Heroes are the fundamental units for a player's army, consisting of individual stats and abilities. Every army would need a Hero to lead it. In order to create a Hero, players will have to train and recruit Heroes into their military units using time and resources. These Heroes can have different appearances, names, stats, and durability and are minted on the players' behalf.
The lifetime of a Hero is limited; for every fight, a hero loses one durability unit. When a Hero reaches the end of his life, Legacy NFTs can be earned, which have increased utility as a reward for the player's past gameplay and the XP earned.
