Tips for Beating
You'll need to shoot the arrow in his mouth, and once you do that he'll spew out a ball of exploding fire (which will explode when touched), but you'll need get him to touch it, thus causing him to turn into a crystal. Quickly shoot the crystal before he reforms, or you'll need to repeat the process.

NOTE: Shoot him asap, the arrow will stuck in his body so retrieving the arrow means pulling him towards you, that's the only way to bring him in touch with the stone he's spitting. When it turns into crystal quickly recall your arrow and shoot!
