# US-014: Use class ability items

As a **class holder**, I want a recognizable inventory item for my ability so that activation is fast and understandable during play.

## Acceptance criteria

- [x] Each item-triggered class ability uses a uniquely named standard Minecraft item with hidden persistent ownership and ability metadata.
- [x] Right-clicking or swinging the appropriate item activates the ability without also performing an unsafe vanilla action.
- [x] Another player cannot activate, retain, craft with, place, store, frame, dispense, or otherwise transfer a bound ability item.
- [x] A cooldown ability item disappears only after successful activation and is restored when the cooldown finishes.
- [x] The Tamer's named fishing rod has no cooldown and remains available after successful capture or placement.
- [x] A dropped class ability item vanishes immediately; a dropped captured-mob item instead attempts to spawn its mob safely.
- [x] `/tyrant item` restores currently available missing class items but cannot bypass cooldowns or create duplicates.
- [x] Missing ready items are restored on login and cooldown completion when inventory space is available.
- [x] When delivery fails because the inventory is full, no item is dropped and the player is told both why and how to use `/tyrant item` after making room.
- [x] Bound class items are removed when a player loses the class or the Tyrant's reign ends.
- [x] Death, inventory movement, server restart, repeated commands, and concurrent events cannot duplicate a bound item or its captured mob.
