Honkai: Star Rail Version 4.5 Preview — Astropolis on August 26

Last updated:

Version 4.5 is live. The patch leaves disaster-stricken Planarcadia for Astropolis, an Interastral Peace Corporation resort city, and debuts summer variants of Robin and Aventurine across two banner phases. Use this preview for the schedule, then open the launch post for live builds.

When Version 4.5 goes live

Version 4.5 “To Roll the Stars in Astropolis” launches August 26, 2026 on PC, mobile, and PlayStation. Expect the usual maintenance window before servers reopen. Bank Stellar Jade from remaining August codes now — the Version 4.5 livestream batch already expired on August 15.

  • Launch date: August 26, 2026
  • Redeem leftover codes on /star-rail-codes before maintenance
  • Summeretto and Waveflair build pages are live on StarPatch

Banner phases: Summeretto then Waveflair

Phase 1 opens with Robin • Summeretto, a 5-star Wind Remembrance unit, alongside a Hyacine rerun. Phase 2 starts September 12 with Aventurine • Waveflair and an Ashveil rerun. Signature Light Cones Rise and Sing and Summer Rides the Surf headline each half. If your account still lacks a sustain or Harmony support, weigh those gaps against a limited summer debut before dumping every pass.

  • Phase 1 (August 26): Robin • Summeretto + Hyacine rerun
  • Phase 2 (September 12): Aventurine • Waveflair + Ashveil rerun
  • Check the tier list before locking a first-half pull plan

Astropolis story and what to farm first

The Trailblaze Continuance sends the Express to Astropolis to seek IPC aid after the Voracity crisis on Planarcadia. A later summer vacation chapter follows Robin and Aventurine in the same city. Finish current traces and Light Cones on your live teams before the patch — relic domains can wait until you know which new sets or enemies 4.5 actually asks you to clear.

  • Prioritize levels and traces on one clear team
  • Hold spare Trailblaze Power if a new relic set ships with 4.5
  • Follow the Version 4.5 launch post for live builds and tier moves
