HSR 4.5 Banner Leaks: Robin Summeretto, Aventurine Waveflair & Order

Honkai: Star Rail Version 4.5 is expected to feature two summer-themed new 5-star forms: Robin Summeretto and Aventurine Waveflair. Current pre-release information points to Robin Summeretto appearing earlier in the version and Aventurine Waveflair appearing later, but reruns, four-star rate-ups and final Light Cone details should still be checked against HoYoverse’s official livestream and in-game notices.

Players who are already saving for Robin Summeretto, Aventurine Waveflair or another 4.5 banner target can compare Oneiric Shard and Express Supply Pass options on the Honkai: Star Rail top-up page at Topuplist. Topuplist lists UID-based HSR top-up for Global servers, but you should calculate your pity, guarantee and expected free pulls before spending.

According to PC Gamer’s current Honkai: Star Rail banner tracker, Robin Summeretto and Aventurine Waveflair are described as brand-new 5-star characters rather than shop outfits. That distinction matters because owning original Robin or original Aventurine does not mean you will automatically own their 4.5 summer forms.

This guide focuses on banner order, release window and pull planning. It does not fully analyze Robin Summeretto’s kit, Aventurine Waveflair’s kit, Eidolons, Light Cones or best teams.

Banner Item	Current Status	What It Means
Robin Summeretto	Expected 4.5 new 5-star form	Summer-themed Robin form, not original Robin’s costume
Aventurine Waveflair	Expected 4.5 new 5-star form	Summer-themed Aventurine form, separate from original Aventurine
Expected release window	Late August 2026	Based on 4.4 ending around August 25 and the usual update cycle
Expected order	Robin first, Aventurine later	Current pre-release expectation, not final in-game banner notice
Rerun lineup	Not confirmed	Wait for official livestream confirmation
Light Cone banners	Not fully confirmed	Treat names and effects as subject to change

The safest reading is simple: Robin Summeretto and Aventurine Waveflair are the two headline 4.5 new forms, while the full banner structure still needs official confirmation.

Is Robin Summeretto Confirmed for HSR 4.5?

Robin Summeretto is being tracked as one of the headline 4.5 characters. The important point is that she should not be treated as a simple skin for original Robin. She is expected to be a separate playable form, which means players who own original Robin still need to pull Robin Summeretto if they want this new version.

Current pre-release coverage describes Robin Summeretto as a different combat form from original Robin. However, this article does not judge her final strength, teams or Light Cone value. Those details should be covered in a separate Robin Summeretto kit guide once the information is more stable.

For banner order, HoYoLAB’s Midsummer preview post lists Robin Summeretto for the upcoming Version 4.5 first phase and Aventurine Waveflair for the second phase. Until the full livestream and in-game notices are available, players should still treat detailed pull priority, rerun partners and Light Cone details as subject to change.

Is Aventurine Waveflair Confirmed for HSR 4.5?

Aventurine Waveflair is also being tracked as a new 4.5 summer-themed 5-star form. This is not the same as original Aventurine’s 4.4 Phase 2 rerun.

That distinction is especially important because original Aventurine is part of the current 4.4 Phase 2 rerun set. Original Aventurine is the existing Preservation sustain, while Aventurine Waveflair is a new 4.5 form with a separate banner decision.

If you are deciding between pulling original Aventurine now and saving for Aventurine Waveflair later, do not treat them as the same unit. Original Aventurine solves a current sustain problem. Aventurine Waveflair should be evaluated as a future 4.5 character once final kit and banner information is clearer.

Version 4.5 is expected around late August 2026. GameSpot’s Honkai: Star Rail update guide estimates that the next update would arrive around August 26 if the game follows its usual six-week update cycle.

That timing matches the current 4.4 Phase 2 window, which runs into late August. Players spending during 4.4 Phase 2 should therefore assume that 4.5 savings time is already limited.

Expected Phase 1

Robin Summeretto is expected to headline the first half of Version 4.5. Players targeting her should be more conservative with 4.4 Phase 2 pulls because an early 4.5 banner leaves less time to recover Stellar Jades.

Expected Phase 2

Aventurine Waveflair is expected later in the version. This may give players slightly more time to save, but it does not make random 4.4 spending safe. If you want Waveflair and are not guaranteed, preserving pity is still the cleaner strategy.

Still Not Confirmed

The following details should not be treated as final yet:

Exact banner dates
Final Phase 1 and Phase 2 structure
Rerun characters
Four-star rate-ups
Signature Light Cone effects
Event rewards
Livestream codes
Final kit values
Maintenance schedule

Expected Phase	Expected New 5-Star	Current Status	What to Watch
Phase 1	Robin Summeretto	Expected / pre-release information	Final Path, kit, Light Cone and rerun partner
Phase 2	Aventurine Waveflair	Expected / pre-release information	Final Path, kit, Light Cone and rerun partner
Reruns	TBA	Not confirmed	Wait for livestream confirmation
Four-stars	TBA	Not confirmed	Usually revealed closer to launch
Light Cones	TBA	Not fully confirmed	Final names and effects may change before release

Do not build a full pull plan around reruns yet. Until the 4.5 livestream, only the two headline new forms are safe to discuss with higher confidence.

