BC Efficacy Reduction

BC Efficacy Reduction (also known as BB Gauge Fill Rate Reduction or Ares down) is an effect that reduces how much the BB gauge is filled upon collecting BC. It is the counterpart to BC Efficacy.
Unlike its counterpart, BC Efficacy Reduction does affect other BB gauge effects, such as BC Fill when attacked, BC Fill on Spark, Burst BB Gauge Fill, etc.
