Shadowsetzer: Welcome to Durlag's Tower, friend. I didn't even bother going to the area on my last playthrough. I find it far too annoying for the rewards it offers, especially since I go to finish the game right afterwards anyway. (What's the point in getting weapons if they're barely gonna be used?)
Bluerussian: Played it for completeness I suppose. I was more interested in leveling up as far as possible, and to that end it helped. You do get to fight a greater demon if you finish the dungeon which is completely insane at level 7... I had to do some serious experimenting to figure out how to kill it without getting murdalated by the thing. Otilukes Sphere is all I'll say...
Can't wait to play the other BG engine games.
....Please don't remind me of him....
(Goes and curls up into a corner until he remembers he's currently playing as a half-orc berserker)
But yeah, I've played through the Tower and Aec-letec (sp?) at least once or twice.
