Paper Mario: The Thousand-Year Door Cheats

Danger Mario
Make it so that Mario is in the danger position (5 hp or less), then equip him about 20 Power Rush badges, and with badges that attack all enemies, like Fire Drive and Multibounce. And be sure to KEEP him in the danger position. With this setup, Mario can kill almost all enemies in a single hit. For enemies such as fire enemies, or Chain Chomps, or enemies of that sort, whom your regular attacks might not work on, use an attack item, or a star power attack. And just to be on the safe side, bring a few life shrooms with you. This setup makes alot of parts of the game, including the Pit of 100 Trials, really easy.
