• 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.
