Stealth’s attack speed and stamina

Stealth spun through the mob. Her weapons put down seven exes and three Seventeens. A spinning kick crushed another skull, the batons crossed to force down a rifle, and a head butt left a gangster reeling.
She lunged forward and thrust the batons into either side of an ex’s head, a rough-looking man with a beard, and its skull caved in as the weapons collapsed back to their storage position. Her elbows sent two dead people stumbling back and her hands dipped forward to pull the Glocks out again.
Nine rounds dropped five exes, left two Seventeens screaming and clutching their knees, and gave her a clear shot at Rodney Casares, less than fifteen feet away.
