All or Nothing

All or Nothing is a badge in Paper Mario and Paper Mario: The Thousand-Year Door. In Paper Mario, it can be bought from Rowf and Rhuff's badge shop after Chapter 4 for 100 Coins, and in Paper Mario: The Thousand-Year Door, it is found in the Palace of Shadows, in the room with randomly-protruding spikes, and are rarely dropped by Dark Craws and Arantulas. If Mario equips it, his attacks with both his jumping and his hammer increase by one if action commands are used. If the action command isn't used, the attacks deal no damage. This does not affect his partners' attacks, and its effects do not stack with other badges that allow Mario to attack multiple times, such as Power Bounce, though missing an action command still results in no damage.
