Yeah, it's a very fuck-you battle, but it comes at the end of the DLC. I think a lot of DLC in that time was meant for players who wanted more beyond the main quest, rather than as something that would fit directly with the base game. As you say, harder than Sarevok for sure.
Overall how did you enjoy Durlag's Tower and BG1 in general? Are you looking forward to BG2?
