# Sub-Task 10: Essence Refining Investigation (Bug 15)

## Scope
- **Core files to investigate**:
  - Essence Refining effect logic (e.g., `effects/essenceRefining.ts` or similar)
  - All enchantment type definitions (e.g., `data/enchantments.ts`, `types/enchantments.ts`)
  - Enchantment application logic (to check compatibility)
- **Files potentially affected**:
  - Any enchantment type that Essence Refining cannot apply to (fix or flag)
  - Documentation for Essence Refining effect

## Acceptance Criteria
1. Verify Essence Refining effect works across all enchantment types
2. Document which enchantment types it cannot apply to (e.g., spell enchantments)
3. Either:
   - Fix cases where it should apply but doesn't, OR
   - Flag out-of-scope cases with clear explanation
4. Write findings to `docs/task3/essence_refining_findings.md`

## Dependencies
- None (independent investigation task)

## Estimated Complexity
- Medium (testing multiple enchantment types + documentation)
