Illuvium: Arena is a crypto auto-battler video game in which you create a deck of cards, including creatures called Illuvials and other powerups, and place your Illuvials and yourself in the battle area. There, you fight the enemy player and their Illuvials. Overall, it is a fun experience fighting alongside the various Illuvials against the enemy and their Illuvials. Each Illuvial has unique stats and elements that can either give them a boost or a penalty while fighting, kind of like Pokemon.
