At first level, a gravewalker can take control of an undead creature within her aura of desecration by forcing her will upon it (Will negates, using her hex DC). If it fails the save, the creature falls under her control as if she had used command undead (once control is established, the undead remain controlled even if outside the witch's aura). Intelligent undead receive a new saving throw each day to resist her command. The witch can control up to 1 HD of undead creatures per caster level. If an undead creature is under the control of another creature, the witch must make an opposed Charisma check whenever her orders conflict with that creature's. This replaces the witch's hex gained at 4th level.
