HC Efficacy

HC Efficacy (also known as HC Effectiveness) is an effect that amplifies how much a unit’s HP is restored upon collecting HC. Due to this nature, HC Efficacy does not amplify other HP effects, such as Heal when attacked, Heal on Spark, etc.

Its opposite counterpart is HC Efficacy Reduction.

Formula
Amount Healed = Total REC * (100% + HC Effectiveness Multiplier) / RandomBetween(3.0, 4.2)

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

For example, Lord-type max-leveled Kaiser Glowy equipped with White Bangle (25% boost to HC Efficacy) will result in the following:
 * Assuming no imps were fused, Kaiser Glowy’s Rec stat is 907.
 * Without White Bangle, Kaiser Glowy will heal anywhere between 2721~3809 HP.
 * With White Bangle, Kaiser Glowy will heal anywhere between 1133~4761 HP.
