Maintenance and Pre-Download Details

Pre-download begins on 2026-09-28 at 10:00 (UTC+8). Required storage space varies by platform:

Platform	Required Space	Actual Package Size
PC	46 GB	26 GB
Android/iOS	20 GB	13 GB

If your device lacks sufficient space, pre-download may not be possible. The update maintenance will not complete without enough reserved space. Extra space used during resource merging is automatically freed after maintenance.

How to Pre-Download

• PC: Click "New Version Pre-download" below the Start button on the launcher.
• Android/iOS: Tap the "Pre-download" button on the title screen or in-game Terminal.

You can continue playing while pre-downloading. The process can be paused anytime. A stable network connection is recommended.

Tiered Client Resource Downloads (Limited Test)

Version 3.7 introduces a limited test for tiered resource downloads. PC (official launcher) and all iOS/Android devices will gradually gain access after the update. During Version 3.6, some PC users may receive a launcher update, but the feature goes live only after 3.7.

• Players without test access will default to High-Definition (HD) resources.
• Test participants can adjust resource tiers based on their needs.
• On iOS/Android, only a portion of resources will be pre-downloaded; the rest downloads after the update based on the selected tier.

New Resonators and Weapons

Two new 5-Star Resonators join the roster:

• Hsin (Electro/Rectifier) — obtainable via the [As Full as Tonight, Forever] Featured Resonator Convene.
• Suoming (Electro/Sword) — obtainable via the [Nine Deaths, One Unbent Heart] Featured Resonator Convene.

Their signature weapons are also arriving:

• Blooming Jadehaven (Rectifier) — from the [Blooming Jadehaven] Featured Weapon Convene.
• Unspoken Rue (Sword) — from the [Unspoken Rue] Featured Weapon Convene.

Banner phase durations and pity details are not stated in official materials. Check in-game Convene details after the update.

Should You Pull?

Both Resonators share the Electro element, which may appeal to players building mono-Electro or reaction-focused teams. Hsin is a Rectifier user, while Suoming wields a Sword. Without official kit details, it's too early to judge meta impact. F2P players should wait for community testing before committing Astrite. Low-spenders may consider prioritizing one banner based on weapon type synergy with their existing roster.

New Region, Echoes, and Story

The Simulacrum Nexus of Mengzhou is a new area containing multiple subregions: Heartscape Labyrinth, Heart of Flames, Heart of Frost, Heart of Bloom, Heart of Stillness, Heart of Ruin, and Heart of Appearance. Access it during Main Quest Chapter IV Act IV, "Simulacrum of the Heart."

New Echoes include Formrender, Soulfrayer, Skywatch Lancer, Bloomburst Puppet, Jade Nether Serpent, and one new COST 4 Echo. Three new Sonata Effects arrive:

• Heart of Sworn Vigil (5-piece set)
• Flash of Electric Reflection (5-piece set)
• Flower of Tinged Yearning (5-piece set)

New Tacet Fields and a Tacet Discord Nest are also added. The main story continues with Chapter IV Act IV, plus a new Tales Quest: Moonlike Heart, Mortal Longing (requires completing the new main quest).

Gameplay Optimizations

Several quality-of-life changes are coming:
