Green stumbled as the world shook. The violent discharge of mana from the crystal didn't seem to originate from the broken shards on the ground, no it was somewhere else and it was shaking everything. Dust and loose stone fell from the ceiling as Green fought for a moment to keep her footing. The shaking didn't last long and once it was over Green threw her mana into the wind letting her move with her max speed, not caring for the inefficiency of the expenditure to position her behind Gloves and slam the palm of her hand into his neck. Dropping him instantly. It was somewhat risky, and had a chance to be a fatal attack, but Green wasn't terribly concerned at this point in time.
Caution by 'The Killers' fits very well
