| `saveSkill` | `string` | `''` | e.g. `'reflex'`, `'determination'` |
| `overcastOptions` | `array of {description, manaPerStep}` | `[]` | Replace free-text `overcasting` with structured list (legacy field kept for migration) |
| `sourceBook` | `string` | `''` | `'kg-magii'` / `'crimson-cult'` / `'abyss-curse'` / `'arcanum-sanguinis'` / `'core-rules'` |
| `castingTimeRounds` | `number` | `0` | 0 = action; >0 = rounds (used for combat enforcement of long casts) |
| `castingTimeMinutes` | `number` | `0` | For non-combat scaling (rituals, superspells) |
| `triggers` | `array of {event, effect}` | `[]` | Reactive effects: `{event:'killWithWeapon', effect:'freeCrimsonSpell'}`, `{event:'targetCastsSpell', effect:'forceUnconscious'}` |
| `variableSuccesses` | `array of {label, successes}` | `[]` | For Przywołanie Istoty z Otchłani: `[{label:'Tajemny Krab', successes:2}, ...]` |

### 5.3 Backward compatibility / migration

- Keep legacy fields (`overcasting`, `complexityLevel`, `targets`) populated for one minor version.
- Migration script in `src/migrations/0.2.0.ts`:
  - Move `complexityLevel` count → ensure `components.symbols.length` matches; if symbols empty, leave count.
  - Best-effort parse of `targets` string → `areaOfEffect` (regex: `/(\d+)\s*[×x]\s*(\d+)/`, `/promień\s+(\d+)/`).
  - `overcasting` text → seed first entry of `overcastOptions[0].description`.

## 6. Casting Logic - Gap Analysis

> Reference: [.src/foundry-system/src/logic/spell-cast.ts](../.src/foundry-system/src/logic/spell-cast.ts)

### 6.1 Pre-cast validation gates (new)

```
function validateCast(actor, spell, opts) -> ValidationResult
  - resourceCheck (mana / zeal / blood / mana+zeal for Hekate)
  - raceCheck (spell.requirements.race)
  - talentCheck (spell.requirements.talent - items on actor)
  - disciplineCheck (spell.requirements.discipline - at least one match)
  - deityCheck (sacred + non-empty deity → actor must be devoted to that deity)
  - groupCastCheck (warn if requiresGroupCast and only 1 caster targeted)
  - inCombatCheck for nonCombatOnly → block (warn-only override flag in opts)
  - inCombatCheck for isSuperspell → WARN (do not block); bypass via opts.bypassSuperspellWarning
  - witchSymbolCheck (count <= ceil(magic/2)) - already exists
```

### 6.2 New CastOptions

```ts
interface CastOptions {
  manaSpent?: number;
  zealSpent?: number;            // for Hekate when cast as sacred
  bloodSpent?: number;           // for blood mode
  hekateMode?: 'sacred' | 'witch'; // Hekate spell dispatch
  bypassSuperspellWarning?: boolean;  // Downcasting talent, NPC quick-cast abilities
  bypassNonCombatBlock?: boolean;     // GM override
  groupCasters?: string[];       // actor IDs of co-casters
  speaker?: ChatMessage.SpeakerData;
}
```

### 6.3 New casting modes

#### `castBlood(actor, spell, opts)`
- Resource: deduct `spell.bloodCost` from `actor.system.attributes.blood.value` (new attribute on character data - or HP if blood pool not added)
- Pool: `magic + magicalAbilities` (placeholder; final formula TBD when Blood Magic spells released)
- No overcast for v1; revisit when content lands

#### `castSacred` extension
- If spell has `complexityLevel > 0` (Hekate), allow `opts.hekateMode === 'witch'` to dispatch to `castWitch` instead

### 6.4 Damage rolling integration

Currently `castSpell` only rolls the TS test - no damage application. Add:

```
function rollSpellDamage(actor, spell): Roll
  - parse spell.damageBase formula
  - resolve tokens: 'magicalAbilities', 'devotion', 'soul', '1d6', etc.
  - return Roll for chat output
```

Display side-by-side in chat card: TS result | Damage formula result | Status effects to apply | Save target attribute+skill.

