HSR 4.5 New Characters and Signature Light Cones

The main new characters expected for HSR 4.5 Banners are Robin Summeretto and Aventurine Waveflair. Both are SP versions of existing characters, but their leaked combat roles are different from their original forms.

Robin Summeretto is listed as Wind and Remembrance. Current leaks suggest her signature Light Cone may be Rise and Sing, with a support-oriented direction. Early information suggests it may provide effects related to Max HP, action flow, Skill Point recovery, and team Speed support.

Aventurine Waveflair is listed as Quantum and Elation. Current leaks suggest his signature Light Cone may be Summer Rides the Surf, with an offensive direction. Early information suggests it may provide effects related to CRIT Rate, Speed, Elation damage, and Skill Point recovery.

These Light Cone names and effects are still leak-based. Players should wait for final numbers before deciding whether to pull only the character or also invest in the signature Light Cone.

Robin Summeretto Banner Overview

Robin Summeretto should not be treated as a simple summer skin. Her original version is a Physical Harmony support, while the leaked HSR 4.5 Banner SP version changes her into a Wind Remembrance character. Her new gameplay direction appears to focus on Remembrance mechanics, summon-based combat, and team support.

Current beta information suggests that Robin Summeretto’s kit revolves around the Vibes resource and the Summer Songbirds mechanic. Her gameplay appears to focus on building team momentum through summons, buffs, and action support.

Robin Summeretto Expected Role

Robin Summeretto is currently expected to work as a Wind Remembrance support built around Vibes, Summer Songbirds, and teamwide damage windows.

Current leaked information suggests that Robin gains Vibes when allies attack, heal, or provide shields. Once all Summer Songbirds are active, she may enter Fever and create a Zone that improves the team’s damage window. If the leaked DEF ignore effect remains, she could become a strong Remembrance support option.

Robin Summeretto Team Compatibility

Robin Summeretto looks most attractive for accounts that already have a Remembrance DPS or a summon-based team core. Early team ideas often pair her with Castorice as the main DPS, Evernight as a sub-DPS or buffer, and Hyacine as the sustain.

This team direction makes sense because Remembrance teams often care about summons, extra actions, HP movement, and teamwide cycling. Robin Summeretto’s leaked Vibes and Songbird mechanics seem designed to make that loop faster and more rewarding.

Players who already own Castorice should pay close attention to Robin Summeretto. If your current team has damage but lacks a true premium buffer, Robin may be the 4.5 character that improves the team most directly.

Aventurine Waveflair Banner Overview

Aventurine Waveflair also changes role heavily. Original Aventurine is an Imaginary Preservation sustain, but Waveflair is leaked as a Quantum Elation damage character. Players should not expect him to replace original Aventurine as a shielder.

Current beta information describes Aventurine Waveflair as an offensive unit built around Elation damage, Fervor, Punchline, and repeated attacks. His Skill and Ultimate deal AoE Quantum damage while building resources. Once enough Fervor is reached, he can trigger stronger Elation attacks.

His leaked kit also rewards frequent team attacks. After teammates attack, he may gain Fervor and Punchline, making him a natural fit for follow-up attack or fast-action teams. Speed may also be an important stat, with early information suggesting that his damage can scale with Speed and CRIT DMG bonuses

Aventurine Waveflair Expected Role

Aventurine Waveflair is currently expected to work as a Quantum Elation DPS built around Punchline, Fervor, repeated attacks, and Speed value.

Current leaked information suggests that his Skill and Ultimate deal Quantum AoE damage while helping him build Punchline and Fervor. His enhanced Elation attacks may create repeated hits or extra follow-up pressure, so he should be treated as an offensive unit rather than a sustain replacement for original Aventurine.

Aventurine Waveflair Team Compatibility

The most common early team idea is Feixiao, Aventurine Waveflair, Topaz, and a sustain unit.

• Feixiao benefits from frequent ally actions.
• Topaz supports follow-up attack damage.
• Aventurine Waveflair adds more repeated hits to the rotation.
• A sustain unit is still needed because Waveflair is not expected to replace original Aventurine’s defensive role.

This team direction is exciting, but it is also more demanding than it looks. If your account already has a strong follow-up attack core, Aventurine Waveflair may be a good damage upgrade. Players without Feixiao, Topaz, or another frequent-attack foundation should wait for final testing before treating him as a must-pull.

Signature Light Cones For Aventurine Waveflair & Robin Summeretto

Robin Summeretto’s expected signature Light Cone is Rise and Sing. Early leak information suggests it may increase the wearer’s Max HP, recover 1 Skill Point for allies after the wearer uses Ultimate, advance the wearer’s action at battle start, and provide teamwide Speed support through its New Melody effect.

Aventurine Waveflair’s expected signature Light Cone is Summer Rides the Surf. Current beta information lists it as an Elation Light Cone that increases CRIT Rate. After using an Elation Skill, the wearer may gain Speed. The Light Cone may also increase Elation value and recover 1 Skill Point after certain wave or repeated Elation Skill conditions.

These Light Cones appear to match the expected mechanics of both SP characters. Robin’s Light Cone is more focused on Remembrance team support, while Aventurine Waveflair’s is designed around Elation damage and offensive stats. Since all effects are still based on leaks, players should wait for final numbers before deciding whether to pull the character only or also invest in the Light Cone.

