#Dungeon23 Tomb of the Vampire Queen, Level 7, Room 21

 Going back to Room #18 and taking the door behind Gzor'nak this leads to a long hallway covered in gravel. When the party reaches a large chamber (Room 21) the gravel begins to move and form itself into a giant monster.

The monster has the stats of a Stone Giant. It regenerates 2 hp per round. 

If it is reduced to 0 hp it will fall apart but reform when it reaches 10 hp.  

This can be prevented by mixing the gravel with volcanic ash (everywhere prior to room 10) and water.  OR by use of a Dispel Magic.

The corridor continues on.
