Honkai: Star Rail 4.5 Guide: Robin, Himeko and Rin Tohsaka
Honkai: Star Rail 4.5 Content and Cycle
Dates and the five-week cycle
Version 4.5 went live after maintenance on August 26 and lasts five weeks, one week shorter than usual . A shorter cycle means events and banners overlap more, so plan Stellar Jade one version ahead instead of realising mid-patch that you are short.
Amphoreus-adjacent new area and story
The story moves to the Thousand-Star City , with the Trailblaze Mission "A Wager of a Thousand Stars" and a Trailblaze Continuance titled "Becoming a Billionaire Starts With Not Charging" . Mission names can be verified in game.
Zenless Zone Zero collaboration teaser
During 4.5, HoYoverse confirmed a collaboration with Zenless Zone Zero for later this year, with details pending . That affects long-term Jade planning, not this patch.
Honkai: Star Rail 4.5 Robin and the Remembrance Path
Why the Path swap matters
Robin's SP form is not a costume change. She moves onto the Remembrance Path, which fundamentally reshapes her combat role . Remembrance mechanics differ from Harmony, so old Robin team-building notes do not carry over.
Build direction
As the first-half centrepiece, Robin wants her Light Cone and relics to keep the Path mechanic running before you chase crit stats . Farm her materials early; a five-week patch does not leave much room for trial and error.
Pull advice
Pull her if your roster lacks a Remembrance unit, and wait for the second half if you already have a Remembrance core . In patches packed with collaborations and reruns, filling a role beats chasing Eidolons.
Honkai: Star Rail Himeko and Aventurine SP Units
Himeko's mech summon
Himeko's 4.4 form is a Fire Erudition unit whose core is summoning the mech Trailblazer-Chaser; her Skill restores assist skill uses and raises team damage, while her Ultimate fires an Overclocked Particle Beam and an Orbital Annihilation Pulse . She is a crowd-clear unit, and Skill timing matters more than her paper stats.
Aventurine's Elation form
Aventurine's SP form arrives in the 4.5 second half as a limited 5-star on the Elation Path with Quantum damage. Elation mechanics differ from Preservation, so do not reuse his old shield gear.
How the two fit together
Himeko handles group pressure and clears, while Aventurine's SP form runs an Elation damage line, so the choice depends on whether you need AoE or single-target damage. In two-wave environments such as Memory of Chaos, the AoE slot holds value longer.
Honkai: Star Rail Rin Tohsaka and Collab Units
The gem energy mechanic
Rin Tohsaka is the Fate collaboration limited 5-star, a Quantum Erudition unit whose core is gem energy: her basic attack supplies steady single-target damage, her Skill spends energy for single-target and AoE Quantum damage, and her Talent boosts team crit while accumulating gem energy .
Ascension materials and level 80 planning
Her ascension materials fall into three groups: universal progression materials, element and role materials, and limited special materials. If you only plan to reach level 80, prepare 70% of the materials plus 1.6 million Credits to avoid overshooting.
Collab units do not always return
Fate collaboration limited characters follow the same window problem as other limited units and may not rerun after the collaboration ends . If you plan to build one, farm the materials inside the window.
Honkai: Star Rail Memory of Chaos
The two-wave structure
Memory of Chaos changed to a single-position, two-wave structure from version 1.5 onward across all floors. Squads must keep damage flowing between waves instead of clearing a floor with one burst.
Reading the Turbulence buff
Each rotation carries a Memory Turbulence style buff, so check the current buff before choosing carries and supports. The wrong buff direction stalls the timer even with strong panels.
Team direction
Put AoE carries into two-wave environments and single-target burst units against high-HP elites, while supports keep Ultimates cycling . Himeko-style clear units hold up well in the matching environment.
Honkai: Star Rail 4.5 Stellar Jade Planning
Handling a five-week patch
With two banner halves and overlapping events in a shorter cycle, spend Stellar Jade by filling missing roles first and copies second. Use the free acquisition routes for collaboration units before committing to banners.
Priority table
| Priority | Target | Reason |
|---|---|---|
| Highest | The damage Path you are missing | Two-wave content needs an AoE or role-appropriate carry |
| High | Light Cone and relic stats on your carry | The Path mechanic only runs with a working stat base |
| Medium | Support Energy and Ultimate cycling | Broken cycles shrink your carry's damage window |
| Medium | Collab unit to level 80 | 70% of materials plus 1.6 million Credits covers it |
| Low | Eidolons | Below farming usable relic substats |
Honkai: Star Rail 4.5 FAQ
Q: How are the 4.5 banners split?
A: Robin (Remembrance, Wind) in the first half and Aventurine (Elation, Quantum) in the second, in a version that launched August 26 and runs five weeks .
Q: Is Himeko a 4.5 unit?
A: No. Her SP form launched in 4.4 as a Fire Erudition unit whose core is summoning the mech Trailblazer-Chaser and restoring assist uses.
Q: How many materials does Rin Tohsaka need for level 80?
A: Prepare 70% of her ascension materials plus 1.6 million Credits; materials split into universal, element/role and limited special categories.
Q: Why does Memory of Chaos keep timing out?
A: All floors use a single-position, two-wave structure, so damage must carry between waves. Match your carries to the current Memory Turbulence buff.
Q: What if I am short on Jades in a five-week patch?
A: Fill missing roles first, use free collaboration routes, then decide on banners; skip Eidolon chasing in compressed patches.
