Version 3.6 Banners and Release Date

As mentioned in the Developer Radio during Version 3.5, players must clear Memory of Chaos Stage 12, Pure Fiction Stage 4, and Apocalyptic Shadow Stage 4 with a full-star record to unlock Anomaly Arbitration.

Players will need to form three separate teams and clear the trial stages first before accessing the final stage.

Once all stages have been cleared, you can take on the final stage. The Final Stage is considerably harder than the three previous stages, so prepare your strongest team here!
| Anomaly Arbitration Rewards | ||

Self-Modeling Resin

Interference Key

Lone Stardust

This is just a preview of the rewards and will be updated once the Anomaly Arbitration is released!

After clearing the final stage of Anomaly Arbitration, players will receive an Interference Key. This helps lock one Sub-Stat of the player's choice when using a Variable Dice and prevents that Sub-Stat from getting enhanced.
How to Get and Use Interference Key

Players can get Lone Stardust by clearing Anomaly Arbitration stages or purchasing them with Jade Feathers in the Priceless Jewel store.
These Lone Stardust can be used as currency to be used to purchase Cosmetic items in the store.

After clearing Anomaly Arbitration, players can claim limited-time Avatar Frames and medals based on their score when clearing the stage.
