I once created a character around rhyming. It was right when they announced centaurs; I decided that the only logical course of action was to make one who only talked in rhyme, so every time he said something, he would immediately follow it with another sentance that rhymed with the first. He was called Hentaur the Centaur. The DM banned me from the game.

You fool! You’ve forgotten the best one: creating characters based on eye-rollingly bad puns!

Wasted me: like, what if Michael Jackson was a sorcerer that believes he’s a druid?

Not wasted me: my God I’m a genius
