The various heroes players can battle within Thetan Arena are each represented by NFTs which players can buy, sell, and rent out to other players for profit. Hero NFTs possess many different attributes and aspects which differentiate them from one another: from stats such as health, damage, and attack & movement speed; hero & skin rarity; class — whether the tough and sturdy tank, the powerful marksman, or the stealthy assassin; and P2E modifiers like win bonuses — just to name a few! While all players start with a basic F2P hero, these heroes will restrict players’ ability to earn tokens at an accelerated rate, or participate in special events. These basic heroes also cannot be upgraded into Thetan Heroes. However, it is entirely possible to earn enough in-game currency with these F2P heroes to secure an NFT Hero, at which point the gameplay rewards really begin to roll in.
