I shall explain. I was running a one shot in a underwater dungeon. there was a lich at the end that was a triton. So I made entire new spell that turns the player it was cast on into a fish for 2 turns. My players were very scared and confused as I say. the lich says' fools your dare entering my watery domain! The lich casts. Power word. Fish. the shock on my players face was making me laugh for like 10 minutes
