Stella Sora Version 1.5 Now Live With New Trekker, Disc, Events

🌙 Stella Sora 1.5 Is Live — New Umbra Picks, Chapter 6, and a Full Event Sprint

Version 1.5 is now live in Stella Sora, bringing a new ★5 Umbra Trekker, a new ★5 Umbra Runic Disc, a major story drop with Chapter 6, and a packed calendar of time-limited activities stretching from mid-January into late February. The update leans hard into Umbra-focused progression, pairing recruitment incentives with multiple event tracks that reward consistent play rather than one-time clears.

Meaning shift: Version 1.5 quietly changes the “best way to progress” mindset. Instead of logging in only for banners, the patch pushes players to treat events like a parallel progression lane—because key rewards, discs, and upgrade materials are now tied to ongoing participation and milestone loops.

⭐ New Trekker and Runic Disc

Version 1.5 introduces two new ★5 Umbra additions, both tied to limited-time recruitment.

🗡️ New ★5 Umbra Trekker: Firenze

Firenze is available from the event-limited banner “Mirroring the Jade’s Ideal.” If you’ve been building Umbra-centric teams or want a fresh headline unit to anchor upcoming vulnerability cycles, Firenze is the main pickup target of this launch window.

💠 New ★5 Umbra Disc: Wisteria Dream

Wisteria Dream is available from the event-limited banner “Reverie in Fragrant Tea.” This release strengthens Umbra disc options and signals that 1.5’s combat direction is emphasizing Umbra setups across both story and event content.

📖 New Story Content

Main Story Chapter 6: Miracle of a Flicker

Release: Jan. 12, 2026 (permanent after maintenance)
Chapter 6 rolls out in two halves:

First Half: available after Jan. 12 maintenance
Second Half: available Jan. 19, 2026 after maintenance

Narratively, Chapter 6 escalates into a crisis driven by loyalty, delusion, and extremism—an ally spirals into obsession, then returns as a tyrannical force commanding an army of plants and igniting open conflict. The story frames you as the decisive stabilizing force: you’re not simply reacting to chaos, you’re expected to reshape the outcome and reclaim “peace” as a deliberate choice.

The Nova Times — New Chapters #08: Captive of Truth

Unlock timing: Permanent after Jan. 26, 2026 21:00 (UTC-7)
This chapter positions itself as a tonal pivot—twilight giving way to dawn—suggesting a truth-reveal beat that complements Chapter 6’s war escalation and resets momentum heading into the next event wave.

🎯 Main Story Update Event: Miracle of a Flicker

Event period: Jan. 12, 2026 after maintenance – Jan. 26, 2026 12:59:59 (UTC-7)
Event Shop / Exchange: Jan. 12, 2026 after maintenance – Feb. 02, 2026 19:59:59 (UTC-7)
Requirement: Authorization Level ≥ 5

This is the patch’s primary reward engine. You’ll be defending against Intelligent Plants while completing missions to earn Expense Receipt, which fuels the Event Shop.

Key rewards to prioritize

★5 Runic Disc: The Bud of Change
Honor Title: Miracle of a Flicker
Stellanite Dust
Sprout Ticket and Cerulean Ticket
Trekker/Disc tier-up materials and upgrade resources

Progression strategy that actually works

Treat Expense Receipt like your main currency goal, not a side bonus
Clear mission chains early so you can “coast” on shop farming later
Plan your strongest teams around event pacing—burnout usually happens when players delay and try to rush in the last 48 hours

⛏️ Lucky Treasure Shovel

Event period: Jan. 12, 2026 after maintenance – Feb. 02, 2026 12:59:59 (UTC-7)
Requirement: Authorization Level ≥ 5

Lucky Treasure Shovel is built around exploration loops:

Use Treasure Shovels to uncover hidden rewards with your Trekkers
Accumulate points to complete quests
Earn Stellanite Dust, Expense Receipt, and additional materials

Practical tips

Spend shovels consistently instead of hoarding them
If you’re chasing The Bud of Change quickly, treat this as supplemental receipt income
Point-based events reward routine—small daily progress beats one large grind session

🌪️ Event Update: Cataclysm Survivor

Event period: Jan. 12, 2026 after maintenance – Feb. 02, 2026 19:59:59 (UTC-7)
Requirement: Authorization Level ≥ 10

Cataclysm Survivor is a milestone-based challenge where clearing zones generates points toward rewards.

Milestone rewards include

Stellanite Dust
Defender’s Medal

Enemy vulnerability info

Zone 1: Umbra, Ignis
Zone 2: Umbra, Terra

This is a major signal that Umbra investment remains valuable across the entire 1.5 cycle, while Ignis/Terra coverage becomes your stability layer depending on which zone you’re pushing.

🧠 How to Get the Most Out of Version 1.5

If you want power fast: prioritize Miracle of a Flicker missions for Expense Receipt, then lock in The Bud of Change early
If you want long-term efficiency: pace Cataclysm Survivor milestones and shovel events daily instead of grinding late
If you’re planning future pulls: treat Jan. 26 as the pivot point—Mistique and Witch’s Swing arrive alongside multiple short-window events
If you’re pushing Boss Blitz: make sure your Terra/Lux options are ready before Blade of Jade becomes your wall

Players looking to accelerate their Version 1.5 progression can explore verified Accounts to jump straight into endgame-ready rosters, book professional Hourly Services for event routing and team optimization, or use trusted Boosting services to efficiently clear milestones, event missions, and high-pressure boss content.

With Umbra-focused banners, a two-part Chapter 6 rollout, and layered event loops that reward consistency, Version 1.5 is best approached as a full season plan—not a one-week sprint.
