Star Piece

Every wild place a Pokémon that may hold Star Piece turns up, best odds first. The odds are how often each of them appears there times how often it holds the item, added up for every one you can meet at the same time. Hold chances are from the game's files as of August 2026.

• Lead with Compound Eyes or Super LuckThe first Pokémon in your party, even a fainted one, turns a 5% item into 20% and a 50% one into 60%. At the best place above that takes Star Piece from 1 in 80 to 1 in 20 encounters.

• Catch it, do not steal itIn this game Thief and Covet only keep the item until the battle ends; your Pokémon does not leave with it. A caught Pokémon keeps its item, so throw a ball and take the item from it in your party.
• Check first with FriskA Frisk Pokémon names the foe's item when it comes in, so you only spend balls on the ones holding it. Put the Compound Eyes Pokémon first, fainted, and send Frisk in to battle.

You meet each of these once or on a special trigger, so you cannot farm them, but each one may hold Star Piece when you meet it.
