Lowkey considering a concept of a Lawful Good paladin of Asmodeus. Technically doable with the Pact Servant trait.
The Devil's Advocate. In reverse. A Public Defender arguing against the church's position in any given case. A contract is only as good as its weakest clause and they seek to ensure all contracts are rock solid. He's the one the poor all visit to make sure the contract they're about to sign doesn't have any surprises.
And when a devil (or daemon) tries to weasel out of its side of a bargain, he's the one the Church calls on to smite them back into line.
Asmodeus brings order like no other can, his goal is to temper that order so it benefits the greatest number possible.
