Irwin is very intelligent, big, strong, and at fourteen he was already endowed with life force like that of an adult wizard strong as Harry Dresden. When in college, his power has grown so much that Dresden equates his magical force to that of Ebenezar McCoy, one of the strongest members of the Senior Council, when he gathers his will for a big spell. He is therefore capable to engage in a steady ongoing sexual relationship with a Connie, an unawakened White Court vampire, without being harmed by it. Irwin inherited his magical ability from his father. He also inherited a reserved and kindly nature from him.
