Mongens need Evolution Points to evolve to a higher Evolution Level. Users can exchange Evolution Item to gain Evolution Points for Mongens.
Each Mongen will receive specific Evolution Points when deployed in Adventure battle. Users can extract Evolution Point from Mongen to create Evolution Item. Or users can get Evolution Item by completing the daily quest, opening the chest, or purchasing it from others on the marketplace. Users can sell their Evolution Items on the market after converting them to FT.
