Both are new five-star forms rather than simple reruns. The first is a Wind Remembrance support built around the Summer Songbirds and a teamwide Fever Zone. The second is a Quantum character on The Elation Path who acts as an AoE carry and converts Punchline and Fervor into large multi-hit attacks. Their signature Light Cones are also known, giving players a clearer view of the patch’s overall pull value.
Version 4.5 Banner Schedule Overview

The Version 4.5 release date is currently estimated for late August 2026. Using the projected 21-day banner phase format, Phase 1 may begin around August 25, 2026, while Phase 2 may start around September 16, 2026.
These dates are estimates rather than an official schedule. The exact start time, four-star rate-up characters, rerun lineup, and banner names remain subject to change.
| Banner Phase | Estimated Dates | Featured 5-Star Character | Element | Path | Featured Light Cone |
|---|---|---|---|---|---|
| Phase 1 | Aug. 25 – Sept. 16, 2026 | Robin • Summeretto | Wind | Remembrance | Rise and Sing |
| Phase 2 | Sept. 16 – Oct. 6, 2026 | Aventurine • Waveflair | Quantum | The Elation | Summer Rides the Surf |
This patch offers two very different account upgrades. Phase 1 focuses on team tempo, Energy, DEF ignore, and an extended burst window. Phase 2 is built around fast ally attacks, shared resource generation, and repeated AoE Elation damage. That makes the better banner dependent on whether an account needs a flexible amplifier or a new damage dealer.
Which New Characters Are Debuting in Version 4.5?
Phase 1: Robin • Summeretto
Robin • Summeretto is a five-star Wind character on the Path of Remembrance. She is an HP-scaling support and Sub-DPS who summons three Summer Songbirds and builds a unique resource called Vibes.
Her rotation begins by summoning Bessie. As allies attack, heal, and provide Shields, more Vibes are generated and the other birds join the field. Once the full trio is present, she enters Fever and creates a Zone that allows allied attacks to ignore enemy DEF. At the normal E0 cap, that effect can reach up to 40% DEF ignore while her Vibe count is at its highest.
Her Ultimate also advances one ally by 100%, restores Energy equal to 20% of that unit’s Max Energy, and marks them as the Special Guest. This gives an active main carry another turn while helping the team build Vibes faster. The birds then contribute their own AoE Wind damage during the performance.
For the meta, this is a high-value support kit with action advance, Energy recovery, DEF ignore, damage amplification, Crowd Control protection, and off-turn damage. She should be strongest beside a carry who attacks often and can place several important actions inside one Fever window.
Phase 2: Aventurine • Waveflair
Aventurine • Waveflair is a five-star Quantum character on The Elation Path. Unlike the original Preservation version, this form is an AoE carry rather than a sustain unit.
His kit revolves around Punchline and Fervor. Whenever a teammate attacks, he gains more of both resources. Reaching the required Fervor threshold prepares an enhanced Elation attack for the next Aha Instant, turning the whole party’s activity into fuel for his burst.
The standard Elation Skill deals an AoE hit followed by ten random single-target hits. Its enhanced version, All in! To the Blazing Summer, consumes stored Fervor and adds one more random hit for every point spent. Against a boss, many of those hits can land on the same target; against a wave, they spread across the field.
His first major build target is 160 SPD. Reaching it activates Party of Euphoria for 30% Elation, and every additional SPD point adds more Elation. He therefore prefers fast teammates, Follow-Up ATKs, extra attacks, and enemy-side debuffs such as DEF reduction, RES reduction, RES PEN, or increased damage taken.
One important warning is that normal DMG Boost effects do not improve his special Elation damage. Players should not judge his best supports in the same way they would evaluate a standard Quantum DPS.
What New Weapons Are Releasing in Version 4.5?
Rise and Sing (Robin • Summeretto’s Signature Light Cone)
Rise and Sing is the recommended signature Light Cone for the Phase 1 character. At Superimposition 1, it increases the wearer’s Max HP by 30%, advances their action by 40% when entering combat, and restores one Skill Point after they use their Ultimate.
It also grants New Melody for two turns at the start of battle. While this effect is active, all allies gain 20% SPD. The HP bonus improves her personal damage, the Summer Songbirds’ durability and output, and the HP-based ATK buff from her Bonus Ability.
