Unbind

This spell releases a undead who is bound to servitude to a master, and gives them free will. Choose an undead to touch the soul pearl to for the casting time of the spell. The target undead must be bound to a master and/or lacking free will. The target undead gains free will and no longer must follow any orders from their master.

The unbound undead is charmed by you for 30 days or until you or your companions do anything harmful to it. When the charmed condition ends, the unbound undead chooses whether to remain friendly to you, based on how you treated it while it was charmed.

In addition, if the undead’s existence was previously non-permanent, it becomes permanent when they are unbound, allowing them to live until destroyed.
