Touch of Tyrranor

One humanoid of your choice that you can see within range must succeed on a Wisdom saving throw or become charmed by you for the duration.

While the target is charmed in this way, the sigil of Tyrranor appears on the back of their neck, with a faint purple glow.

The charmed target will act as you direct it, including moving, casting a spell on, or attacking any target other than itself. If the target would otherwise be friendly to the charmed creature, the charmed creature is entitled to a new Wisdom saving throw. 

If the Orb of Tyrranor is touched to the sigil on the target's neck during the duration, the target becomes permanently enthralled by Tyrranor and the caster of the spell loses control of the target.
