BC Fill when attacked

BB when attacked (commonly referred to as “BB on Hit” or “BBoH”) is an effect that boosts BB gauges of units that receive any form of damage. This effect occurs once per enemy attack.

If units are hit by a Random Target attack, each random hit will boost BB gauges.

If an effect has a chance of boosting BB gauges when attacked, each attack calculates probability independently. For example, if a unit is hit with three different enemy attacks (not hit counts) and has a BB-on-hit effect that activates at a 50% chance, the said unit will have a total 87.5% chance of activating BB-on-hit at least once.
