...He can't read your mind. I don't know about lying. He can find a person as long as they or the building isn't warded - and teleport there instantly. He has quite a bit of magic, so assume he knows several spells. He can perform illusions. One of those makes it seem as though time has slowed. He can burn his symbol into someone's bone, and it lets him know if they're in danger. Possibly other things about them too, I'm not sure. I've got to assume he can heal himself as well.
