ATK Debuff

An ATK Debuff, also known as Tarunda, decreases the target team's attack by 20%.

Mechanics

In a nutshell, damage is first calculated using the attacker's PATK or MATK stat, minus half of the enemy's PDEF or MDEF stat. This is then multiplied by the sum of ATK buffs, ATK debuffs, DEF buffs, and DEF debuffs. After that, the skill power, damage boosts, damage reductions, resistances, etc are applied to calculate the final damage. For more information, see the Damage Formula.

Debuffs cannot stack - the number shown in-game is the buff's remaining turn duration.

• If a buff is cast while it's already active, the new buff will replace the old one only if it would make the duration longer.

Buffs and Debuffs are opposites, so they will cancel each other out regardless of turn duration.

• For example: If a team has an ATK Debuff, and then an ATK Buff is applied, then both effects will disappear and the team will be in a neutral state.

Duration Ticks

The turn duration for Buffs and Debuffs will tick down at the start of a turn belonging to the team that originally cast it.

• For example, if your team set up an ATK Debuff on the enemy, then the Debuff's duration will tick down at the start of your next turn.
