Battlefield Defiler (Magus Archetype)

From publisher blurb: The necromantic arts have long been the domain of Wizards and Clerics of dark gods, who find that it is easier and often more effective to make use of a corpse for combat or menial tasks than to coerce the living into doing one’s bidding. The more battle-focused Magus may also find a use for undead creatures under his control, and recently a small group of necromancy-focused Magi has been reportedly experimenting on corpses of all shapes and sizes. These Magi are experts at making use of the corpses of their slain enemies mid-battle.
