[Ah, if Hayame has spoken to Fane about Sebastian, then no wonder the man has such a strong disdain for him. Plenty of people can’t muster any dislike for Sebastian at all, even though his true nature is no real secret.]

He is extremely fast and strong, for one thing. He can also transform—obviously into human shape, but also into animals, and into shadows as well. And he can give himself claws, of course. Personally, I would take pains to avoid a direct confrontation.

But as far as I know, he is also quite inexperienced when it comes to magic. At least, that was the case some months ago. He had no senses to detect it, and no experience with it from his own world.
