# Buff & Debuff

**Buff** and **Debuff** refer to effects that provide temporary enhancements or reductions to a character's attributes, abilities, or performance in battle. These effects can last for a specified number of rounds or be permanent until removed.

**Duration**: The duration of a buff or debuff is measured in rounds. Each time a character takes their turn, the game checks the remaining duration of any active buffs or debuffs.

* For example, if Character A has a debuff that lasts for one turn remaining, once it is Character A's turn again, the debuff will end.