### 6.5 Status effect auto-apply

When TS test succeeds AND target has lower successes on save:
- For each entry in `spell.statusEffects[]`, apply ActiveEffect via Foundry condition system
- Hook into `conditions.ts` (already exists for combat status tracking)

### 6.6 Trigger registration

For reactive spells (Szkarłatny Sztylet, Klątwa Szkarłatu):
- On successful cast → register a hook on actor (`flag.hbm-rpg-v3.triggers[]`)
- Hook fires on matching combat event (`'killWithWeapon'` → free spell prompt; `'targetCastsSpell'` → opposed Determination test)
- Triggers expire on duration end or single use

### 6.7 Variable success summons

For Przywołanie Istoty z Otchłani:
- Cast UI prompts user to pick which entity (Tajemny Krab / Strażnik / Czempion / Simulacrum)
- Required successes loaded from `spell.variableSuccesses[selected].successes`
- Pass into TS test as `required` override

### 6.8 Group cast orchestration

For Zagłada:
- Cast UI lists co-casters from `opts.groupCasters[]`
- Each contributes their dice pool (sum)
- On success, all participants take "death" status (per spell description)
- Pre-cast warning chat card requires GM confirm

## 8. Character Sheet Spell Tab - Enhancement Spec

> Reference: [.src/foundry-system/src/sheets/character-sheet.ts](../.src/foundry-system/src/sheets/character-sheet.ts)

### 8.1 Grouping & filtering

- Replace flat `spells` list with grouped structure in `_prepareContext`:
  ```ts
  spellsByDiscipline: Record<DisciplineId, Item[]>
  spellsBySchool: Record<School, Item[]>
  superspells: Item[]  // separate list pulled out
  ```
- Sidebar filter UI: by `school`, `castingMode`, `deity`, `circle`, search-by-name
- Persist filter in `tabGroups['spellsFilter']`

### 8.2 Per-row badges

| Badge | Source field |
|---|---|
| Casting mode icon | `system.castingMode` (4 icons: ✦ standard, ✟ sacred, ✶ witch, ❤ blood) |
| Source book pip | `system.sourceBook` (color-coded) |
| Deity label | `system.deity` (only for sacred) |
| Superspell star | `system.isSuperspell === true` |
| Race-locked badge | `system.requirements.race.length > 0` |

### 8.3 Cast button enhancements

- Greyed out + tooltip when `validateCast()` fails (race/talent/discipline missing)
- Yellow warning icon when superspell + actor in combat
- Click → opens enhanced cast dialog with mana/zeal/blood field, hekate-mode toggle, group-caster picker, bypass-warning checkbox (GM only)

### 8.4 Resource displays

Add to stats tab header:
- Mana / max-per-spell / per-round (existing)
- **Blood pool** (new, only if any spell with `castingMode: 'blood'` is owned)
- Zeal (existing)

---

## 9. Spell Item Sheet - Enhancement Spec

> Reference: [.src/foundry-system/templates/item/spell.hbs](../.src/foundry-system/templates/item/spell.hbs)

### 9.1 Add fieldsets (in order)

1. **Identyfikacja** - name, sourceBook (select), school (select), discipline (select), deity (conditional select if school=sacred), circle
2. **Tryb rzucania** - castingMode (select), bloodCost (if blood), components.symbols (tag picker against `WITCH_SYMBOLS`, free-text allowed)
3. **Trudność** - threshold, successes, manaCost, castingTimeRounds, castingTimeMinutes
4. **Zasięg & Obszar** - range, areaOfEffect (shape select + x/y inputs), targets (kept as freetext fallback)
5. **Czas trwania** - duration, nonCombatOnly (checkbox)
6. **Obrażenia** - damageBase (text), damageType (select), ignoresArmor (checkbox)
7. **Efekty statusu** - statusEffects (multi-select against `CONDITIONS`), saveAttribute + saveSkill
8. **Wymagania** - requirements.race (multi-select), .talent (multi-select), .discipline (multi-select)
9. **Flagi** - isSuperspell, requiresGroupCast, minCasters
10. **Nadczarowanie** - repeatable list of `overcastOptions[]` (description + manaPerStep)
11. **Wyzwalacze (Triggery)** - repeatable list of `triggers[]` (event select + effect text)
12. **Warianty sukcesu** - repeatable list of `variableSuccesses[]` (label + successes)
13. **Opis & komponenty fabularne** - description (HTML), higherCircles (HTML, deprecated → migrated to overcastOptions)

