 * On this level, there will be a lot of Poison Fields. You can either run through them and then use Antidote, or you can use Destroy Field to clear a path.
 * Go down another level.
 * Follow this path to the east and north. Be careful of Minotaurs. Go down the hole that is circled on the map. You will face a couple Cyclopes down this hole:


 * Head south down the left most passage. Go up the hole to a small room and up again to another room. Here go to the end of this passage and down the hole to a small room and down again:


 * Head south then west then north then take a right heading towards the level door.


 * Head down the stairs BUT BEWARE!!!! There is at least one dragon, one giant spider, one beholder, and multiple demon skeletons.  After clearing this room head to the southeast and through the locked door.