How 4.4 Phase 2 Affects Your 4.5 Savings

HSR 4.4 Phase 2 can directly drain your 4.5 resources. The current patch includes Cerydra, Anaxa and original Aventurine in the late-version banner window, which means every pull spent now may reduce your chance to secure Robin Summeretto or Aventurine Waveflair.

If you want Robin Summeretto, be especially careful. If she appears in the first half of 4.5 as expected, you will have less time to rebuild resources after 4.4 Phase 2 ends.

If you want Aventurine Waveflair, you may have slightly more time, but you should still avoid spending a guarantee on optional 4.4 upgrades unless they solve a real account problem.

If you are considering original Aventurine in 4.4 Phase 2, remember that he is not Aventurine Waveflair. Original Aventurine is a rerun sustain. Waveflair is a new 4.5 form.

Should You Pull in 4.4 Phase 2 or Save for 4.5?

Player Situation	Recommendation	Reason
You want Robin Summeretto most	Save now	Expected earlier 4.5 timing leaves less recovery time
You want Aventurine Waveflair most	Lean save	Later expected timing helps, but guarantee still matters
You lack sustain and want original Aventurine	Pull only if survival is blocking you	Original Aventurine solves a different problem from Waveflair
You only want Cerydra or Anaxa	Pull if they fix your current roster	Do not pull just because Phase 2 is live
You are on 50/50 with low savings	Avoid random pulls	Winning or losing can both disrupt 4.5 plans
You want both 4.5 new forms	Save everything	Two limited 5-stars require serious resources

The cleanest rule is:

If your 4.4 Phase 2 pull does not solve an immediate account problem, saving for 4.5 is the better strategy.

What About 4.5 Rerun Leaks?

Rerun information is not stable enough for a final priority list yet.

Community trackers may predict possible reruns, but rerun names are more fragile than the headline new-character information. Do not treat a rerun prediction as a confirmed banner until HoYoverse reveals the official 4.5 preview.

A safe pre-livestream article should say:

Reruns are not confirmed. Wait for the official 4.5 livestream before making a final rerun pull plan.

This page should be updated after:

The 4.5 livestream date is announced
The official livestream airs
Banner art is posted
In-game notices confirm phase order
Light Cone banners are revealed
Patch notes go live

What About Robin and Aventurine Waveflair Light Cones?

Most players should plan around the characters first, not their Light Cones.

Until official information is available, do not make final E0S1, E1 or Light Cone priority decisions. A signature Light Cone can be valuable, but it usually optimizes a character you already own rather than replacing the need to pull the character.

For F2P and low-spending players, the safer rule is:

Secure the character first. Think about the Light Cone only after you know you can afford the character.

This article does not rank 4.5 Light Cones. That should be handled in a separate Light Cone leak or priority guide after the banner details are clearer.

First, decide your main 4.5 target. Choose between Robin Summeretto, Aventurine Waveflair, a possible rerun or saving for 4.6. Do not try to chase every option unless you already have enough resources.

Second, check your pity and guarantee. A player with high pity and guarantee can plan much more aggressively than a player at low pity on 50/50. Character banner pity and Light Cone pity are separate, so spending on a Light Cone does not help your next limited character.

Third, avoid optional upgrades. That includes 4.4 Phase 2 Light Cones, non-essential Eidolons and “just a few pulls” on banners that do not solve your roster problem.

Fourth, recheck after the livestream. This is a pre-livestream planning guide. The article should be updated immediately once HoYoverse confirms the official 4.5 order, reruns, events and Light Cones.

FAQ

Is Robin Summeretto coming in HSR 4.5?

Yes, current pre-release information points to Robin Summeretto as one of the two headline 4.5 summer-themed new forms. She should be treated as a separate banner target from original Robin.

Is Aventurine Waveflair coming in HSR 4.5?

Yes, Aventurine Waveflair is being tracked as the other headline 4.5 new form. He is separate from original Aventurine’s 4.4 Phase 2 rerun.

Current information points to Robin Summeretto first and Aventurine Waveflair later. Final banner structure should still be checked against the official livestream and in-game notices.

When will HSR 4.5 release?

Version 4.5 is expected around late August 2026, with August 26 being the likely update window if the usual six-week cycle holds.

Are Robin Summeretto and Aventurine Waveflair skins?

No. They are being described as new 5-star characters rather than shop outfits, so they should be treated as separate playable banner targets.

Should I pull in 4.4 Phase 2 or save for 4.5?

Save if your 4.4 Phase 2 pull does not solve an immediate roster problem. Pull only if Cerydra, Anaxa or original Aventurine directly fixes your account.

Are 4.5 reruns confirmed?

No. Reruns should be treated as speculative until HoYoverse confirms the official 4.5 banner lineup.

Final Verdict

Honkai: Star Rail 4.5 is expected to feature Robin Summeretto and Aventurine Waveflair as the two headline new summer-themed 5-star forms. Current information points to Robin Summeretto first and Aventurine Waveflair later, but the final order, reruns, four-stars and Light Cone banners still need official confirmation.

Players targeting Robin Summeretto should save aggressively because she is expected earlier. Players targeting Aventurine Waveflair may have slightly more time, but should still avoid unnecessary 4.4 Phase 2 spending.

The best strategy before the 4.5 livestream is simple: save if your current banner pull does not fix a real account problem, and update your plan once the official 4.5 banners are confirmed.
