A home for things that you thought would be great, but turned out not to be such a good idea after all.
It was a bad idea to....
Use a wild magic character as stealth character.
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.
