So what is the supposed level for surviving this dungeon? My team of 4 is lvl5/6 and I cannot get past the 2nd lvl. I only get to the 3rd room about 30% of the time and usually with 2 characters that are damaged and poof get my head handed to me.
If this was a a real game of D&D players would walk out on the DM.
