So how common are these "player vs rocks dropping on head" quest? Armormaster

It can only be done with armor, that's the catch. In the first quest, I was playing a witch with all EV/ES equipment. It took me 6 tries to finish the level (my first, and only, death(s) for normal). I was wondering if it was meant to be so seriously difficult so early on, as if were you supposed to come back to it later.

Glad I didn't try this on HC.

On the other hand, if you stop to kill the monsters, you get some phat loot. The item rarity % must be way up for the area.
