Crypt Things are strange undead creatures that are usually busy guarding tombs, graves and even corpses. There are two different types of Crypt Things, ancestral and summoned. Ancestral are the more "natural" kinds, while Summoned Crypt Things are called into existence by a wizard or priest.
Crypt Things look like nothing more than an animated skeleton and is always clothed in a long flowing black or brown robe. Their eyes glow with a bright red flash and they have an almost hypnotic intensity about them.
Crypt Things exist only to guard and protect the remains of those who have been laid to rest within their lair. Should a grave robber or any intruder enter the lair or defile or profane the resting place, the Crypt Things become instantly animated. Their greatest ability is the magic of teleportation, a spell they can cast instantly, causing the victim to be teleported out and away from the tomb.
Depending on what type of Crypt Thing you are dealing with, the victims may dematerialize atop a mountain and then fall to their death, or they will materialize miles away from the tomb falling with a crash where ever they land. Another defense of the Crypt Thing is to transport itself right in front of you and claw at you with it's razor like bony fingers. They are undead and few spells will work to kill them. Summoned Crypt Things cannot be killed by anyone or anything other than that who has summoned them.
