Illuvium is an upcoming Ethereum-based role playing game where users can earn through gameplay. It uses Immutable X, the layer 2 scaling solution for NFTs on Ethereum, which provides gas-free transactions. Players can capture non-fungible token (NFT) creatures called Illuvials, which become more powerful as they win battles. Players earn ILV, the in-game token, as reward.   Players can sell and trade their Illuvials on Illuvium’s NFT marketplace IlluviDEX.
