Aventurine trades his usual boardroom composure for a beach chair with Aventurine • Waveflair, a summer variant of the Ten Stonehearts member who arrives with a new path, a new element, and a fresh outfit. His debut lines up with a trip toward Astropolis near the IPC’s headquarters, where a festival on the coast hides a brewing storm.
Quick answer: Aventurine • Waveflair is expected in the second half of Honkai Star Rail Version 4.5, with the estimated banner running from September 16, 2026 (UTC-5) to October 6, 2026 (server time). No exact launch time has been officially confirmed yet.
Release status and estimated window
Status: Window (estimated). Aventurine • Waveflair was teased through official drip marketing on Honkai Star Rail’s social channels and is set to release during Version 4.5. He is expected to appear in Phase 2 of that patch, following the release of Himeko • Nova earlier in the cycle.
If Version 4.4 keeps the standard six-week patch length, the second half of 4.5 lands in mid-September. That places his estimated banner from September 16, 2026 (UTC-5) through October 6, 2026 (server time). These dates follow the game’s usual schedule and are not a confirmed launch time, so treat them as a planning window rather than a fixed date.

Path, element, and rarity
Aventurine • Waveflair is a 5-star character who walks the path of the Elation and deals Quantum damage. That is a notable shift from the original Aventurine, who follows Preservation and fills a sustaining role. This summer form steps into an offensive Elation role instead.
| Profile | Value |
|---|---|
| Rarity | 5-Star |
| Path | The Elation |
| Element | Quantum |
| Species | Avgin |

Who is Aventurine • Waveflair
This is Aventurine’s day off. His character introduction explains that a promotion to P46 finally lets him step away from work and take a vacation near the IPC’s headquarters. The move to the Elation path fits the tone, showing a version of the character who has loosened the strict discipline of Preservation to enjoy the beach.
The setup is not entirely relaxing, though. The story frames a festival lighting up the shore while a storm builds within the Euphoria. Carrying secret orders, he returns to the center of the trouble to shake up the holiday and, in his own words, turn the tides.
Aventurine • Waveflair voice actors
The full voice cast carries over from the original Aventurine, so fans of the character keep the same performers across all four languages.
| Language | Voice actor |
|---|---|
| English | Camden Sutkowski |
| Chinese | Yang Chaoran |
| Japanese | Kawanishi Kengo |
| Korean | Park Jun-won |
Yang Chaoran is a familiar voice across HoYoverse titles, having also played Alhaitham in Genshin Impact, Dan Feng in Honkai Star Rail, and Su in Honkai Impact 3rd. Kawanishi Kengo is known for roles such as Muichiro Tokito in Demon Slayer and Shigeru Yahaba in Haikyu!!, while Park Jun-won appears in games including Love and Deepspace and AFK Journey.
Base stats at level 80
At maximum level without ascension boosts, Aventurine • Waveflair posts the following base numbers. His speed of 103 matters because his kit rewards high SPD investment for extra Elation scaling.
| Stat | Level 80 |
|---|---|
| HP | 1,242 |
| ATK | 427 |
| DEF | 752 |
| SPD | 103 |
| CRIT Rate | 5% |
| CRIT DMG | 50% |
| Energy | 140 |
How to prepare before he arrives
Since the exact banner is still an estimate, the safest prep is saving Stellar Jade so you can pull when the banner goes live. Keeping a reserve now avoids a last-minute crunch during Phase 2 of 4.5.
You can top up your Jade for free by redeeming active codes on the official Honkai Star Rail gift redemption page. Codes expire quickly, so redeem them as soon as they appear rather than saving them for later.
Because he pairs well with other Elation characters and benefits from stacking speed, planning around a supporting lineup ahead of time will let you use him effectively the moment he releases. Once the banner opens in-game, you will see his featured 5-star image on the warp screen, which confirms the rate-up is live.
