+- [x] Review Sub-Task 8 completion (get conversion drain data)
+- [x] Design mana breakdown UI for StatsTab
+- [x] Implement data fetching for each mana type's stats
+- [x] Add modifiers display (attunements, conversion drains)
+- [x] Test reactive updates
+- [x] Commit and push changes

+## Implementation Details
+
+### Files Modified
+1. **src/components/game/stats/ManaTypeBreakdown.tsx** (NEW)
+   - Created new component to display detailed breakdown for each mana type
+   - Shows current value, capacity, and effective regen rate
+   - Lists modifiers: attunement bonuses, conversion drains from Sub-Task 8
+   - Groups elements by category (base, composite, exotic, utility)
+   - Shows recipe for composite/exotic elements
+   - Includes progress bars for visual clarity
+
+2. **src/components/game/tabs/StatsTab.tsx** (MODIFIED)
+   - Added import for ManaTypeBreakdown component
+   - Added ManaTypeBreakdown section after ManaStatsSection
+
+### Features Implemented
+- Raw Mana section with:
+  - Current/max display
+  - Progress bar with color coding
+  - Base regen, conversion drain, effective regen
+  - Per-attunement conversion drain breakdown
+
+- Elemental Mana sections (for each unlocked element):
+  - Current/max display with element-specific colors
+  - Progress bar with element color
+  - Conversion rate from attunements
+  - Source attunement names and levels
+  - Recipe display for composite/exotic elements
+
+### Testing
+- `npm run build` completed successfully with no errors
+- Component uses reactive data from store
+- Properly handles conversion drains from Sub-Task 8
 
 ## Notes
-(Add UI design notes here)
+- Uses `computeEffectiveRegenForDisplay` from mana-utils.ts for regen calculations
+- Uses `getAttunementConversionRate` from attunements.ts for per-attunement drain
+- Conversion drains are read from `store.conversionDrains` (populated by Sub-Task 8)
+- Element categories (base, composite, exotic, utility) are preserved from ELEMENTS constant
