Single Minded. When summoned by Vorkath, the Zombified Spawn is assigned a creature to move towards. The Spawn will try everything in its power to get within 5 ft of the chosen creature, taking the most direct route available. It will run straight through hazardous terrain without any regard for its own safety, but will go around obstacles that are blocking the path if need be.

Turn Vulnerability. The Zombified Spawn has disadvantage on saving throws against any effect that turns undead.

Self-destruct. The Zombified Spawn bursts onto a creature within 5 ft of it. The creature must make on a DC ?? Constitution saving throw, taking ?? (??d??) cold damage on a failed save, or half as much on a successful one. This kills the Spawn, leaving no remains.

Burst of speed (1/day). The Zombified Spawn takes the Dash Action as a bonus action.
