Payback Surge

Payback Surge is a Reprisal Command in Kingdom Hearts Birth by Sleep, exclusive to Aqua.

Mechanics
In Kingdom Hearts Birth by Sleep, Payback Surge allows Aqua to counterattack by lunging forward cloaked in her barrier after being knocked back into the air by an enemy's attack. It has a maximum level of 4. Be warned though; for a brief moment after you use Payback Surge, you're open to enemy attacks.
