Paper Mario: The Thousand-Year Door/Star Pieces

Like in the previous game, the Star Pieces in Paper Mario: The Thousand-Year Door are mainly found through flippable panels, in hidden areas, or by completing side-quests. The panels can be flipped by Spin Jumping (possible after Mario finds the Super Boots in Chapter 2) near them. Mario can also find panels by swinging his Hammer against the ground. There are 100 Star Pieces total. Mrs. Mowz is capable of telling Mario if there is one in the area with her field ability, and Merlee in Rogueport Sewers can give Mario clues as to where they are. A character named Dazzle in Rogueport Sewers trades Badges for Star Pieces.

Dazzle

Star Pieces can only be spent to Dazzle, a trader found in the sewers of Rogueport after Chapter 1 is completed. Dazzle has many badges, many of which can only be found here and are extremely powerful tools.

Badge name	Cost	Badge description
Attack FX Y	1	Changes sound effects of Mario's hammer.
Chill Out	2	Mario is not impacted by a First Strike from enemies.
Pretty Lucky	3	Sometimes attacks will miss Mario.
Happy Flower	4	At the end of each turn, there is a 50% chance to heal 1 FP.
Happy Heart	4	At the end of each turn, Mario has a 33% chance to heal 1 HP.
Happy Heart P	4	At the end of each turn, the active Partner has a 33% chance to heal 1 HP.
Item Hog	5	Raises the chance that enemies will drop items after battle.
Heart Finder	6	Raises the chance that enemies will drop HP after battle.
Flower Finder	6	Raises the chance that enemies will drop FP after battle.
Peekaboo	7	Enemy HP will always be revealed, regardless if they have been Tattled.
Quick Change	8	Swapping a partner in battle does not cost a turn.
Flower Saver	10	All of Mario's attacks cost 1 fewer FP, but not less than 1.
Flower Saver P	10	All of the Partners' attacks cost 1 fewer FP, but not less than 1.
Power Plus	15	All of Mario's attacks deal 1 extra damage.
Power Plus P	15	All of the Partners' attacks deal 1 extra damage.

Each of these badges have significant benefits and drawbacks, but generally Peekaboo, Chill Out, and Flower Saver P will be among some of the most useful to acquire. Peekaboo's health revealing mechanic helps manage and prioritize in battle significantly, while Chill Out prevents excessive damage towards the heroes. Flower Saver P will help keep Mario's Partners' attacks from draining FP too quickly, allowing for their more damaging or protective moves to be used more often. Some strategies for boss fights will also utilize Quick Change.
