God Tier and Deity Tier NFTs carry staking boosts. That means that your individual reward rate is increased by sum of the staking boosts on your NFTs with the cap of 25%. For example, if base rate per rebase is 1.0% and you have two God NFTs, your daily rewardRate is 1.0%*(1+10%), i.e. 1.0%*(1.1) = 1.1%. This translates to base APY of 4,001,871% and boosted APY of 11,481,026%.
