In Honkai: Star Rail Version 4.1, you continue the Trailblazer’s journey through Planarcadia as the story expands into new areas. The update introduces Ashveil as a new playable character and features a Mecha Pom-Pom boss alongside additional mech-themed enemies.
You experience all of this within a shorter-than-usual patch cycle, which changes how you plan your pulls, resources, and progression. Version 4.1 delivers focused content while pushing the narrative and combat challenges forward.
Honkai Star Rail Version 4.1 Release Date and Duration
You can access Version 4.1 starting March 25, 2026, after a short maintenance period. Once servers reopen, check your in-game mailbox to collect the standard maintenance compensation.
This update runs for four weeks, which is shorter than the usual six-week cycle.
| Item | Date |
|---|---|
| Update Launch | March 25, 2026 |
| End Date | April 21, 2026 |
| Patch Length | 4 Weeks |
The compressed schedule helps realign the overall update timeline following the extended 3.8 cycle.
Ashveil
You deploy Ashveil, a 5-star Lightning unit who follows The Hunt, when you need focused single-target damage. His kit centers on sustained pressure against one priority enemy rather than wide-area control.
He applies a special mark called “Bait” to a chosen target.
When your allies strike that marked enemy, he immediately triggers a Follow-Up Attack, adding extra Lightning damage without consuming your turn.
This mechanic rewards coordinated team rotations and frequent hits on the same foe.
| Role | Element | Path | Strength |
|---|---|---|---|
| Main DPS | Lightning | The Hunt | Single-target burst & follow-ups |
If you progressed through Planarcadia in Version 4.0, you have already encountered him in the story.
His Warp banner runs for the full four-week duration of Version 4.1.
Mecha Pom-Pom Boss
You face a new Imagenae threat in the form of Alloy Mechatron: King Pom-Pom, a mechanical boss built around heavy armor and direct assaults. Its design reflects a full combat conversion rather than a standard mascot form.
Alongside this encounter, you battle members of the Daybreak Squadron, a group defined by their machine-based frames and coordinated attack patterns. Expect structured phases and pressure from multiple mech-style units.
Fresh Zones and New Planar Ornament Sets in HSR 4.1
Version 4.1 opens two additional locations in Planarcadia: Lookout Cloud Station and Pearluxe Tower. You can explore new pathways, enemies, and event interactions across both zones when the update launches on March 25, 2026.
Alongside these areas, you gain access to two new Planar Ornament collections.
Punklorde Stage Zero

- When Elation reaches 40% / 80% for the first time in battle, your CRIT DMG increases by 20% / 32%.

- 2-Piece Effect: Using a Follow-Up ATK boosts your ATK by 24% for 2 turns.

You can use this set to strengthen Follow-Up ATK strategies, including units like Ashveil, while also improving older follow-up damage dealers.
