So I'm up to the quest 'The Fallen' in the main questline, in which you have to capture Odahviing, and I go to attack him with everything I have. Spells, swords, shouts, and he doesn't take any damage. At first I thought he was just so powerful, but I looked up a walkthrough and the guy defeated him and he was a level 17, and I'm 27. I assume this is a bug. Anyone experiencing something similar and if so know how to fix it? I have started a new character though, so I might try to get to that point in the main story again, but I'd rather just get it done on my first one. Thanks in advance.
