Caiaphas wasn't expecting the bullets to do more than make movement difficult for them, and danced backwards, carefully picking each shot's placement, since his ammo was limited. Once the trolls started charging, however, he used the second of the three charges on his boots, and reappeared next to the troll that had dropped, the sword already swinging downward to decapitate it, its blade bright with flames. Once its head was rolling, and he was sure the wound was burned shut and cauterized, he  moved backwards, keeping some distance between him and them. The last charge on his boots was for emergency evasions, though he knew if he had another fight after this one, he was going to be up the creek without a paddle.
