# Vagabond RPG Foundry VTT System - Development Context
## Project Overview
This is a complete Foundry VTT v13 system implementation for Vagabond RPG (Pulp Fantasy TTRPG).
## Key Architecture Decisions
### Data Models (Foundry v13 style)
- Use TypeDataModel classes in `module/data/` for Actor and Item schemas
- Character stats: Might, Dexterity, Awareness, Reason, Presence, Luck (range 2-7)
- Derived values calculated in `prepareData()`: HP, Speed, Save difficulties, Skill difficulties
### Roll System
- Base formula: d20 >= (20 - Stat) for untrained, d20 >= (20 - Stat*2) for trained
- Favor: +d6 bonus die
- Hinder: -d6 penalty die
- Crit: Natural 20 by default, but threshold can be modified per-skill by Active Effects
- Exploding dice: d6! notation for certain abilities
### Spell Casting
- Dynamic mana cost = base + delivery cost + duration cost + extra damage dice
- Delivery types: Touch(0), Remote(0), Imbue(0), Cube(1), Aura(2), Cone(2), Glyph(2), Line(2), Sphere(2)
- Duration: Instant (free), Focus (ongoing), Continual (permanent)
- Cast dialog must calculate and display total mana cost before casting
### Class System
- Classes are Items with progression tables
- When dragged to character, creates Active Effects for current level
- On level up, update Active Effects to grant new features
- Supports future multiclassing by allowing multiple class items
### Crit Threshold System
- Each skill/action has a `critThreshold` field (default 20)
- Active Effects from classes/perks can modify: `system.skills.melee.critThreshold`
- Fighter's Valor reduces crit by 1/2/3 at levels 1/4/8
- Gunslinger's Deadeye dynamically reduces on consecutive hits
### Resources
- HP: max = Might * Level
- Mana: class-dependent, max from class progression
- Luck: equals Luck stat, refreshes on rest
- Fatigue: 0-5, death at 5, each reduces item slots by 1
- Studied Dice: some classes grant these
- Custom resources can be added dynamically
## File Naming Conventions
- Main system entry: `vagabond.mjs`
- Document classes: `VagabondActor.mjs`, `VagabondItem.mjs`
- Sheet classes: `VagabondCharacterSheet.mjs`, `VagabondNPCSheet.mjs`
- Data models: `CharacterData.mjs`, `NPCData.mjs`, `SpellData.mjs`, etc.
- Templates: `character-sheet.hbs`, `npc-sheet.hbs`, `spell-item.hbs`
## Testing Commands
```bash
# Start local Foundry
docker compose up -d
# Watch SCSS
npm run watch
# View logs
docker compose logs -f foundry
```
## Reference Data Location

- `core-mechanics.md` - Stats, checks, dice, HP
- `combat.md` - Actions, movement, defending, zones
- `character-creation.md` - Ancestries, classes, leveling
- `magic-system.md` - Casting, mana, delivery, duration
- `spells-full-text.md` - All 55+ spells with full descriptions

## Project Roadmap
See `PROJECT_ROADMAP.json` for complete task breakdown with dependencies.
## Style Guidelines
- Parchment color scheme with high contrast (WCAG AA compliant)
- Match official Hero Record layout where possible
- Use CSS custom properties for theming
- SCSS with BEM naming convention
