Most of Nuri's ice, magically augmented though it may be, melts harmlessly into water and then fizzles to vapor as soon as it comes too close to the sulfuric flames. At least a few of them, though, find their way through and lodge into the clone's chest and abdomen.

"Ah... wow... That hurts. Did you do that, Yuuuuuuu........go?"

He pulls one of the icicles out and melts it with another burst of flame.
