A Spite Pouch is an item that appears in Paper Mario: The Thousand-Year Door.
Spite Pouches are small, orange bags with some powder on the inside of it.
When a Spite Pouch is used, Mario or his partner is inflicted with the Payback status that counterattacks direct damage to opponents and inflicts half the damage toward them. For example, if Mario uses a Spite Pouch and gets attacked directly by a Spiked Goomba, he will deal 1 damage back since it's attack is 2. However, the Spite Pouch will not counter indirect attacks such as magical spells from Magikoopas.
