What is Codex Lost?

This single-player, third-person action RPG takes place in a ruined fantasy world after magical books are stolen. You explore fields, tunnels, and ruins, gather materials from defeated enemies, and craft elemental spells while choosing equipment and upgrading stats. Combat emphasizes deliberate attacks, dodging, and parrying.
