ACKS II — Full Monster Sheet

A Foundry VTT module that extends the ACKS II game system with a complete, structured Monstrous Manual stat block for monster actors.

It adds an alternate "ACKS Full Monster" sheet (you toggle it per-actor) and automation-ready storage for every primary, secondary, and encounter characteristic — types, size/mass, body form, multi-row speeds, per-attack damage types, spoils, proficiencies, lifespan, market values, and henchman/retainer data.

Storage only. This module stores the data; it doesn't compute derived stats, harvest spoils, or run taming. It reuses the system's own weapon / ability / item documents and leaves game logic to consumer modules, which read the stored fields and flags.

Design principle: reuse → extend → enhance → invent

• Reuse the core monster actor type and its fields (hp, AC, saves, morale, XP, alignment, treasure, retainer), its Items (attacks = weapon items, proficiencies & abilities = ability items, spoils = generic items), and its actor methods (roll HP / reaction / appearing).
• Extend only with genuinely-new fields, stored in flags["acks-monsters"].extras and typed by an in-memory DataModel (nullable numerics → a blank field is null, never 0).
• Enhance with a toggleable sheet, "Generate saves from HD", a "serve as henchman of…" helper, and an item-sheet metadata injector.
• Invent nothing that the system already provides.

No new document sub-type is created — the Full Monster sheet is a runtime subclass of the system's own monster sheet (inheriting its compact header, item/effect/save actions, Generate Saves, and CSS) registered as an alternate sheet on the existing monster type. It replaces the tab set with: Classification · Attacks · Abilities · Inventory · Defenses & Magic · Ecology · Henchman · Spells · Description · Effects. Attacks (weapon items), Abilities (ability items), and Inventory (item/armor) are separate lists; short enum sets (types, vision, damage) use native checkbox chips.

Requirements

• Foundry VTT v14+ and the ACKS II system (acks) v14+ (verified against 14.364).

Usage

1. Install the module (manifest below) and enable it in your world.
2. Open any monster actor → the header Sheet (⚙) → pick ACKS Full Monster. (Or right-click a monster in the sidebar → Open Full Monster Sheet.)
3. Fill in the tabbed stat block. Attacks/abilities/spoils are added as normal ACKS items; open a monster-owned weapon/ability/item to set its ACKS Monster metadata (damage type, ability category, spoil component/effects).
4. The example compendia ship 8 invented test monsters spanning the storage model — Giant Rat (small animal, swim row), Skeleton (undead+construct, defenses block), Dire Wolf (senses, war-mount values), Goblin + Chief (gear inventory, warband nouns, variant links), Pack Mule (carried gear vs Normal/Max Load — ships Encumbered on purpose), Ash Drake (breath weapon, innate spellcasting, immunity/susceptibility, fly, oviparous, hoard), and Marsh Lurker (HD range, multi-tentacle attacks, aquatic senses) — plus standalone spoils items and a blank treasure table. Stats are invented over generic open-content archetypes; nothing is reproduced from published books.

Henchmen

Monster actors carry the system's retainer fields, so the Henchman tab exposes enabled, category, loyalty, wage, quantity, and manager — plus the combat data a hireling needs. Because the core system's built-in addHenchman currently rejects non-character actors, use the "Serve as henchman of…" button: it sets the retainer fields and appends the monster to the chosen character's henchmenList directly.

Data model

See docs/MODEL.md for the full field↔stat-block storage map and the consumer API, and the local rules extract (acks-rules/acks-monsters/RULES.md) for the canonical ACKS II monster-rules extract behind the enumerations.

Development

npm install
npm run validate     # JS syntax, Handlebars templates, JSON
npm run build:packs  # compile the example compendia (LevelDB)

Compendium sources live in packs/_source/* (generated by tools/build-packs.mjs); the compiled LevelDB packs in packs/* are shipped in releases. Cut a release by pushing a vX.Y.Z tag matching module.json.
