Key features: - Add/remove items with inventory capacity checks - Equipment slot validation (weapon, off_hand, helmet, chest, gloves, boots, accessory_1, accessory_2) - Level and class requirement validation for equipment - Consumable usage with instant and duration-based effects - Combat-specific consumable method returning effects for combat system - Bulk operations (add_items, get_items_by_type, get_equippable_items) Design decision: Uses full Item object storage (not IDs) to support procedurally generated items with unique identifiers.
