This large skeletal humanoid's clawlike fingers are at least two feet long. Worse, the slender, knife-sharp claws contract and extend in length from moment to moment, sometimes instantly reaching a length of 10 or more feet, before slowly contracting.

Boneclaws are bloodthirsty undead that enjoy using their extendable claws to bring death to the living. The lore of the dead does not reveal from what dark necromancer's laboratory or fell nether plane boneclaws entered the world. Perhaps they merely "evolved" from lesser forms.

The boneclaw is an intelligent skeletal undead that possesses exceptional control over the length of its claws. At will, a boneclaw can extend one or two of its finger-claws out to a distance of 20 feet, neatly skewering fleshy creatures that stand in the way.

A boneclaw stands about 8 feet tall and weighs about 300 pounds.

Boneclaws speak Common and Abyssal.
