I'm at level 33 or so...these are very tough to tackle. I think you've got the difficulty a bit out of range?
These are certainly
not low to mid level dungeons. You'll need most of your major skills near to maximum before you should even attempt any of them.
As Pink Dragon says, they're meant to be tough.
These are one of the few places in the game where a very high level character can, and quite often will die.
Don't download these if you want just a jog-through dungeon with good loot. Even if you clear a dungeon, some of the better items will not show up on the first run, so rinse and repeat is called for.
Now if you want to know if your avatar is godly.............. :facepalm: :banghead: :nono:
This is how I found out how hard they can be