HSR 4.5 Rerun Banners

Current rerun information is still based on leaks and may change before the official Version 4.5 Special Program or banner notice.

Ashveil Rerun

Ashveil is a 5-Star Lightning Hunt character in Honkai: Star Rail, with a kit focused on follow-up attacks, the Bait mechanic, and Gluttony stacks.

As a Lightning Hunt unit, he is more relevant for players who need single-target pressure, follow-up attack damage, or another Lightning DPS option for boss fights.

Current HSR 4.5 leak discussion lists Ashveil as a possible rerun candidate, but his banner phase and final rerun position have not been officially confirmed. Players who are saving for Ashveil should keep enough Stellar Jade for the official Version 4.5 banner announcement instead of spending everything on other banners first.

Aglaea Rerun

Aglaea is a 5-Star Lightning Remembrance main DPS whose damage revolves around her memosprite Garmentmaker and high-speed combat rhythm.

She is mainly valuable for players who skipped her before, need a Remembrance damage dealer, or want a Lightning DPS built around frequent actions and summon-style mechanics.

Current HSR 4.5 leaks also mention Aglaea as a possible rerun, but HoYoverse has not confirmed her banner slot yet. Players who already have enough Lightning damage coverage can keep Aglaea on the rerun watch list without changing their pull plan immediately.

Robin Summeretto vs Aventurine Waveflair: Which One Should You Pull?

Both HSR 4.5 Banner characters look interesting, but they are not aimed at the same type of account. Robin Summeretto appears to be a team support or buffer for Remembrance-style setups, while Aventurine Waveflair looks more like an offensive unit for follow-up or fast attack teams.

Pull Robin Summeretto If

Robin Summeretto is the better target if you already play Remembrance teams or own characters like Castorice. She is also worth watching if your account already has enough damage dealers but lacks a premium support who can raise the ceiling of an existing team.

She may be especially valuable for players who want stronger teamwide scaling, better burst windows, and more support for summon-related mechanics. If her leaked DEF ignore and action support survive into the final version, her value could be very high for the right roster.

Pull Aventurine Waveflair If

Aventurine Waveflair is the better target if you already enjoy follow-up attack teams or fast offensive teams. Players with Feixiao, Topaz, or other frequent-attack pieces may get more value from him than players starting from an empty roster.

The main warning is that he should not be pulled as a replacement for original Aventurine. If you need a sustain, original Aventurine still fills a very different role. Waveflair looks more like a damage investment, so his team needs another character to keep everyone alive.

Save Your Stellar Jade If

Saving may be the best option if your account is still missing a complete first or second team. A new SP character can look exciting, but a half-built team often performs worse than an older team with proper support, relics, Light Cones, and sustain.

You should also be careful if Version 4.4 already drained your pull budget. The Fate collaboration, Himeko Nova, Rin, and Gilgamesh made 4.4 very expensive for many players. If you are low on Stellar Jade, pick one HSR 4.5 Banner target at most unless both characters clearly fit your account.

How Much Stellar Jade Do You Need for HSR 4.5 Banner?

HSR 4.5 Banner may be expensive if you want both SP characters or their signature Light Cones. A limited 5-star character can take up to 180 pulls in the worst case, while a limited Light Cone can take up to 160 pulls. Check the Pulling advice for HSR 4.4, and see how to make your plan for HSR 4.5 Banner.

That means the rough maximum cost is:

• One limited 5-star character: up to 180 pulls, or 28,800 Stellar Jade
• One limited Light Cone: up to 160 pulls, or 25,600 Stellar Jade
• One character plus signature Light Cone: up to 340 pulls, or 54,400 Stellar Jade
• Both new characters at E0: up to 360 pulls, or 57,600 Stellar Jade

Most players will not always hit the worst-case number, but planning with the worst case prevents bad pull decisions. If you are F2P or a low spender, choosing one main target is safer than trying to chase both characters and both Light Cones.

How To Prepare for HSR Version 4.5 Banners

Version 4.5 is a planning patch. The worst mistake is pulling only because both characters look new. Before the banners arrive, check your pity, guarantee status, saved Special Passes, and expected Stellar Jade income.

Check Your Current Teams

A new character is not always the biggest upgrade. If your current team is missing sustain, action support, or a core damage dealer, pulling the wrong SP character may not solve the problem. If you are still not so clear about your current teams for HSR 4.4, check your current team before next HSR 4.5 banners for best plan.

Robin Summeretto looks better for accounts that already have a Remembrance direction. Aventurine Waveflair looks better for accounts that already have a follow-up or frequent-attack foundation.

Save for One Main Target

F2P and low-spending players should usually choose one target instead of chasing both. Robin Summeretto and Aventurine Waveflair may both be strong, but they help different teams.

If you are unsure, wait for final kit numbers and early testing. A character can look amazing in leaks but become more niche after release, especially if their best team requires several premium units.

Plan Your Stellar Jade Gap

Once the official HSR 4.5 banners details are confirmed, write down your pity, guarantee, tickets, and expected Stellar Jade income before deciding. Whenever there's a lack on your Stellar Jade, never wait to check Honkai Star Rail Top Up by U7BUY for those GREAT DISCOUNT of HSR.

This should be the last step, not the first one. Free Stellar Jade, events, dailies, and pass rewards should always be checked before spending.
