Balance Adjustments
Balance Adjustments will happen for the game every 12 months and its goal is to provide new strategic choices to deck building.

Some combatants are also getting reworked for the game's long term health. This round have Cassius and Tressa among the others. The Save Data for these characters will be retained and accounts with affected changes are set to receive a Save Data editing ticket which will let you update existing Save Data.

Simplified Simulation Gameplay
The Simplified Simulation Gameplay lets you add multipliers to your simulatin runs. This will also consume the same amount of Aether as the multiplier you set for it but it will let you do that content less amount of times for the same rewards. For example, it lets you add an X2 multiplier to consume double Aether for 3 waves of simulation and also obtain twice the reward. This lets you complete the game's simulation daily content swiftly.
Upcoming Season 3 Updates
Chaos Assault
Chaos Assault is a true Roguelike content which features more difficult content and no Save Data will be saved after completing the content. In addition to the more difficult content, you'll also gain unique roguelike modifiers that are much stronger than the original chaos zone's modifiers such as fates that can remove the Used Card Pile system. This can effectively let players create an infinite loop of card combos in the right scenarios.
Completing Chaos Assault will focus on obtaining rewards such as Save Data editing tickets
Purification Protocol
Purification Protocol is a game mode that will feature 3 separate areas that will require a team for each area. The game mode features extra options such as requesting external help such as buffs during these long gauntlet of fights. Stress will also be a key factor in this game mode where mental breakdowns are more likely to occur while also featuring extremely difficult battles.
Combatant Challenge Missions
These are separate challenge missions for each combatant that makes you focus on that combatant's certain gimmik. Succesfully completing these missions will reward you with that combatant's stickers.
Growth Guide
