blocks Vitto's gun

"Drop back!" I snapped, as Vitto came streaking toward me down the other sideline. He was reloading the gun as he came, dropping the old magazine, slapping a new one in. I lifted my shield bracelet, readying it - then hesitated for a fraction of a second to get the timing just right, gauging angles of incidence and refraction.
Vitto's hand game up and the gun snarled again.
I brought the shield up at the last second, a flat plane perpendicular to the floor, and Ramirez took a hopping step back just in time to get behind the shield as it formed. Twenty or thirty bullets ricocheted off the invisible barrier in a shower of sparks - and spalled more or less toward Madrigal Raith and his magical protection.
