# US-009: Purchase and use Tyrant abilities

As the **Tyrant**, I want permanent upgrades and limited roster intelligence so that I can shape my reign and assess the resistance.

## Acceptance criteria

- [ ] Purchasing permanent Strength applies the configured Strength level throughout the current reign while the game is running.
- [ ] Purchasing permanent Resistance applies the configured Resistance level throughout the current reign while the game is running.
- [ ] Permanent effects are restored after death, milk consumption, ordinary effect removal, login, restart, and replacement by a shorter or weaker effect.
- [ ] Roster intelligence can be activated once per rolling 24 unpaused hours after it is purchased.
- [ ] Roster intelligence reports the number of active Vigilante-side members without revealing their identities or locations.
- [ ] Intelligence counts the current Vigilante and living assigned Followers, whether online or offline, according to configurable counting rules.
- [ ] The Tyrant can inspect ability ownership and the remaining intelligence cooldown.
- [ ] Purchases and cooldowns survive restart and end with the Tyrant's reign.
