A Summoner Ball is a special Poké Ball, native to Napra that is not used in the traditional sense. It is made of prismatic crystal, and does not catch Pokémon during battle. It allows the Pokémon to have freedom to roam in the wild, as long as the Pokémon agrees to help the trainer during battle when it is called through the prism. The trainer must defeat the Pokémon they wish to create a pact with, and then wait for it to come to and show it the object. The ball sends the Pokémon the request for partnership telepathically, and if the Pokémon agrees, it will willingly reach out to come in physical contact with the ball. This heals the Pokémon completely, and encourages it to continue on with its life.
