New Version 4.5 Story Content
Version 4.5 expands the Astropolis storyline with a new Trailblaze Mission and Trailblaze Continuance. Both pieces of content require Trailblaze Level 21 or higher and become permanently available after the update.
Trailblaze Mission: To Roll the Stars in Astropolis
The main Trailblaze Mission, “Astropolis — To Roll the Stars in Astropolis,” continues the larger Planarcadia storyline. Its central conflict centers on Astropolis's survival and the difficult choices shaping its future.
Players can access the mission permanently after Version 4.5 launches. The story can also be played early through Finality’s Vision during the version.
HoYoverse recommends completing “Planarcadia — In Ravages Does the Whistle Sound” before starting the new mission.
Trailblaze Continuance: The Zero-Dollar Strategy
The new Trailblaze Continuance is called “Astropolis — How to Lose Your Way to the Top: The Zero-Dollar Strategy.” It follows a very different premise: an enormous spending spree, with 20 billion and a three-day timeframe as part of the story.
Although the Continuance is permanently available, players are advised to finish “To Roll the Stars in Astropolis” first. You can also access it early through Finality’s Vision during Version 4.5.
Version 4.5 New Characters
Version 4.5 introduces Robin • Summeretto and Aventurine • Waveflair as two new 5-Star characters. They use different Paths and combat roles, giving players two very different options to build around.
| Character | Rarity | Path | Element | Combat Focus |
|---|---|---|---|---|
| Robin • Summeretto | 5-Star | Remembrance | Wind | Support, action advancement, Energy regeneration, team buffs |
| Aventurine • Waveflair | 5-Star | Elation | Quantum | Damage dealing, attack-count mechanics, Elation Skills |
Robin • Summeretto
Robin • Summeretto is a Wind Remembrance support character who uses the memosprite “Summer Songbirds.” Her kit focuses on helping teammates act more frequently while providing team-wide benefits.
She can advance a selected ally's action and restore Energy. She also provides several buffs, including effects that allow the team to ignore enemy DEF under certain conditions.
Her mechanics become more valuable when allies take actions repeatedly, making team activity an important part of her gameplay.
Aventurine • Waveflair
Aventurine • Waveflair is a Quantum Elation damage dealer built around the number of attacks made by the team. His mechanics allow him to access his Elation Skill during combat repeatedly.
Team attacks generate Fervor and Punchline. Fervor can enable an additional Elation Skill and strengthen his next one through Aha Instant.
When an enhanced Elation Skill is used, Aventurine consumes Fervor to deal additional damage.
New Light Cones and Trailblaze Fashion
Version 4.5 adds two new 5-Star Light Cones, two relevant 4-Star Light Cone sources, and a new headwear item.
The two featured 5-Star Light Cones are “Rise and Sing” for Remembrance and “Summer Rides the Surf” for Elation. Players can obtain both through their respective Brilliant Fixation Light Cone Event Warps.
A new 4-Star Elation Light Cone called “A Little Getaway” appears in the Version 4.5 Light Cone Event Warps. It will enter Stellar Warp in Version 4.6, but it will not be added to Departure Warp.
The Hunt also receives a new 4-Star Light Cone, “Race to the Horizon,” which can be obtained from the Overdrive: Whirlwind Grand Prix event.
Players can also add a new cosmetic item, “Aw, Look Up Here,” to their Trailblaze Fashion collection. Players can purchase this headwear with Stellar Jade.
For fans who also follow Honkai: Star Rail collectibles and character merchandise, Animon Life tracks official merchandise releases alongside major game updates and character launches.
New Astropolis Areas
Version 4.5 opens three major locations in Astropolis: Astropolis Central District, Lodestar Tower, and Skycall Aery. Each area represents a different part of the city’s social and economic structure.
Astropolis Central District
The Astropolis Central District houses the headquarters of the Interastral Peace Entertainment. Beneath its entertainment-focused image, however, the district also serves as a place where different IPC interests compete for influence.
Lodestar Tower
Lodestar Tower represents the working side of Astropolis. It is described as the behind-the-scenes area where workers create the systems, products, and spectacles that support the wider city.
Skycall Aery
Skycall Aery sits atop Lodestar Tower and serves as a central point in Astropolis. Under unusual circumstances, it can even function as the heart of the wider Pan-Cosmic Trade System.
Version 4.5 Events and Rewards
The main Version 4.5 events include the Whirlwind Grand Prix, Minuscule Great Adventure, and Gift of Odyssey. Each event offers a different type of gameplay or login-based reward.
