Move Relearner

The Move Relearner is a NPC who will teach a Pokémon a move that they learned but forgot in exchange for a Heart Scale. He will not teach forgotten moves that were learned by breeding, TM/HM or Move Tutor, or in the case of Smeargle and Ausitto moves that were previously learned via Sketch but forgotten. Heart Scales can be found at the Game Corner in Treader Town, mined in the Secret Base, or held by wild Luvdisc.

The Vesryn Move Relearner is located at Treader Town in the house that is next to the Pokemon Center

The Aroma Move Relearner is located in the top floor of the Aroma Secret Base in Carinae Town.
