# 3.1 Hero NFTs

Each hero in WIN NFT HERO has his or her own position. Both tanks and attackers are indispensable in winning battles. Heroes of the same class or gene will form bonds, which will substantially boost the squad's performance in battles. Hero NFTs consist of five parts: quality, attribute, class, skill, and bond.
