Evolution item

An evolution-inducing held item is a specific type of held item that either has no other use besides, or is mainly used in order to cause, the evolution of a Pokémon. Many of these items also require for the Pokémon to be traded with another player, however, some only require the Pokémon to be leveled up. The item disappears after the Pokémon has evolved.
