Experience-affecting items

Experience-affecting items are items that affect the amount of experience that a Pokémon gains in battle. There are three different experience-affecting items. They are, chronologically by their introduction, Exp. All, Exp. Share, and Lucky Egg.

Exp. All

If the player currently has the Exp. All in their bag, experience gained in battle will be divided evenly between the members of the player's party, as long as they are not fainted. This item is only available in Generation I.

Exp. Share

A Pokémon may hold the Exp. Share. When they are holding it, experience gets divided evenly among all party members holding this item and the Pokémon that is battling. Remaining experience is divided normally. One can be found in each game from Generation II onwards, and extra ones may be won through several in-game lotteries involving Trainer ID numbers.

Lucky Egg

In Generation III, Pokémon holding the Lucky Egg gain double the normal amount of experience they would have earned at the end of a battle. It may be obtained in Pokémon XD: Gale of Darkness by completing a side-quest mission or found held by wild Chansey in Pokémon FireRed and LeafGreen.

In Generation IV, Pokémon holding the Lucky Egg gain 150% of the normal amount of experience they would have earned at the end of a battle. Like in FireRed and LeafGreen, it is found held by wild Chansey. However, there is only about a 5% chance of Chansey holding a Lucky Egg.
