I am only level 7 or 8 can't remember which, and done everything but the Historian stuff and defeating of the Magister in charge. Basically, I have no idea how I am meant to level enough to stand a chance against this fight. I killed everything except one shrieker and the fight for the boat.
So I assume I must be missing something obvious... is Historian quest essential?
you can beat the final fight even at level 5
hint: barrels are you friends
