Cal Corum 6247004b58 Implement spell casting system with rulebook-accurate mana costs
- Add SpellCastDialog with delivery/duration/damage configuration
- Fix mana cost calculation to match rulebook formula:
  - Effect-only or 1d6 damage-only = 0 mana
  - Both damage AND effect = 1 mana base
  - +1 per extra damage die beyond first
  - +delivery cost (Touch/Remote/Imbue=0, Cube=1, Area=2)
  - Duration has no initial cost (Focus requires maintenance)
- Add "Include Effect" toggle for damage vs effect choice
- Create spell cast chat card template
- Add 20+ i18n strings for spell casting UI
- Create comprehensive Quench tests for mana calculation
- Add Cast Spell macro for testing
- Update CLAUDE.md with NoteDiscovery access instructions

# 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
**Casting Decisions:** When casting, determine Damage/Effect, Delivery, and Duration.
**Mana Cost Formula:**
1. **Base cost:**
- Only 1d6 damage OR only effect = 0 Mana
- Both damage AND effect = 1 Mana
2. **+ Extra damage dice:** +1 Mana per d6 beyond the first
3. **+ Delivery cost:** Touch(0), Remote(0), Imbue(0), Cube(1), Aura(2), Cone(2), Glyph(2), Line(2), Sphere(2)
4. **Duration:** Instant/Focus/Continual - no initial cost, but Focus requires 1 Mana/round to maintain on unwilling targets
**Cast Checks:** Only required when targeting an unwilling Being.
**Cast Skills by Class:** Wizard/Magus=Arcana, Druid/Luminary/Witch=Mysticism, Sorcerer=Influence, Revelator=Leadership
### 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
```
### Testing Code Revisions
```bash
# Restart local Foundry container
docker compose restart
```

## 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
