Transmutation

Meanwhile, a transformation was happening in the fist that gripped the rock; the skin of his arm and hand appeared to be growing polished and hard, turning almost exactly the same gray as the stone. As one of the trolls tried to stomp the nimble elf into the bedrock below the hill, he leaped suddenly forward. He didn't strike the creature with that brass blade affixed to his arm, though; he only touched the creature on the leg with his new stone hand.

Suddenly, the same transformation that had covered the young elf's arm began to spread rapidly across the troll's leg. It's green-gray hide, already pitted and craggy, changed to rough stone. The rock moved in a ripple up its torso, creeping ahead with alarming speed. The lumbering creature had enough time to drop its tusked jaw open in surprise before the wave of stone swept up its face, the expression of surprise freezing in place.
