I made a bard/wild magic sorcerer. It looked like a fun CHA-based combination.
But the wild magic is wont to crash the bard's stealth, subetefuge or social interaction operations.
Like casting "invisibilty" to penetrate a building unseen, but wild magic kicking off a fog cloud which makes all the guards in the street attack your party.
Me inner Ork sayz dat dis da FUN part :P
