The one where you have to drink and then fight the Nords.. the drink doesn't last long enough for you to beat them. When it runs it they just stop attacking and become friendly again so you can't attack either. Anyone else stuck on it?
Answer I found... kite them, but not too much (or they will use their ranged attack). Just hit them, back up, block their power attack (they use it a lot), then pound them. Rinse, wash, repeat... might take a few tries.
Also, use a health potion very early, as soon as it will help. They don't have to kill you, just get you down to like 20% (rough estimate).
I'm also having trouble with the log roller going form hostile to neutral after some other human player jumps in and gets a couple blows in. It's like they are switching targets, so i can never finish.
