One of the cool aspects of fiends that I don't see get a lot of play is the possessing of mortals.
Where do the rules on this appear in Pathfinder? I'd like to read-up on it so I can make use of it.
There was a thread on this a few years ago, most fiends just treat possession as the Magic Jar spell, like the shadow demon. There were rules in one of the Council of Thieves modules, The Infernal Syndrome, for possession but those rules made possession of mortals costly, difficult and very short-lived.
Adventure Path #28 from Council of Thieves - The Infernal Syndrome had rules for infernal possession.
I think there may be some elsewhere, but that is my go-to.
Thanks. I'll have to take a look at AP#28 again.
I know shadow demons have it in their write-up because it's their "thing," but wasn't sure if the rules for other fiends doing it were different.
