Dungeon Mastery: The Turtleback Tomb

The Turtleback tomb moves slowly across the desert...

1. The doorway of the tomb is closed with a massive stone, serving as a door.

2. The tomb's floor space is 150 square feet. Inside the tomb, urns with the bones of deceased ancestors stand on multiple rows of stone shelves, in the order of seniority.

Thirteen skeletons rise one after the next from their urns hell bent on slicing up the tomb robbers. They are immune to turn undead, and have the stats of bone golems.
