The Noble Knights collection was created by one of the most renowned artists in the world. 4,444 Knights will be dropped, with their holders earning passive income just for holding. Level 1 Knights earn 1% ETH rewards, while Level 2 Knights earn 4% rewards, and the only way to upgrade to a level 2 Knight is by battling another holder. Winners get upgraded, but losers have their NFT burnt, meaning this is the first deflationary collection in the market.
