SS6.4 New Animus

Thalos (Constant)

Thalos is a new Apex SSR Animus and a defensive Supporter. He can take damage on behalf of his allies and revive several turns after falling, which gives the team a stable layer of survivability. He can also use [Infernal Flame] to continuously erode enemies, so he balances damage mitigation with sustained pressure.

The [Prowess Up] event runs from 2026/11/04 03:00 to 2026/12/02 02:59 (UTC-5). Activate Thalos's Anima Prowess to receive rewards including Exclusive Lattice: Thalos, Red Shadowprint and Module Essence.

Summit Arena HYPA Season

The Summit Arena HYPA Season runs from 2026/11/04 03:00 to 2026/12/02 02:59 (UTC-5), and it comes with brand-new Affinity restriction rules. Victories award more points, and defeats in ranks below Platinum no longer deduct points. That makes it a safer season to push for the Mythic rank.

Affinity Restriction: choose 2 Anima Affinities and 1 Apex Affinity to build your Affinity combination. In battle, you can only select Animuses that match that combination.

Seneschal: Chaku

Seneschal: Chaku is a new feature built to save you time. It has three parts:

1. Daily rewards: quickly claim Union check-ins, daily Quests and Hyper Kernel tasks.
2. Favorite Dungeons: set up to 5 preferred dungeons for easy consecutive battles.
3. Shop Assistant: buy the items you've set in the Summon Shop, Union Shop and Arena Shop with one tap.

SS6.4 Limited-Time Events

Dates marked SVT are given in the server time used in the official notes.

• The Heuristic Pit (2026/11/04 03:00 - 2026/11/11 02:59 UTC-5): form 5 Animus competitive teams and rack up match wins. One round of auto-matched battles is held daily from 23:00 to 09:00 (UTC-5), and each team fights 10 battles per round. Accumulated wins earn resources such as Crystal Blueprint Fragments and Hydra Crystals.
• Ultimate Crystal Protocol (11/05 04:00 - 11/12 03:59 SVT): purchase Support Boxes to receive bonus EnergeZ and unlock extra rewards such as Reassembly Chip Fragments, Crystal Blueprint Fragments and Shaping Cubes.
• Modules Recycle Protocol (11/05 04:00 - 11/12 03:59 SVT): recycling Modules that meet certain conditions gives their base recycling value an additional multiplier.
• EWS 2026 Global Finals (2026/11/09 15:00 - 2026/12/22 14:59 UTC-5): choose the region you support and vote for it. Complete your daily votes to earn Decisive Star Emblems, and as a region's vote heat builds up, more decorative items and resource rewards unlock.
• Wishbinder Gift (11/12 04:00 - 11/19 03:59 SVT): summoning Animuses in Permanent Summon grants Wishbinder Pts. New reward tiers at 400 and 500 pulls have been added, and rewards include Perfect Lattices, Quantum Cipherboxes (Kokardi, Qano, Celince), Wishbinder Gift Resource Boxes, Prism Dice and random Crystal Blueprints.

The [Restart Time] event also got an upgrade. [Hyperlink Reboot Protocol] now grants the Xuan Li outfit [Tidal Shadow] at a specific level. If you already own the outfit, claiming it converts it into Hydra Crystals.

SS6.4 Optimizations

• Main Quest: dungeons now support consecutive battles within the same section.
• Hyper Kernel: the Stability purchase limit changed. You can now exchange for [Hydra Crystal ×100] up to 10 times instead of 5, after which you can continue exchanging for [Hydra Crystal ×200].
• Overall game stability was improved.
