BC Efficacy

BC Efficacy (also known as BB Gauge Fill Rate) is an effect that amplifies how much the BB gauge is filled upon collecting BC. Due to this nature, BC Efficacy does not amplify other BB gauge effects, such as BC Fill when attacked, BC Fill on Spark, etc.

Its opposite counterpart is BC Efficacy Reduction.

Mechanics
For every BC obtained, BC Efficacy fills a bigger portion of the BB gauge.

For example, a unit equipped with Fury Core (75% boost to BC Efficacy) collecting 20 BC will fill 35 BC worth of its BB gauge.
