I've never been one for the slow, shambley type.
The Necromancer stands over a corpse and makes a series of grandiose lifting gestures. The corpse rises from the ground as though suspended by invisible strings, barks a pained groan, and lands on its feet, now a full-fledged member of the living dead.
The monster hungers for brains and will aggressively pursue and attack anyone it sees, including the Necromancer that created it.
Target a corpse that has died within the last month, spend an Action and Exert your Mind to raise the dead. The resulting creature is a husk of their former selves, a mindless, brain-hungry zombie. It has no memory of its past life, and no hint of its personality remains.
The creature lasts for one hour or until re-killed. It is revived at full health. Any Injuries it had in life are not accounted for when determining its penalties or progression towards re-death, though they may affect its ability to perform certain actions at GM's discretion.
The revived creature's Abilities are all set to 0, and its Charisma, Wits, and Intelligence, are all set to 1. Its Brawn, Dexterity, and Perception are the same as it had in life. A revived creature cannot use any Powers.
