Honkai Star Rail 4.5 Banners: Full Schedule & Pull Guide

Honkai Star Rail‘s Version 4.5 launches August 25, 2026 for NA (August 26 for Asia and Europe), splitting into two banner phases: Robin – Summeretto headlines phase one, Aventurine – Waveflair headlines phase two, and the whole patch runs just five weeks instead of the usual six. That missing week matters more than it sounds, because it shrinks how much Stellar Jade you accumulate before the version closes. This guide covers who’s in each phase, what the shortened calendar actually costs a saving player, and what to finish before the patch rolls over.

Robin – Summeretto and Aventurine – Waveflair are the featured characters in Honkai: Star Rail 4.5, and both are reworked forms of characters who already exist in the roster rather than new additions to the cast. Robin – Summeretto shifts from the original Robin’s Harmony support role to the Remembrance Path, coming in as a Wind unit built around a different kind of team utility than her base version. On the other side, Aventurine – Waveflair shifts from the original Aventurine’s Preservation sustain role to Quantum Elation, moving him from a defensive anchor into a damage-focused offensive slot. If you already own either base character, this is effectively a second, separately-pulled unit sharing their name and lore, similar to how Dan Heng and his Imbibitor Lunae form work as two distinct pulls.

Note that final numbers on both new kits weren’t locked in official channels at the time of writing, so treat exact multipliers and buff values as subject to last-minute adjustment until the in-game banner page goes live.

Robin – Summeretto’s banner, Summer Chorus, will be available from August 25, 2026 (UTC-5) until September 12, 2026, running alongside Hyacine’s rerun with the same rate-up 4-star characters, Dan Heng, Qingque, and Gallagher. Phase two flips the lineup: Aventurine – Waveflair’s banner will be available from September 12, 2026 until September 27, 2026 (UTC-5), paired with Ashveil’s first rerun in Phase 2, with rate-up 4-stars Sampo, Hook, and Guinaifen.

A standard Honkai Star Rail version lasts six weeks and gives players a predictable rhythm of jade from daily missions, main story and exploration rewards, weekly endgame clears, and events. Version 4.5 will last for 5 weeks instead of the usual 6-week schedule, which means one full week of that rhythm simply doesn’t happen this time. Daily missions still hand out their usual Stellar Jade every day, but you lose an entire week of exploration rewards on the new Astropolis content, one weekly reset of endgame mode clears, and whatever mid-patch livestream code drop would normally land in that missing week. None of that is a huge single number on its own, but stacked together it’s the difference between comfortably banking for one banner and stretching to cover two.

Weekly modes like Simulated Universe and its related endgame content are worth clearing every reset regardless of which banner you’re saving for, since that jade counts toward either target. If you’re still figuring out where your Trailblaze Power should go during a shorter patch, prioritizing story and exploration nodes over side content gets you more jade per stamina point spent right now.

Here’s the number that actually matters when you’re deciding whether to save for one banner or gamble on both. A single warp costs 160 Stellar Jade, and daily training missions hand out 60 Stellar Jade per day. That means daily missions alone fund roughly one pull every 2.7 days — meaning across a full five-week patch, dailies by themselves cover something in the neighborhood of a dozen pulls, well short of the 90 needed to guarantee a hard-pity 5-star. Everything else — story rewards, exploration, endgame clears, event jade — has to fill the rest of the gap, and with a week trimmed off this patch, there’s less of that filler than usual.

Once a phase ends, its banner closes and any rate-up character or light cone drops out of the featured pool until a future rerun, which is never guaranteed on any fixed timeline. The same applies to limited events tied to the patch’s Astropolis setting: their reward tracks and any one-time cosmetic or material rewards typically vanish for good once the version rolls into 4.6. Exact event names and their reward lists weren’t fully public at the time of writing, so check the in-game Events tab as soon as 4.5 lands rather than assuming a reward will still be around in a later patch.

Myth: Robin Summeretto and Aventurine Waveflair Are New Characters

They’re new playable forms of characters already in the game, with a different Path and element than their base versions, not additions to the overall cast. If you’re newer to the game and unclear on how paths, elements, and character identity interact, the new player guide covers that groundwork without repeating it here.

Myth: The Phase Split Means You Have to Choose One and Forget the Other

Nothing stops you from pulling in both phases if you’ve got the jade for it — the phases just determine when each character is available, not whether you’re allowed to pull for both. The real constraint is your jade income, not any in-game rule locking you out of one banner because you pulled on the other.

Myth: A Shorter Patch Means Rewards Scale Down to Match

Daily and weekly reward rates don’t change because a patch is shorter — you just get fewer total days and resets to collect them in. The shrink hits your total accumulation, not the per-day rate, which is exactly why the five-week window changes the math for anyone trying to save for two banners at once.
