Boundary

The Boundary, commonly called sky levels by players, is a feature available to reawakened characters. Boundary levels reward players with a permanent increase in their Spirit stat, an attribute that lets players deal more damage and receive less damage relative to the opponent's Spirit. They also allow players to learn new skills and passive skills that permanently increase their defenses, skill damage, Critical Hit ratio, HP and more. Some areas and some dungeons have specific Boundary level requirements.

Overview
Players that have reawakened can unlock their Boundary once they enter Primal World. There they can talk to the Arcane Sky Envoy Yanna to unlock their first Boundary of Arcane Sky. Every time a player reaches the maximum level of each Boundary, they can talk to the next Sky Envoy to unlock the next Boundary. Players that have reached Arcane Sky X will need to reawaken for a second time before they are able to break the Boundary to move to Mirage Sky I. Each Boundary has 10 levels and players can check their Boundary in their character's window by pressing the C key in-game.
