A debuff is any status effect applied to any character (active or inactive) which has a negative effect upon that character. A debuff is the opposite of a Buff

Debuffs are always coloured red

StackingEdit

Some debuffs are stackable. This means there can be more than one of this debuff active on a character at any given time, providing a greater effect. The same debuff caused by different moves are always stackable.

Non-stackable debuffs will replace an already existing debuff caused by the same move, effectively resetting the duration of the existing debuff.
