Square of Devil is a 6-minute event where players battle waves of enemies to earn experience and spirituality resources. This event does not drop items but serves as a key way to gain EXP and gather resources needed for spiritual advancements.

Additionally, if your guild members are strong and consistent throughout the event, you will also gain reputation once the event is over. Participating in Square of Devil regularly is crucial for leveling up efficiently and strengthening your character’s spiritual power while also contributing to your guild’s overall progress.
