Obtain from Official Mail Distributions
Cube Keys may be distributed by the developers for various reasons, such as commemorating developer notes or special occasions. Some mail rewards have a limited claim period, so be sure to collect them before they expire.
How to Use Cube Keys
Used to Claim Rewards
You must consume a set number of Cube Keys to claim rewards from Elite Monsters, Field Bosses, Boss Challenges, and Dungeons. Rewards cannot be claimed without using Cube Keys, so be sure to manage your remaining supply carefully.
