MASS EFFECT: OPERATION RESURGENCE
BIOTICS - NOVA
Nova is a close-range shock wave power which utilizes the Vanguard’s high-risk, high-reward combat system. While expending the remainder of your biotic barrier, Nova inflicts a high amount of damage to surrounding enemies, and even pushing them back and sending them soaring into the air. There is no cooldown—it can be used whenever the Vanguard has barrier remaining.
