You exert control over an undead creature. Choose one undead you can see within range. The target must succeed on a Wisdom saving throw or be charmed by you for the duration. While charmed, you have a telepathic link with the creature and can command it (no action required).   The creature may repeat the saving throw at the end of each of its turns, ending the effect on a success. Creatures with CR higher than your priest level cannot be targeted.
