# US-005: Use Assassin abilities

As the **Assassin**, I want stealth and burst mobility so that I can ambush opponents while accepting a combat penalty afterward.

## Acceptance criteria

- [ ] The Assassin can activate ten minutes of invisibility once per rolling hour using the named Assassin ability item.
- [ ] Invisibility displays no potion particles.
- [ ] Activation while in the same world and within the configured Tyrant range grants twenty minutes instead.
- [ ] Proximity is evaluated when the ability is activated and does not alter the active duration afterward.
- [ ] The Assassin can double-jump once every 60 seconds without requiring an item.
- [ ] A successful double-jump grants Speed for 15 seconds and Weakness III for 20 seconds.
- [ ] Grounding and supported movement reset jump availability only after the 60-second cooldown has elapsed.
- [ ] Ability cooldowns use unpaused elapsed time and survive death, logout, and restart.
- [ ] The player can inspect remaining cooldowns and receives clear feedback when an activation is unavailable.
