Honkai: Star Rail 4.5 Release Date and Banners

Honkai: Star Rail Version 4.5 is shaping up to be the game's summer SP-character patch. HoYoverse has already revealed Robin - Summeretto and Aventurine - Waveflair through the official "Variations on a Cosmic Tour" teaser campaign, but the full Version 4.5 Special Program has not aired yet as of August 6, 2026.

That means the safest answer is this: Honkai: Star Rail 4.5 is expected to release on August 26, 2026 for Europe and Asia, with North America likely seeing the update on August 25 because of time zones. The headline banners are expected to feature Robin - Summeretto and Aventurine - Waveflair, while rerun banners, four-star rate-ups, and final Light Cone details are still waiting for official confirmation.

Honkai: Star Rail 4.5 Release Date

Version 4.5 is expected to go live on Wednesday, August 26, 2026, following the usual six-week update cycle after Version 4.4. For North America, the displayed date may be Tuesday, August 25, 2026, because Honkai: Star Rail version updates launch globally at the same moment but appear differently across time zones.

This date is very likely if the game keeps its standard update rhythm, but players should still treat it as an estimate until HoYoverse publishes the official maintenance notice. The Version 4.5 livestream is expected before the patch and should lock in the banner order, event list, redemption codes, Light Cones, and any reruns.

HSR 4.5 Banner Schedule

The two new 5-star characters expected for Version 4.5 are Robin - Summeretto and Aventurine - Waveflair. Both are SP-style versions of existing characters, not simple paid outfits. Their Elements and Paths are different from their original forms, so players should plan around their new combat roles instead of assuming they play like the Robin and Aventurine already in the game.

The most important caveat is reruns. Current pre-release discussion points to possible reruns such as Ashveil and Aglaea, but rerun banners are not locked until HoYoverse confirms them. If you are saving for a rerun, keep enough Stellar Jade flexible until the official Special Program.

Robin - Summeretto Banner

Robin - Summeretto is expected to headline the first half of Version 4.5. HoYoverse's teaser identifies her as a summer-themed form of Robin, while current banner coverage lists her as a 5-star Wind character on the Path of Remembrance.

That is a major shift from the original Robin, who is a Physical Harmony support. Summeretto should not be treated as a skin or a small variation. If the current beta and leak discussion stays close to launch, she is more likely to act as a Remembrance support or enabler built around team momentum, summons, and damage-window setup.

Expected Role

Robin - Summeretto looks most interesting for accounts that already have a Remembrance core. If you use characters such as Castorice, Evernight, or other summon-driven units, Summeretto may become one of the most valuable upgrades of Version 4.5. The early discussion around her kit focuses on teamwide support rather than a simple personal DPS role, so her real value will depend heavily on how much your account can take advantage of Remembrance mechanics.

Pull Robin - Summeretto If:

· You already play Remembrance or summon-based teams.

· You own a strong Remembrance DPS and want a dedicated premium support.

· You prefer long-term team upgrades over another standalone damage dealer.

· You like Robin and want a new version with a different combat identity.

· You are willing to wait for final numbers before committing to her Light Cone.

Consider Skipping Robin - Summeretto If:

· Your account still lacks a reliable main DPS.

· You do not have a Remembrance team foundation.

· You already have enough supports but lack sustain or damage coverage.

· You only want her because she is summer-themed and have no team ready for her.

Aventurine - Waveflair Banner

Aventurine - Waveflair is expected to arrive in the second half of Version 4.5. This version of Aventurine is currently listed as a 5-star Quantum character on the Path of Elation, which is a huge role change from the original Imaginary Preservation Aventurine.

The key planning point is simple: Waveflair is not expected to replace original Aventurine as a shielder. If you pull him, you should expect an offensive character, likely built around repeated attacks, Elation damage, and follow-up pressure. Teams using him may still need a separate healer or shielder.

