+# Crafting & Equipment System Implementation Summary
+
+## Overview
+Replaced the combat skills system with a comprehensive equipment and enchantment system. Players now gain combat abilities through enchanted equipment rather than skills.
+
+## Completed Tasks
+
+### 1. Equipment System (✅ Complete)
+- **File**: `/src/lib/game/data/equipment.ts`
+- 8 equipment slots: mainHand, offHand, head, body, hands, feet, accessory1, accessory2
+- 20+ equipment types across categories: caster, shield, catalyst, head, body, hands, feet, accessory
+- Capacity system: Each equipment has base capacity for enchantments
+- Starting equipment: Basic Staff (with Mana Bolt), Civilian Shirt/Gloves/Shoes
+
+### 2. Enchantment Effects Catalogue (✅ Complete)
+- **File**: `/src/lib/game/data/enchantment-effects.ts`
+- 100+ enchantment effects across 7 categories:
+  - **Spell** (40+): Grant ability to cast specific spells
+  - **Mana** (20+): Capacity, regen, efficiency bonuses
+  - **Combat** (15+): Damage, crit, attack speed
+  - **Elemental** (10+): Elemental damage bonuses
+  - **Defense** (4): Damage reduction, mana shields
+  - **Utility** (8): Study speed, meditation, insight
+  - **Special** (12): Unique effects like echo, lifesteal, executioner
+
+### 3. Crafting Store Slice (✅ Complete)
+- **File**: `/src/lib/game/store/craftingSlice.ts`
+- Equipment instance management
+- Enchantment design workflow
+- Preparation progress tracking
+- Application progress with mana consumption
+- Helper functions for computing equipment effects
+
+### 4. CraftingTab UI Component (✅ Complete)
+- **File**: `/src/components/game/tabs/CraftingTab.tsx`
+- 4 sub-tabs: Equipment, Design, Enchant, Craft
+- Equipment slot visualization with rarity colors
+- Effect catalogue with capacity preview
+- Design creation workflow
+
+### 5. Type Definitions (✅ Complete)
+- **File**: `/src/lib/game/types.ts`
+- EquipmentInstance, AppliedEnchantment, EnchantmentDesign interfaces
+- Crafting progress states (DesignProgress, PreparationProgress, ApplicationProgress)
+
+### 6. Skill Evolution Cleanup (✅ Complete)
+- **File**: `/src/lib/game/skill-evolution.ts`
+- Removed combatTrain evolution path (orphaned - skill not in SKILLS_DEF)
+- Removed COMBAT_TRAIN upgrade definitions
+
+### 7. Bug Fixes (✅ Complete)
+- Fixed CraftingTab icon imports (Ring → Circle, HandMetal → Hand)
+
+## Remaining Tasks (Future Work)
+
+### 1. Equipment-Granted Spells in Combat (Medium Priority)
+- The `equipmentSpellStates` array exists but isn't fully utilized
+- Combat tick should check for equipment-granted spells
+- Multi-spell casting from different equipment pieces
+- Individual spell cooldown tracking
+
+### 2. SpellsTab Integration (Low Priority)
+- Add section showing equipment-granted spells
+- Indicate which equipment piece grants each spell
+- Distinguish between learned vs equipment-granted spells
+
+### 3. Evolution Paths for Crafting Skills (Low Priority)
+- Add evolution paths for existing crafting skills:
+  - `effCrafting` → Efficient Enchanter
+  - `durableConstruct` → Master Artisan
+  - `fieldRepair` → Field Engineer
+

+
+## Key Design Decisions
+
+1. **Capacity System**: Equipment has capacity that limits total enchantment power. This creates meaningful choices about which effects to apply.
+
+2. **Effect Categories**: Each equipment type only accepts certain effect categories, creating specialization:
+   - Staves: All spell types + mana + combat + elemental
+   - Shields: Defense + utility only
+   - Accessories: Small bonuses, no spells
+
+3. **Stacking Effects**: Many effects can be stacked multiple times for increased power, with increasing capacity costs.
+
+4. **Rarity from Power**: Rarity is automatically calculated from total capacity used, making powerful enchantments visually distinctive.
+
+5. **Time-Gated Application**: Enchantment application takes real time with continuous mana drain, preventing instant power spikes.
