Bone monsters are undead creatures assembled from the bones of fallen creatures and knitted together with necromantic magic. They are mindless automatons that obey the orders of their evil masters. If destroyed, they collapse into piles of unconnected bones.
These undead creatures appear as portcullises or gridwork-curtains created from interlaced human and beast bones adorned with sharp bone spurs.
A bone lurker can be created by means of an animate dead spell, and it requires three corpses to create one bone lurker.
