Upgrading Your Rarity
You can Upgrade your Personality NFT's Rarity at any time by purchasing a Rarity Card and selecting the Upgrade option.
The Upgrade will Swap the Rarity and Yield.
Your Personality NFT will be upgraded, and your Rarity Card will be downgraded. After the Upgrade, your Rarity Card will show the lower rarity, and you can sell it on OpenSea.
Then your Personality NFT will automatically begin earning the higher Yield.