Expected Role

Waveflair may be especially attractive for players who already run follow-up attack teams and want another source of repeated damage. Early team ideas often mention characters such as Feixiao and Topaz, but the final best teams will depend on official numbers, speed breakpoints, and whether his strongest setup wants another Elation unit or a more traditional follow-up shell.

Pull Aventurine - Waveflair If:

· You want a Quantum offensive unit rather than another sustain.

· You already have follow-up attack pieces built.

· You like fast teams that trigger frequent extra attacks.

· You can provide a separate healer or shielder.

· You are an Aventurine fan and want his new summer SP form.

Consider Skipping Aventurine - Waveflair If:

· You need a defensive Aventurine-style shield unit.

· Your follow-up attack roster is incomplete.

· You are short on Stellar Jade after Version 4.4.

· You already have several strong damage dealers but lack supports or sustain.

Expected Light Cone Banners

Each new 5-star character should receive a matching limited Light Cone banner. Current leak discussion points to Rise and Sing for Robin - Summeretto and Summer Rides the Surf for Aventurine - Waveflair, but those names and effects are not officially final at the time of writing.

For most players, the character should come before the Light Cone. A new limited unit changes an account more than a signature weapon, especially when the patch information is still pre-release. If you are free-to-play or a low spender, wait for final kit testing before deciding whether either signature is worth the extra pulls.

HSR 4.5 Rerun Banners

The 4.5 rerun lineup is the least certain part of the patch. Some pre-release sources mention Ashveil and Aglaea as possible rerun candidates, but this should be treated as leak-based until the Special Program confirms the final banners.

If Ashveil reruns, he would interest players who want Lightning single-target pressure and follow-up attack value. If Aglaea reruns, she may matter more for players building around Remembrance or summon-related teams. However, reruns can change before official announcement, so do not spend your 4.4 savings assuming these names are guaranteed.

Should You Pull Robin or Aventurine in HSR 4.5?

For most accounts, the choice depends less on raw strength and more on team structure.

Robin - Summeretto is the cleaner pick if your account already has a Remembrance DPS and needs a stronger enabler. Aventurine - Waveflair is the more exciting pick if your account is built around frequent attacks and follow-up damage. If you are missing both the team foundation and the Stellar Jade, skipping 4.5 is completely reasonable.

How Much Stellar Jade Do You Need?

Honkai: Star Rail's limited character banner uses 160 Stellar Jade per pull. A 5-star can take up to 90 pulls, and guaranteeing the featured 5-star from zero pity can require up to 180 pulls if you lose the first 50/50.

Actual costs are often lower because of soft pity, existing pity, and saved guarantees. Before Version 4.5 starts, check your current pity, whether your next 5-star is guaranteed, and how many pulls you can earn from Version 4.4's remaining events.

Pull Planning Before Version 4.5

The end of Version 4.4 is awkward because players are still deciding between Himeko - Nova, Fate collaboration banners, and reruns like Aventurine, Cerydra, and Anaxa. If you want Robin - Summeretto or Aventurine - Waveflair, the safest plan is to stop pulling once you no longer have enough for your 4.5 target.

A practical saving rule:

· If you are on a guarantee, keep at least 90 pulls for your main 4.5 target.

· If you are not on a guarantee, keep up to 180 pulls if you want to be safe.

· If you also want a signature Light Cone, wait for official kit reviews before spending.

· If reruns are important to you, keep extra Jade until the livestream confirms them.

Conclusion

Honkai: Star Rail 4.5 is expected to be a summer-themed banner update centered on Robin - Summeretto and Aventurine - Waveflair. Robin looks like the better early target for Remembrance and summon-team players, while Aventurine looks more appealing for accounts with follow-up attack or fast-action cores.

Because the full Version 4.5 livestream and maintenance notice are still pending, the best approach is to treat the date as highly likely but not fully official, treat reruns as uncertain, and save enough Stellar Jade for one clear target before chasing Light Cones or extra banners.
