Effect Duration Boost

Effect Duration Boost is an effect that can either extend the turn duration of certain buffs or reduce the turn duration of specific debuffs.

For example, Nia, Maverick of Elysia’s Extra Skill effect reduces the duration of the Turn Skip debuff by 3 turns. This will make her immune to any Turn Skip effects that last for less than 3 turns.
