Black Worm

This enormous worm is covered in onyx plates. Its giant, tooth-filled mouth could swallow an ancient gold dragon as easily as it could desecrate it in dark, negative energy.

Frequently called the Worm of Death, this creature is large enough to devour whole villages or small armies in a single bite. Those that survive a black worm’s bite must endure its poisonous stingers. The poison is so deadly that any afflicted creature that does not receive immediate treatment dies as its muscles turn to jelly within its body. Were that not sufficient to decimate most living things, the worm’s breath emits a spray of negative energy. Creatures foolish enough to attack a black worm find this creature to have an incredibly thick hide and spell resistance high enough to make attacking it difficult, if not impossible.

A black worm prefers to attack by tunneling through the ground and devouring its prey from below, usually in a single swallow.
