Hello,
I'm locked in the second level of the Crypt of Drath.
I found the (http://homepages.uni-regensburg.de/~mim09509/Avernum/AvernumEscPit/Towns/Drath.html) that :
"In the NW corner of the Hall of Tombs is a ledge which I have never managed to get onto. South of the ledge is a passage leading to a corridor with a golem. Once past it you come into the Smoky Laboratory. In the south is a container which is rather hard to see but contains an Energy elixir. There is a tome in the NE corner which does nothing except slow you and call up a Mung Demon and three Vengeful Shades if you read it. They do however drop an Invulnerability Elixir. To the north are two magical barriers (the western one needs Dispel Barriers L2). Behind each of them is a chamber with a Rampaging Infernal. To the east of the eastern chamber is a lever which you should pull. ".
But the entrance to the smoky laboratory is stilll locked by a steel barrier ...
Do I missed something ... can't remember if I fought the Golem but while i'm the place no Golem appears ...
Any idea ?
