By scheduling the eruption event without cancelling the previously registered eruption events, Heigan's eruption (or dance) would overlap and cause a runaway scenario, where eruptions would not follow a proper timer.
By using Reschedule and not locking the Eruption event to the fighting phase, the dance now works as intended.
