rings vs door

We reached the door behind the ticketing counter, which was closed. I jiggled the handle, but it was apparently locked. I didn't have time for this crap. I lifted my right hand and focused on one of the energy rings I wore. There was one of them on each finger, a band made of three rings woven into a braid. The rings stored energy, saving back a little every time I moved my arm, and allowing me to unleash that stored energy all in one spot.
I brought my will to bear on the door as I lifted my hand in a closed fist, focusing the energy of the rings into as small an area as I could. I hadn't designed them for this kind of work. They'd been made to shove things roughly away from me before they could rip my face off. But I didn't have a lot of time to waste putting together something neater.
So I aimed as best I could, triggered the ring, and watched it rip the doorknob, the lock, and the plate they were all mounted in right out of the door, to send them tumbling into the room beyond. Unimpeded by any of those pesky metal security fittings, the door swung inward.
