I'm playing on the console and I've gotten as far as fighting Alduin, as I try to fight him my Dragonbane sword won't activate it's power. Am I missing something? Please help. :P

hit dragon

Ok...., but apparently in using the berserk power the enchantment of the sword doesn't work. :/ (Figured this out later)

that's not true though, it does still deal extra damage

hmm... :/ It doesn't work for me. I'm going to have to go rambo and hope I dont die... (I tried this and I get it 1/2 of the time now.) May be a glitch for just my disc.
