Forget me if I get the details wrong, It has been more than a year and I am going off memory right now.
Priest could speak to the dead and revive a fellow BD, giving that BD conv immunity.
On the same time the priest himself was DI once, and had conv immunity.
What would you think about returning the Priest to the game, without the death immunity, and the convert immunity for him and his convert? I think in Throne of Lies, because of the higher power level than TOS, reviving a player isn’t a really bad thing.
He could also get some active ability (which I didn’t think of a fitting one yet) to make the role more active.
