Divine Grace
Hey, who doesn’t like to quote Holy Grail whenever an excuse presents?
As the archetypal “shining knight” class, paladins have it pretty good. They’re immune to a lot of things: fear, disease, curses, but also likely also likely dandruff, body odour, and grime. It’s a little known fact a paladin’s touch doesn’t just heal wounds but has amazing grease cutting action.
I wouldn’t be surprised if paladins did not sweat, pass gas, and had excrement that smells like lilacs.
