Burst BB Gauge Fill

Burst BB Gauge Fill (commonly referred to as Instant BC Fill) is an effect that boosts the BB Gauge upon using a skill containing the said effect.
Because BC fill boosts gauges based on BC values, BC fill becomes more effective with BB Gauge Cost Reduction.
This effect is not affected by BC efficacy boosts but is affected by BC Efficacy Reduction, causing the effect to boost BB gauges by a lesser amount.
