BB Atk Reduction

BB Atk Reduction effects are subtractive boosts to the BB Atk modifier units have on their skills, effectively decreasing damage output. Currently, this debuff is only available on enemy skills.

For more information on how BB Atk is factored into the damage calculation formula, see Damage.

Interactions with the Attack stat
BB Atk modifiers, including buffs and passives, are factored into the Atk stat and thus, they are affected by Atk parameter limits.

Interactions with HP-scaling attacks
BB Atk boosts always apply last and cannot affect the HP-scaling modifier by any means.
