Which Honkai: Star Rail warp gets your Stellar Jade before September 12?

Honkai: Star Rail is HoYoverse's free-to-play turn-based RPG, the one where you ride a space train between planets and acquire characters and gear through a gacha system called Warp. On August 25, 2026 the official account published the banner lineup for the first half of Version 4.5, and as of September 3, 2026 that lineup is still live. It closes on September 12 at 11:59 server time, roughly nine days out.[1]

Two featured banners, one counter

The first half runs two Character Event Warps at the same time. "Summer Chorus" boosts the drop rate of the limited five-star Robin • Summeretto, who walks the Path of Remembrance with Wind as her combat type. "A Rainbow onto Twilight" boosts the limited five-star Hyacine, also Remembrance and also Wind. The four-star rate-ups are identical on both: Dan Heng (The Hunt, Wind), Qingque (Erudition, Quantum) and Gallagher (Abundance, Fire).[1]

The part that trips people up sits here. The two character banners share one guaranteed-drop counter for five-stars. That counter is the mechanism promising a five-star once you hit a set number of pulls, and progress on one banner carries straight over to the other, so pulls spent chasing Hyacine still count toward Robin • Summeretto. The featured-character guarantee, though, resolves per banner.[1]

Light Cones, the equipment characters carry, get two banners of their own. "Brilliant Fixation: Rise and Sing" carries the limited five-star Light Cone Rise and Sing (Remembrance); "Bygone Reminiscence: Long May Rainbows Adorn the Sky" carries Long May Rainbows Adorn the Sky (Remembrance). Both share the same four-star pool of Dream's Montage (Abundance), Geniuses' Greetings (Remembrance) and A Little Getaway (Elation). The two Light Cone banners share a counter with each other, and that counter is unrelated to the character one.[1]

Nothing here rolls into the standard warp

Limited characters and limited Light Cones are not added to Stellar Warp, the permanent banner. Robin • Summeretto comes only from "Summer Chorus," Hyacine only from "A Rainbow onto Twilight," and each Light Cone only from its own banner.[1]

Robin • Summeretto is a debut. HoYoverse ran a separate discussion event for her release on HoYoLAB on August 26.[3] Hyacine is not described as a debut anywhere in the notice, and whether she is a rerun is not something the notice settles.

Celestial Invitation runs alongside. It lets you nominate seven characters on the Character Event Warp in advance. The first five-star you pull there has a 50% chance of being the featured character; when that 50% misses and your nominated list includes the featured character, the featured character sits at 25% and each remaining nominee at 12.5%.[1]

600 Stellar Jade on two different clocks

The Version 4.5 update notice, for the version titled "To Roll the Stars in Astropolis," splits its Stellar Jade into two payments: 300 as maintenance compensation and 300 as bug-fix compensation. Both go to accounts at Trailblaze Level 4 or higher as of the update start, 2026/08/26 06:00 (UTC+8).[2]

The deadlines differ. Maintenance compensation can be claimed any time before Version 4.5 ends at 2026/09/28 06:00 (UTC+8). Bug-fix compensation has to be pulled from in-game mail before 2026/09/25 23:59 (UTC+8), which means logging in.[2] Stellar Jade is the currency Warp consumes; you either earn it in play or buy it.

What else stops at 11:59 on September 12

The banners are not the only thing closing. Aptitude Showcase, the character trial event, ends at the same moment. Any account that has unlocked Travel Log can take Robin • Summeretto, Hyacine, Dan Heng, Qingque and Gallagher through stages on loan, and finishing the challenges pays out Stellar Jades, Adventure Logs, Universal Enhancement Materials and credits.[1] That is the place to find out whether either five-star suits your team before spending anything.

Version 4.5 itself runs until 2026/09/28 06:00 (UTC+8).[2] What opens on September 12 when the first phase closes is not stated in this notice.

The mailbox is the first thing to check. The 300 bug-fix Stellar Jade expires on September 25 at 23:59, and the banners shut well before that.
