The bottom levels of the dungeon are infested by more max-damage monsters which look more intimidating than they actually are. Well, except the Invisible seeker, which doesn't look like anything at all. It will still appear on the game's report of "things you see" though, so start firing if you "see" one. The only special attack here is the Mind whipper's mental attack, which drains Intelligence. This isn't that big a deal, and it's easy to recover from, but it's still quite annoying. There's no real need to go to level 10 if you're looking to kill a Balron for your final gem Quest, but if you do, be aware that there is no ladder down, and the Ladder Down Spell will not function.
