## Rarity Card NFTs

This NFT Collection interacts with your Personality NFT. It allows you to Upgrade or Downgrade your Personality NFT's Rarity and Yield.

### Why you might want to increase Rarity

You can build an income by sharing your discount code. At some point, as your sales grow, it will be beneficial to increase your Rarity. This will increase your yield income. Additionally, it will make your  Personality NFT more valuable.

### Why you might want to decrease Rarity

If you don't intend to share the project with others, it might make more sense to downgrade. When you downgrade your Rarity, you'll be earning the difference between the Rarity Level you are buying and selling.&#x20;
