Death By Stone Juggernaut.

Memorable Heroic Endings Part 4.

The last thing you expect to encounter under a Mayan temple is a stone juggernaut. But this is what happened to a few characters in WOTC's Tomb Of Annihilation. One even succumbed to a good flattening. I can remember running back down a pathway losing so much hard-fought ground to an unstoppable block of stone on wheels. Subsequent replays of the game have been hampered by the thought of having to reach a certain point in the game before it appears. you can't miss the encounter if you want the ability to make the final chambers. I sympathize with Indiana Jones on just how stressful a large stone trap can be. below is a reconstruction of the event with some clown as the real adventurers flat out refused to appear.
