The Demigod Files
During the fight with Percy Jackson, Thalia, and Nico, he was shown to be able to almost kill them with his spear. And is very fast with it too, seeing as how he stabbed a rock where percy had been standing a half- second ago. He kept thalia busy, fighting her while she had two Hunting Knives.
