How to cause as much chaos as possible

I have been invited by a friend to a level 20 battle royale style one-shot where the winner's character becomes a god in a separate campaign he is running, I have a goal, not to win but to cause as much chaos as I possibly can, I obviously picked wild magic sorcerer. I am asking for advice on how to cause as much chaos as possible, rules as follows: were allowed 3 magic items of ANY rarity, no multiclassing, 1 week of in universe prep time, and no leaving to other planes of existence. Any advice on how to fuel my endeavor to wreak havoc would be GREATLY appreciated.
