As suggested here (//%22http://www.efupw.com/forums/showthread.php?103692-Make-the-Ogre-Quest-Light-Settings-Darker!%22), I guess the Troll quest could use a darker lightning as well.
OH! It's also a shame that I didn't see any troll hag when I got there. Must add one, yes? :D
But you were there were you not? If we have too many hags the quest would be unbalanced!
Maybe could use a couple more rock throwing trolls? Seems like it was only at one point where we were getting hit by rocks from one troll.
