## How to acquire Obsidian in Legend of Arcadia?
Obsidian, a valuable resource in the game, is primarily earned through Arena and World Boss modes. Players receive Obsidian rewards based on their periodic rankings in the Arena. However, in World Boss mode, all players receive the same reward after their first battle in each round. In Arena, victory depends on game mechanics, skills, and NFT hero combinations. Obsidian is mainly used for forging $ARCA.
With these two challenging game modes, you can earn Obsidian and advance your gameplay, enhancing your NFT heroes' skills and attributes. So why wait? Join the Arena and World Boss modes now and start earning Obsidian today!\
