Used the Dup trick to dupe up a dozen minor Restore potions ( it was the only potion I had left!!!) and finally got out. I was lvl 18, using a 3rd lvl Meteorstrike and having a VERY hard time.
Did some side quests and exploring. Got to lvl 19, raised Meteorstrike to 4th level, went back in, and it made all the difference in the world!!!! Kill 'em in half the time compared to 3rd lvl Meteor! Game has some balance issues; it would be OK to have a too tough dungeon, but NOT when you get trapped in it like this one.
btw the Guardians could be hit good by my low level mace (bat of Striking?), sometimes did more damage than 3rd MeteorStrike
thnx all
