# Status Effects

Status Effects apply reusable, time-aware gameplay behavior to a Roo Stats Component. They support immediate effects, periodic effects, duration, stacking, refresh rules, source tracking, granted tags, and UI display queries.

## Pages

* [Creating a Status Effect](/roogame/roo-gameplay-framework/status-effects/creating-a-status-effect.md): configure duration, actions, tags, and application rules.
* [Stacking, Duration and UI](/roogame/roo-gameplay-framework/status-effects/stacking-duration-and-ui.md): choose stack policies and display Buff progress correctly.

## Common Uses

* Damage over time and healing over time
* Temporary stat bonuses or penalties
* Permanent passive effects
* Stackable item or skill effects
* Buff and debuff icons with remaining-time progress

Status effect definitions are reusable Data Assets. Each Stats Component owns its own active runtime effect state.
