Aura of Undeath

When you first cast this spell and while concentrating, any humanoid corpse within range of the spell is reanimated as a zombie or skeleton. Certain corpses can be transformed into an appropriate type of undead(DM's discretion). You can use your bonus action to command any or all of the undead created with this spell. They can follow basic commands, but can not perform complex tasks. If you maintain concentration for the full duration of the spell, all of the undead created by the spell are permanently under your control.
