Can you guys give suggestions how to have a cleric switch domains believably? One of my Players wants to switch domains for his cleric from grave to trickery. He wants to be a cleric who worships Mask.
I thought of making all his spells fail until he renounces his gods and then conveniently runs into some travelling missionaries worshiping Mask, but I think this is a little too simple and boring.
I also thought about his cleric getting tricked into worshiping the wrong deity, but that might make his character look like an ass.
I greatly appreciate any creative input.
