Bestow

Bestow gives the user's held item to the target. It will not work if the target is already holding an item or is behind a Substitute. Mail cannot be transferred. Items bestowed upon wild Pokémon are permanently lost if the Pokémon is KO'd, but items lost in Trainer battles are returned. All held items in wi-fi/linked battles (including Battle Tower/Subway/Maison) are returned to their respective owners at the end of a battle. Pokemon with the ability Sticky Hold cannot have their held item removed. The Griseous Orb cannot be removed from Giratina; Type Plates cannot be removed from Arceus; Drives cannot be removed from Genesect; and Mega Stones cannot be removed from their respective Pokémon.