Overdrive: Whirlwind Grand Prix
The Overdrive: Whirlwind Grand Prix begins after the Version 4.5 update and ends on September 28, 2026, at 03:59 UTC+8.
The event introduces a new racing competition in Astropolis inspired by the Phantasmoon Games. Players compete as teams, with the winning side pursuing the title of “God of Traffic (Laws).”
The event requires Trailblaze Level 21 or above. Players can access it early through Finality’s Vision, although completing “The Zero-Dollar Strategy” first is recommended.
Minuscule Great Adventure
Minuscule Great Adventure runs from September 12, 2026, at 12:00 server time until September 28 at 03:59 UTC+8. Players form a hero team and progress through multiple combat stages.
The event is available to players at Trailblaze Level 21 or higher.
Gift of Odyssey
Gift of Odyssey rewards daily logins, with Star Rail Special Pass ×10 available after seven check-ins. This makes the event one of the straightforward ways to collect additional Warp resources during the version.
Voracity Corrosion and New Combat Content
Voracity Corrosion introduces enemies that can recover HP after receiving fatal damage. These enemies are connected to the awakening power of the ancient Aeon of Voracity.
Affected enemies gain the Voracity effect. Instead of being defeated immediately when they receive fatal damage, they restore part of their HP.
Players can counter this mechanic by repeatedly dealing damage to reduce the enemy’s Max HP. Once the suppression reaches the required level, the enemy can finally be defeated.
The affected enemy lineup includes “Lighthouse,” “Astropolis Sentinel,” and “Unwaning Ageless Immortal.”
Anomaly Arbitration
Anomaly Arbitration receives a new high-difficulty phase called “Return of the Legion.” The mode offers rewards such as Lone Stardust, Interference Keys, Self-Modeling Resin, and limited-time avatar frames.
Apocalyptic Shadow and Pure Fiction
The permanent combat modes also receive new stages during this period. Due to the shortened Version 4.5 schedule, these stages run for five weeks.
Apocalyptic Shadow: Celestial Lupine runs from August 31, 2026, at 04:00 to October 5, 2026, at 03:59 server time. Breaking an enemy with Steadfast Safeguard removes control debuffs from allies and activates their Ultimates. Enemy Skill DMG taken increases by 25%, while Elation Skill DMG increases by 15%.
Pure Fiction: Domain Genesis runs from September 14, 2026, at 04:00 to October 19, 2026, at 03:59 server time. Every time Punchline is gained, allies also receive 2 Grit Value.
The next Memory of Chaos phase becomes available after Version 4.6 begins.
Dialogue Speed-Up and Furbobocom Updates
Version 4.5 adds a Dialogue Speed-Up option to speed up story progression. Players can activate the feature from the top-right corner of supported dialogue interfaces.
The setting speeds up text, voice lines, and other dialogue performance elements. It does not apply to story cutscenes or combat animations.
At launch, the feature supports missions from Versions 4.0 through 4.5, dialogue in the Planarcadia and Astropolis areas, and newly added missions. Earlier content will receive support gradually.
Furbobocom Press Affairs
Furbobocom receives a new Press Affairs management feature as players progress through the Version 4.5 Trailblaze Mission. Players can send furbos to investigate reports, create TV programs, and interact with newsroom staff.
A new Energy Sensor gadget is also available. It reveals the location of one Basic Treasure on Astropolis-related maps. Players can obtain it by increasing their Furbobo Freebies level.
Version 4.5 additionally introduces new readable items, Messages, discs, Achievements, Data Bank entries, and loading-screen text as players advance through the story.
Version 4.5 Adjustments and Bug Fixes
The update also contains a large set of technical fixes covering characters, combat, missions, environments, audio, UI, and special gameplay modes.
The update fixes visual issues affecting characters such as Himeko • Nova, Gilgamesh, Jingliu, Cyrene, and Yao Guang. The update also corrects several enemy models, animations, cameras, and combat effects.
Combat fixes include issues involving Action Order displays, ability interactions, target selection, Assist Skills, and abnormal combat progression.
The update also resolves multiple issues in Currency Wars, including problems involving Destiny Components, Independent Bonds, character abilities, Action Order, Ultimate counts, and equipment effects.
Several issues in Imagenae: Holy Grail War, Fate/stay night, Antigraft Brickbuster, Apocalyptic Shadow, Pure Fiction, Memory of Chaos, and Cosmicon, Roll On Again! are addressed as well.
English voice-over and text receive additional corrections, including dialogue, subtitles, character stories, tutorials, item descriptions, enemy information, and mission text. Similar localization fixes are included across 13 supported languages.
