A: Defina Mystery Box features 28 different heroes, each with unique background stories and skills, belonging to one of four factions; Prometheus' Fire, Ouroboros, Thoth's Book, or Athena's Aegis. Heroes are randomly generated, with different rarity, attributes, skills, and elements. The hero levels in descending class and rarity order are SSS, SS, S, and A. To start playing the Defina game, you will need at least four different heroes to form a team. When a Defina Mystery Box is opened using a small amount of BNB, this box is burned to create a Defina Hero NFT.
