Update release

The Forbidden Catalyst update will become available on 12th November 2025.

Seasonal system details

• Each season will last for 9 weeks, split into 3 parts – early, mid, and late,
• Each part will bring something new – for example, story stages or new content,
• New Chaos will be added in every season,
• You can play the seasonal content only using save data obtained there, so you can’t bring your ‘normal’ saves there,
  • The seasonal data won’t be deleted once the season ends – you can keep using it in Simulation and Basin of Hyperspace
• The seasonal save data will be marked in a special way to make it easy to spot them compared to normal Chaos/Zero saves,
• Once the season ends, both the story and Chaos will be added to the ‘standard’ pool – so even if you miss a season, you won’t be locked out of the content.

New characters

Three new characters will be added to the game in Season 1 – Yuki, Chizuru, and Sereniel. But the stream focused on the first one—Yuki, who will be the first seasonal banner. Chizuru and Sereniel will become playable in mid and late phases of Season 1.

Yuki

Yuki is a 5-star Order Striker, and she specializes in doing AoE damage. Her special mechanic is Inspiration – whenever a card is moved to hand by an ability (by herself or by others – Nia or Cassius, for example, can do that easily), Inspiration will trigger additional effects like reducing the cost of the card or increasing their damage.
