Yes. In fact, his staff has runes on it, I think I used that, didn't I? Well, yeah, his staff has runes in it, and he can activate them in different ways. Say there's a fire rune on a sword. He can use the rune to throw a fire ball or imbue the sword with fire. All depends on what he needs. In his staff, the runes are carved, so their permanent, but if they were on there with, say, ink or something, they would dissapear after a few uses.
