Simplifier

Simplifier is a badge in Paper Mario: The Thousand-Year Door. It can be bought from the Lovely Howz of Badges for 50 coins. If Mario equips the badge, all action commands are easier to use at the cost of receiving less SP from each successfully-inputted command. This applies to all moves, whether from Mario or his partners, including moves that require button presses at specific moments (such as Mario's jump or Goombella's Headbonk) or moves that require buttons to be inputted alongside a bar (such as Koops' Shell Shield or Ms. Mowz' Kiss Thief). Equipping multiple copies of the badge further makes it easier for action commands to be used while further lowering the amount of gained SP. The Unsimplifier badge does the opposite, making action commands harder while giving more SP in return. Equipping both of them at the same time cancels them out.

The badge's upside also affects Guard and Superguard action commands, loosening the input window by 1/120 of a second (1/2 of a frame).
