Effect Duration Boost
Buff ID N/A
Passive ID 11009

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 makes her immune to any Turn Skip effects that last for less than 3 turns.

Buff Application

If a unit's buff were to have its effect duration reduced to 0 turns, the effect will not apply at all. This also means a buff with an effect duration of 0 turns cannot overwrite pre-existing buffs.

For example, if Damage Mitigation effects have their effect duration reduced by 2 turns, Reborn Íkaros Azius' 3-turn mitigation effect on SBB will only last for 1 turn. If Divine Savior Mikael's 2-turn mitigation effect on SBB were to activate, Mikael's mitigation effect will not overwrite Azius' mitigation effect.

A Feast of Tears

BFWiki AFeastOfTearsEffects

Certain quests have invisible enemies usually named A Feast of Tears. These are not meant to be targeted, as they cannot be targeted without scrolling through each enemy that appears in battle while checking enemy buffs. Additionally, they have Damage Immunity and Stealth effects active throughout the entire fight. When present in battle, they reduce the buff turn duration of the following effects:
