# Step 9. Pets, Friends, Party, and Blood Alliance The newly added pet system allows the other projects’ NFTs to be used in Klay Kingdoms, and Klay Kingdom's own pet NFTs will also be minted. When you connect a wallet that has specific NFTs to your game account, you can use a pet that matches each NFT. Benefits, such as buffs, are given through pets. The friend and party features will enable you to enjoy playing with other players, and we will open blood alliance systems that even continue through PvP zones. A blood alliance is only available when you can prove royal patronage. Royal patronage can be proven by possessing KINGs NFTs. If the blood alliance master stakes a KINGs NFT to his/her alliance, the maximum number of members can be increased up to 20. However, when staking a Legendary KINGs NFT, the maximum number will increase to 22 thanks to the Legendary benefit. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
