Every system in the actor.rpg.stats record lives under its own top-level key — a single record can hold D&D, Cyberpunk 2020, Mage, and RPG Maker stats at the same time, without conflict. You only implement the fields you need.

This reference covers the field-level structure of every built-in system. All fields are optional unless noted. The schema is designed for forward compatibility — unknown fields are preserved on read, partial records are valid, and new systems are added without breaking existing data.

If you're building a game and want to use one of these systems, or add your own, see the Game Systems section in the Developer Guide.

Raw lexicon files are available for direct integration:

• actor.rpg.stats.json — full schema (55 definitions)

D&D 5e is the most fully-featured system in the schema. It covers the complete official character sheet across a set of independent sub-objects — you can include only the parts your game actually uses. A record containing nothing but abilities and hp is perfectly valid; there's no obligation to store spell slots just because you have a combat block.

Sub-objects are stored under nested keys within stats.dnd. Ability modifiers and skill modifiers are not stored directly — the UI calculates them from the raw scores and proficiency bonus at read time.

Identity dnd.identity

Abilities dnd.abilities

All six core ability scores. Modifiers are calculated by the UI (floor((score − 10) / 2)).

Hit Points dnd.hp

Combat dnd.combat

Conditions dnd.conditions

Saving Throws dnd.saves

Each field stores the total modifier (ability mod + proficiency, as applicable). Values are integers and can be negative.

Skills dnd.skills

All 18 skills store the total modifier (integer, can be negative). Half-proficiency, expertise, and jack-of-all-trades bonuses should be baked in before saving.

Passives dnd.passives

Attacks dnd.attacks

An array of attack entries (max 20). Each object:

Equipment dnd.equipment

Coinage dnd.coinage

Personality dnd.personality

Text Fields dnd.*

Spellcasting dnd.spellcasting

DCC has the most specialized schema in the collection — deed dice, mercurial magic, spellburn, a 0-level funnel, and probabilistic thief skills that scale with level rather than proficiency. It reflects a deliberately different mechanical philosophy from 5e.

Level 0 funnel characters are fully supported — identity.level starts at 0. Class feature blocks are conditional: populate only the block matching your character's class, and the sheet renderer will show only that section.

Identity dcc.identity

Abilities dcc.abilities

DCC uses its own modifier table (3=−3, 4–5=−2, 6–8=−1, 9–12=0, 13–15=+1, 16–17=+2, 18–24=+3), not the 5e formula. Modifiers are calculated by the UI. The *Base fields track pre-spellburn values so spellburn can be recovered incrementally.

Luck dcc.luck

Hit Points dcc.hp

Combat dcc.combat

Saving Throws dcc.saves

Attacks dcc.attacks

Array of weapon attacks (max 10). Each entry:

Class Sections (conditional)

Only populate the block matching the character's class. The sheet renders each section only when identity.class matches the relevant class name, or when the block already contains data. Setting data in a class block without a matching class name will still display.

Warrior / Dwarf  dcc.warrior

Wizard / Elf  dcc.wizard

Cleric  dcc.cleric

Thief  dcc.thief

Thief skills store the raw die modifier for a d20 roll — e.g. +3 means roll d20+3 against a static target number. This is not a 5e DC system; the modifier scales as the thief levels up.

Halfling  dcc.halfling

Equipment & Coinage dcc.equipment / dcc.coinage

Text Fields dcc.*

A full Cyberpunk 2020 sheet for Night City operators. It covers all nine STAT scores, every skill across the attribute groups, the wound track by severity level, armor by hit location zone, weapons, a ten-slot cyberware roster, and a notes field.

Stats are stored as integers (0–10). Humanity is a string rather than an integer to support the current/base format common in CP2020 sheets (e.g. "38/40"). Skills that derive from an attribute base display as a ratio in the UI but are stored independently.

Identity & Derived cyberpunk2020.*

Stats cyberpunk2020.* (0–10 each)

Role Ability cyberpunk2020.roleSkill1

Skills cyberpunk2020.* (all integer 0–10)

Combat cyberpunk2020.*

Cyberware & Notes cyberpunk2020.*

A complete Mage: The Ascension (Revised/WoD) sheet. This is the World of Darkness version — Arete to 10, Quintessence and Paradox on a shared 20-step wheel, Willpower with separate permanent (dots) and temporary (squares) tracks, and all nine Spheres.

Attributes, Abilities, and Sphere ratings all use the standard 1–5 dot scale. Health is stored as a filled-level count (0 = Unharmed, 7 = Incapacitated) rather than individual box states. Backgrounds and Traits use named slot objects with a label and dot value.

Identity mage.*

Attributes mage.* (all integer 0–5)

Abilities mage.* (all integer 0–5)

Spheres mage.* (all integer 0–5)

Backgrounds & Traits mage.*

Named dot-rated entries. Each stored as { title: string(50), value: integer 0–5 }.

Ratings & Pools mage.*

Experience & Notes mage.*

A complete Vampire: The Masquerade 5th Edition sheet. Attributes and Skills follow the standard three-category layout. Trackers — Health, Willpower, Humanity, Hunger, and Blood Potency — are stored as integer pip counts rather than sub-objects, which makes them easy to compare and do arithmetic on.

Disciplines use named slot objects, each holding a dot rating and up to five named Powers. Advantages (Backgrounds, Merits, Flaws) share a common { type, value } object structure across all their slot groups.

Identity vampire.*

Attributes vampire.* (all integer 0–5)

Skills vampire.* (all integer 0–5)

Morality vampire.*

Disciplines vampire.*

Trackers vampire.*

All tracker values are stored as integer pip counts (filled squares), not as sub-objects.

Blood Potency Details vampire.*

Text labels derived from the Blood Potency table. Store the label for the character's current potency level.

Advantages vampire.*

All advantage slots store { type: string(64), value: integer 0–5 } where type is the name of the background, merit, or flaw.

Haven vampire.*

Experience & Weapons vampire.*

Biography vampire.*

Maps directly to the standard RPG Maker MZ actor parameters (MHP, MMP, ATK, DEF, MAT, MDF, AGI, LUK), plus level, class name, XP, and current HP/MP/TP. Storing these in the player's PDS lets compatible games carry a character's progression forward across different sessions and titles without relying on local save files.

The character schema for Playtopia Quest — a lightweight social RPG where your class is how you move through the world, not what spells you have. Classes run from Artist to Weirdo. Alignment is chaos-adjacent. Your bestFriend and worstEnemy are stored as AT Protocol handles.

The spectrum system used by Reverie House. Rather than the traditional good/evil and law/chaos axes, Reverie positions a character across six philosophical dimensions. The combination of values determines an octant classification, which carries narrative meaning within that world.

Known octants: adaptive, chaotic, prepared, intended, contented, assertive, ordered, guarded, equilibrium, singling, confused

The original catch-all key from before dedicated system keys were added. The stats[] array accepts any named stat with an optional range and category grouping. It still works, but new integrations should use their own top-level key — the custom key is limited to a single system definition in one record.
