The Dolmen Tomb – Area 9: Slaves' Crypt

Dozens of ancient skeletons are laid out on straw mats lining the dusty floor.

• Skeletons. When the secret door opens (whether by pushing it open or by triggering the eastern pressure plate in area 1), 3d3 brittle skeletons rise immediately and attack, entering area 1 if necessary. Each round thereafter, 1d3 more skeletons rise and join them until all have animated (30 total).

–Loosely-Assembled. Because they are a collection of barely-held together bones, a brittle skeleton can pass through a Small opening or an ally’s space without penalty. Two brittle skeletons can occupy and fight in the same space without being considered prone.

Actions 

–Bony Claw. Melee Weapon Attack: +2, Reach 5 ft., one target, Hit: 4 (1d4+2) slashing.

–Push-through. When faced with a line of enemies, a brittle skeleton can use its Action to throw itself against an opponent’s space, breaking apart into its constituent bones and then reforming on the other side. The brittle skeleton can only move up to 10 ft. in this manner, but can do so through spaces controlled by another creature.
