Every hero in Kaby Arena is unique and can be minted into NFTs, or are NFT themselves. Unlike traditional NFTs games, we give out free non-NFT heroes for all players at the beginning of the game. Player can start earning with the free heroes. They might earn enough $KABY to buy themselves the NFT or might be lucky enough to get new unique heroes from the drops during playing the game. Then, players can mint them into NFTs at any point of time using Kaby tokens. This design will solve the problem of high initial cost for players. They have the choice of minting only their strongest heroes instead of paying for each and every mediocre hero.
