Reformatted Explosion

A pressure plate.

Batman was three long steps from the vault door. He had covered two of them when the bomb hidden in the wall of safe-deposit boxes went off.

He lost some time, but not much.

When he came to his senses, he lay crumpled against the base of the stone staircase, singed and smoking. The shrapnel from the metal boxes had shredded part of his cape and nicked him through his suit in several places. The fire raging in the vault was sucking air down the stairs. It had already spread into the reception area. Batman’s ears rang, and the impact of the blast wave had left him feeling like there was something in his lungs he couldn’t quite cough up.

The Riddler’s adapting his style, he mused. It may be time to pull out the armored suit.

The interior of the vault looked like the inside of a blast furnace. Fire burned so intensely there that it was swirling out through the door—and up, as if the explosion had knocked down an exterior wall and exposed the vault to open air. There was no way any of the Riddler’s thugs had survived.

Creaking sounds from the ceiling over the reception desk got him moving again. He went up the stairs, limping at a sharp pain in his right heel. Other than that he seemed intact, for the most part, though as he reached the main floor, he noticed his nose was bleeding.
