Yeah it is actually one of the great places, (along with Subterra at the Pharos) to level up there even up until late in the game. Have fun going through there when you have to face Fury, Humbabba, and Chaos back-to-back-to-back. I was to lazy to run back out and save again, so I stretched it out and sucked it up, and it was one helluva ride through the death chamber at early levels! :o
