The Gold Top of Evil
Playing an evil character, as the entire party is, can really show just how devious one can get. When I, Steve the Pirate, find myself in an obvious prayer room to a good deity, inside the temple of a paladin we are trying to corrupt, I seize the opportunity to be as evil as possible.
I grab a quill and some ink from my backpack and deface a painting, depicting the god, hanging on the wall with a moustache, some NHS-rimmed glasses, and black out a few of his teeth. How much more evil can you get?
