Evolution items are special items used or held to trigger the evolution of particular Pokémon. Common examples include elemental stones, trade-held items, and location-related items, but the exact catalog depends on the generation. Some items are consumed when used, while others must be held during a trade or level-up. If an item does not cause evolution, check that it is being used on the correct species and that the game supports that method. Evolution items can be limited early in a playthrough, so consider whether you want to evolve immediately or wait until the Pokémon learns a desired move.
