This is a weird thing I've noticed ever since I started going to the 80+ hive, and it's kept up as well at the withered dungeon, and now in the eater place. I seem to go in a dungeon, and get my butt kicked but good for a while. Then, something happens. I quit taking as much damage, and it almost gets boring, insofar as I have no really health worry come up.
Wouldn't it be funny if the game allowed you to "learn" to stay alive once you were in a dungeon longer?
