# NFT Staking

Players can stake their hero NFTs to earn rewards in HRI token; the earning rewards are calculated in APR. The price of every hero will be evaluated by the NFT mint price, tokens used for level upgrades and skins.

* 1 Hero Price = Hero Mint Price (0.25 ETH) + HRI Tokens used for Level Up & Skinning.
* 1 Hero APR (%) = Multiplier ^ Hero Level \* 100
* Multiplier = 3.2
