2) Battling and Customization. You can coins earned from staking to battle other NFTs. There is a 50/50 chance of winning each battle. Winning a battle grants you Battle Power and 75% of the coins used for the battle. As you increase in Battle Power you will unlock customizations for your Windam. You will be able to customize its weapons, arms, legs, feet, head and more. These customizations will cost the coin earned from staking. You will also be able to change the name of your NFT.
As your BP level increases vs you opponent the chances of winning also increase. However the cost of each battle will increase proportionally to the difference in your and your enemies BP. The amount of BP earned also changes according to this difference.
This should be a take in two NFTs + token amount and spit out two NFTs + tokens. Not an actual game.
3) Marketplace where they can spend the token earned from staking to purchase different customization options
4) Pushing the updates to block to update the NFT after customization.
