Robin Summeretto headlines the first half of Honkai: Star Rail Version 4.5 on a limited Event Warp called Summer Chorus. She arrives as a 5-star Wind unit on the Remembrance Path, a full move away from her original Harmony role, and her banner carries the usual set of boosted 4-star characters and Light Cones you can pick up while pulling.
Quick answer: The rate-up 4-star characters are Dan Heng (Wind, The Hunt), Qingque (Quantum, Erudition), and Gallagher (Fire, Abundance). The rate-up 4-star Light Cones are Geniuses’ Greetings (Remembrance), Dream’s Montage (Abundance), and A Little Getaway (Elation).
Summer Chorus banner schedule
Robin Summeretto’s banner opens with the Version 4.5 update and runs for the entire first phase, giving you roughly 21 days to pull her. Her signature Light Cone, Rise and Sing, runs at the same time on the paired Brilliant Fixation warp. Here is when the banner goes live and ends on each server.
| Server | Start | End |
|---|---|---|
| America (UTC-5) | Aug 25, 2026, 10:00 PM | Sep 12, 2026, 11:59 AM |
| Europe (UTC+1) | Aug 26, 2026, 4:00 AM | Sep 12, 2026, 11:59 AM |
| Asia (UTC+8) | Aug 26, 2026, 11:00 AM | Sep 12, 2026, 11:59 AM |
Featured 4-star characters
Three 4-star characters get a boosted drop rate throughout phase one. Any 4-star result on the banner has a higher chance of landing one of these three, which is useful if you want extra Eidolons for any of them.
| Character | Element | Path |
|---|---|---|
| Dan Heng | Wind | The Hunt |
| Qingque | Quantum | Erudition |
| Gallagher | Fire | Abundance |
Alongside them, Robin Summeretto is the featured 5-star, and a Hyacine rerun (Wind, Remembrance) runs during the same phase on her own banner. Both are Wind Remembrance units, so this half of 4.5 leans hard into that archetype.
Featured Light Cones
The 5-star Light Cones for this phase are Rise and Sing, Robin Summeretto’s signature, and Long May Rainbows Adorn the Sky, which is Hyacine’s signature. Both are Remembrance Light Cones and appear on the paired Brilliant Fixation warp. Three 4-star Light Cones also get a boosted drop rate.
| Light Cone | Rarity | Path |
|---|---|---|
| Rise and Sing | 5-star | Remembrance |
| Long May Rainbows Adorn the Sky | 5-star | Remembrance |
| Geniuses’ Greetings | 4-star | Remembrance |
| Dream’s Montage | 4-star | Abundance |
| A Little Getaway | 4-star | Elation |
Warp rates and pity
Summer Chorus uses the standard limited-character warp rates. A 5-star has a base 0.6% pull rate and is guaranteed within 90 warps. When you hit that 5-star, there is a 50% chance it is Robin Summeretto. If you lose that coin flip and get a standard 5-star instead, your next 5-star is guaranteed to be her.
| Rarity | Rate | Pity |
|---|---|---|
| 5-star character | 0.6% | Guaranteed by 90 warps |
| 4-star character or Light Cone | 2.55% each | Guaranteed by 10 warps |
| 3-star Light Cone | 94.3% | — |
Every 10 pulls guarantees at least one 4-star item, which is where the three rate-up characters and three rate-up Light Cones come into play. You can spend Star Rail Special Passes or Stellar Jade on the warp, and the featured selection resets when phase two of Version 4.5 begins.
