The reference to "(45 игр)" suggests a specific version or a count related to a collection or a "Piece" (accessory part) that provides a high boost to certain stats, often at a cost or "dishonest" penalty. In the context of One Piece Odyssey :
: It is an Accessory (Piece) that players can equip to characters like Luffy or Zoro.
: These "Concentrator" pieces typically increase ATK (Attack) or CRI (Critical Hit Rate) significantly.
