I have this invincibility now as well, going up to that village the trolls are attacking I can not even get one hitpoint of damage. Not even if I lure 20 or 30 guys around me.
Their level 21 I believe and I'm 31.
Kind of sucks that they can't even do any damage even when they are surrounding you.
I'm also only getting 31 XP gained and 1XP from magic on every kill. Even the giant troll in the cave with the two rune stones or whatever that you need. That XP and he deals no damage at all.
I personally think something got messed up somewhere when I leveled to 31 or when I found some Unique items as my dragon still takes damage from those level 21 flaming rock throwers that are down in that one area in the fjords.
My human form takes no damage at all.
No fun in that.
