# Sub-Task 10 Progress: Essence Refining Investigation

## Status: Completed

## Completed Steps
- [x] Locate Essence Refining effect logic
- [x] List all enchantment types in the game
- [x] Test Essence Refining on each enchantment type
- [x] Document compatible/incompatible types
- [x] Fix or flag incompatible cases
- [x] Write findings to essence_refining_findings.md
- [x] Commit and push changes

## Summary of Findings
**Bug 15 Confirmed**: The `Essence Refining` skill and all `enchantPower` perks are NOT WORKING.

### Root Cause
1. `enchantPower` stat is set by skills/perks but never stored in `ComputedEffects`
2. `enchantPower` multiplier is never applied to enchantment effects in `computeEquipmentEffects()`

### Enchantment Type Compatibility
| Category | Effect Type | Compatible with Essence Refining | Notes |
|----------|-------------|----------------------------------|-------|
| Spell | `spell` | NO | Grants spell access, no numeric values |
| Mana | `bonus` | YES | +50 mana, +1 regen, etc. should be multiplied |
| Combat | `bonus`, `multiplier` | YES | +5 damage, +10% damage, etc. should be scaled |
| Elemental | `special` | PARTIAL | Special effects need separate handling |
| Defense | (empty) | N/A | No effects defined |
| Utility | `multiplier` | YES | +10% study speed, etc. should be scaled |
| Special | `special`, `multiplier` | PARTIAL | `guardianDamage` can be scaled, pure specials cannot |

### Files to Fix
1. `/src/lib/game/upgrade-effects.ts` - Add `enchantPower` to `ComputedEffects` and handle in `computeEffects()`
2. `/src/lib/game/effects.ts` - Apply `enchantPower` multiplier to equipment effects

### Next Steps
The findings have been documented in `essence_refining_findings.md`. A developer should implement the fix by:
1. Adding `enchantPower: number` to `ComputedEffects` interface
2. Handling `enchantPower` case in `computeEffects()` switch statement
3. Applying `enchantPower` multiplier in `computeEquipmentEffects()`

## Notes
- Finding date: 2025-01-16
- Bug verified by code inspection
- No runtime testing needed - the code clearly doesn't apply the multiplier
