hours)

Smithing makes and repairs weapons, armor, and shields. It does not repair clothing.

Languages

Oral and Written are expandable skill families rather than generic leaf Skill values. Oral includes East-central, West-central, Low, Yiddish, Latin, Romani, Elven, and Dwarfish; Written includes German chancery, Low, Latin, Hebrew, Yiddish, Elven, and Dwarfish. Direct hours are authoritative. Effective hours are a one-pass symmetric correlation, following the Religion model. A pair uses the language with the highest shared coefficient, with stable enum order breaking ties.
