This is a NFT contract with the Token URI being generated on-chain. Learnt the use of Chainlink VRF to produce random numbers to change token URI on-chain for the NFT.

Steps to test it:

1. Deploy the contract and verify it (I have used Amoy Testnet)
2. Call the mint function to mint the Warrior NFT
3. Call the train function to generate random numbers for the Warrior attributes.

P.S. : You need to setup Chainlink's VRF for this contract
