A 30ft wide/high, hundreds of feet long dark corridor of echoing screams lays in front of you. Massive 30ft squares of intricately carved stone on the ceiling crush down each round. Get to the end to survive and claim your reward.

This is "one" mega-encounter, no opportunities for rest. The crushing ceiling does 20d10 damage if you are under it when it falls.

Priority goes to anybody who hasn't already done this dungeon.
