Get the xEdit/zEdit script that tells you what the encounter zone levels are in the name of the dungeon, and you'll be fine. The hard thing with MLU is that you can't tell what the level of the dungeon is until you're halfway through and getting stomped. So being able to see what you're getting into before you get into it is very useful. I can't remember what the name is, but I do know there are several of them on the nexus.
