That part of the game could have been done a little better. I take 0 damage at level 30+ from anyone outside a General in the fortresses and they only do like 100 hitpoints damage in a minute of me just standing there doing nothing.
I just stand there in just my bra and panties and laugh till I get bored, then go over and bare fist punch them into mulch.

Thought stripping down would make me way weaker but taking off my armor hardly makes any difference at all in my stats, like one or 2 points lower.
Heck had a 3 man group of black ring, level 28 I think and went and ate supper last night and they were still plugging away at me with no damage 45 minutes later.
Well at least my dragon still gets slaughtered, just did Raze's fortress and died like 8 times from those dragons and blimp guys. I got the last laugh and cleaned them all out eventually with a lot of quick saves.
