Move Tutor
Zisu acts as a Move Tutor, teaching new moves to the player's Pokémon for a fee. Moves taught outside of a Pokémon's level-up moveset require a Seed of Mastery in order to be mastered, a service also provided by Zisu.
Certain moves will only be available for teaching after reaching a certain rank.
