# Core

In Code Sekai, the gameplay revolves around transforming your ***NFTs*** into in-game characters. Deploy them on expeditions to explore the dungeon tower, where you'll encounter enemies, events, and valuable rewards.

After each expedition, your characters enter a maintenance phase for recovery. You can plan your next adventure and see the results, including collected rewards and new equipment.

Discover rare gear like ***Epic, Legendary*****,** or ***Mythic*** items to enhance your team's strength. Players can equip them or sell them on the marketplace for profit.

Transfer, deploy, collect, and optimize your team to experience the idle-RPG gameplay of Code Sekai.
