Creepy Crawler

The Creepy Crawler embodies everything unsettling about necromantic craft. It scuttles low to the ground on four limbs, its horned skull thrust forward, its maw bristling with jagged teeth. The way it moves, sudden, raking bursts of speed followed by unnerving stillness, unsettles even hardened adventurers. Unusually for undead, they are impulsive, prone to break free of control, and roam the world untethered, perhaps as a consequence of their generally unstable nature.