### 9.2 Conditional rendering (Handlebars)

- Deity select: only if `system.school === 'sacred'`
- Blood cost: only if `system.castingMode === 'blood'`
- Witch complexity / symbols: if `castingMode === 'witch'` OR Hekate sacred spell
- Variable successes: only if non-empty (collapsible)
- Triggers: only if non-empty (collapsible)

### 10.2 Generation pipeline

- Source: structured YAML/JSON in `.src/foundry-system/data/spells/*.yaml` (one file per discipline)
- Build script (`scripts/build-packs.ts`) reads YAML, validates against Zod schema mirroring `SpellData`, writes LevelDB pack files into `packs/`
- Run as part of `bun run package`

---

## 11. Implementation Phases

### Phase A - Data model expansion (no UI changes)
1. Extend `SpellData` schema with all fields from §5.2
2. Add constants from §7
3. Write migration `0.2.0` for existing world data
4. Bump version → 0.2.0

### Phase B - Compendium seeding
1. Build YAML source files for all ~93 spells (§4) under `.src/foundry-system/data/spells/`
2. Implement `scripts/build-packs.ts`
3. Wire `bun run package` to generate packs

### Phase C - Casting logic upgrade
1. `validateCast()` pre-cast gates (§6.1)
2. New `castBlood()` mode + extend `CastOptions` (§6.2-6.3)
3. `rollSpellDamage()` + chat card overhaul (§6.4)
4. Status effect auto-apply hook (§6.5)
5. Trigger registration system (§6.6)
6. Variable success / group cast UI (§6.7-6.8)

### Phase D - Sheet UX
1. Spell item sheet enhancements (§9)
2. Character sheet spell tab grouping/filtering (§8)
3. Cast dialog overhaul

### Phase E - Quality & polish
1. Localization keys (Polish + English) for all new fields
2. CSS for badges, condition icons, source book pips
3. Foundry compendium browser metadata (image, system tags)

---

## Appendix A - Spell Field Naming Convention

- IDs: `kebab-case` matching slug-of-name (English-translated where idiomatic, Polish-derived otherwise)
- All UI labels: localized via `lang/pl.json` & `lang/en.json` keys under `HBM.spell.*`
- Damage formulas: lowercase camelCase tokens (`magicalAbilities`, `devotion`, `soul`, `mind`, `body`, `magic`)
- Conditions: lowercase singular (`stunned`, `prone`, `frightened`)

## Appendix B - Outstanding Questions

1. **Blood Pool resource**: should `actor.system.attributes.blood` be a new dedicated pool, or does Magia Krwi simply consume HP? Pending Arcanum Sanguinis spell list.
2. **Hekate "hybrid" persistence**: when cast as witch, should the spell consume zeal *or* mana? Currently planned: choose one per cast via `opts.hekateMode`.
3. **Detect Changes (`detect-changes`)**: spell explicitly says "no overcast"; need a `noOvercast: boolean` flag, OR encode in `overcastOptions: []` (empty = no overcast).
4. **Status effect saves**: which spells require an opposed Magia/Zdolności Magiczne test vs target's `saveAttribute + saveSkill`, and which auto-apply on TS success? Each spell needs explicit annotation in compendium YAML.
5. **Dzika Wiedźmia Magia** spells: not enumerated separately in books; mostly variants of standard witch magic with chaos overlay. Defer to dedicated content drop.
