==In Explorers of Time and Darkness==
If one were to have two Pokémon-specific items, known as [[exclusive item]]s, they could trade it for a rarer exclusive item of that species. For some species, there is a third rank, where the rarer exclusive item must be traded with the two other exclusive items in order for the rarest of the exclusive items for that species to be received. However, this only works if the species has more than one exclusive item.
Exclusive items can be identified by the stars in their item summaries. The number of stars represents the rarity of the item. It also shows which Pokémon the item can be used with.
