I have a small group of adventures. One of them is playing Matt Mercer's "Blood Hunter" class also described on Geek & Sundry. A large part of the story for him is hunting undead creatures. One of the undead I want to use is ghost, but the party has no cleric or paladin.
Is there a way to remove possession other than some of the ones here: Are There Any Mechanics for Removing Possession?
I thought about Turn Undead, but again, they have no cleric or paladin. Is there another way to remove it that I am missing?