This Light Cone has strong pull value because it improves both setup speed and team economy. However, it is not the only usable option. Players with a limited Stellar Jade budget can still use alternatives such as To Evernight’s Stars or Memory’s Curtain Never Falls.
Summer Rides the Surf (Aventurine • Waveflair’s Signature Light Cone)
Summer Rides the Surf is the best-in-slot Light Cone for the Phase 2 carry. At Level 80, it provides 953 HP, 582 ATK, and 529 DEF. Its passive also grants 18% CRIT Rate.
After the wearer uses an Elation Skill, the Light Cone grants Hype, increasing SPD by 20%. If the Elation Skill is different from the previous one, it also grants Trend and increases Elation by 36%. His normal rotation moves between the standard and enhanced attacks, so he can activate this condition naturally.
The weapon also restores one Skill Point at the start of each wave or after three Elation Skill uses. It directly supports the 160 SPD breakpoint, improves CRIT consistency, and makes a Skill-heavy team easier to run. Even so, Today’s Good Luck and A Little Getaway remain usable lower-cost alternatives.
Players who are short on Stellar Jades or Oneiric Shards should prioritize the character before the signature Light Cone unless their account already has a complete team for that unit.
Which Characters Are Rerunning in Version 4.5?
The rerun characters for Version 4.5 are currently unknown.
No confirmed rerun lineup was included in the supplied information. We therefore do not yet know which returning five-star characters or Light Cones will share Phase 1 and Phase 2 with the two new units.
This part should be updated once the official Warp details are announced. Until then, players should avoid spending Stellar Jades from current codes and events based only on rerun rumors.
Are the Version 4.5 Characters Worth Pulling?
Robin • Summeretto: Pull for active hypercarry and Remembrance teams. She currently looks like the safer general account investment. Teamwide DEF ignore, full action advance, Energy restoration, damage amplification, and Crowd Control protection are all effects that can remain useful across several damage dealers. Her main limitation is setup: the team must build Vibes and place its strongest attacks near the start of Fever.
Aventurine • Waveflair: Pull for Elation teams or fast multi-attacker lineups. He offers a much more specialized form of account value. Players who can reach the 160 SPD target and field teammates with frequent attacks, Follow-Up ATKs, or strong enemy debuffs should get far more from him. Players who need a shielder or general sustain should skip this form, because he does not replace the original Preservation Aventurine.
Best F2P priority: Robin • Summeretto has the safer early pull value. A premium support is usually easier to reuse, while the Quantum carry asks for a more specific team and stat setup. However, accounts that already own strong amplifiers and lack an AoE damage dealer may gain more immediate value from Phase 2.
Signature Light Cones: Optional rather than mandatory. Both signatures improve their intended rotations, but the supplied builds include lower-cost alternatives. F2P players should secure the preferred character first, test the available replacement Light Cones, and only continue pulling if enough pity and currency remain.
Rerun Characters: To be updated. The final pull order may change if Version 4.5 includes a top-tier rerun support, sustain, or DPS.
Frequently Asked Questions (FAQ)
When is the Honkai: Star Rail Version 4.5 release date?
The update is currently estimated to launch around August 25, 2026. Phase 2 may begin around September 16, 2026. These dates are projections and should be replaced once the official schedule is announced.
Who are the new five-star characters in the Version 4.5 banner phases?
Phase 1 is expected to feature Robin • Summeretto, a Wind Remembrance support who uses Vibes, Summer Songbirds, and a Fever Zone. Phase 2 is expected to feature Aventurine • Waveflair, a Quantum character on The Elation Path who serves as an AoE carry.
Should F2P players pull Robin • Summeretto or Aventurine • Waveflair?
Robin • Summeretto is the safer general recommendation because her action advance, Energy support, DEF ignore, and damage amplification can help several carries. Choose Aventurine • Waveflair instead when the account already has strong supports and can build a fast team that attacks often.
What are the Version 4.5 signature Light Cones?
The supplied information lists Rise and Sing for Robin • Summeretto and Summer Rides the Surf for Aventurine • Waveflair. The first focuses on HP, opening tempo, team SPD, and Skill Point recovery. The second provides CRIT Rate, SPD, Elation, and additional Skill Point support.
