When I reach Svadilfari and finish the conversation with him, he immediately kills me with one hit (it's always some blue orb spell, can't avoid it with rolling/jumping/hiding). The same thing happens regardless if I accepted his quest to kill Aurelius or if I decided to just go and slay the evil goblin.

My character has 1156 health and is at level 33 so getting killed in just 1 hit seems unreal, so I'm wondering if that's a bug?
