Storm Release: Black Hunting

Seemingly using the envanrablity of the user's Storm Release: Laser Circus technique, but employing the use of black lightning instead of normal lightning,  sends out several panthers which are guided towards the opponent, slashing them as they pass. The opponent takes 6d6 damage from slashing upon reflexing. The panthers then merge into a single, giant panther behind the opponent, which bites them and then explodes. (The bite and explosion take 10d10 damage )====
