Return Postage

Return Postage is a badge in Paper Mario: The Thousand-Year Door. It is the reward found in a treasure chest after reaching the 100th floor of the Pit of 100 Trials and defeating Bonetail. If Mario equips it, enemies who come directly into contact with him while attacking are damaged by half of what they dealt to Mario. This applies to exactly what Mario received as damage, meaning that guarding could reduce the damage that the enemy takes.
