Honkai: Star Rail’s version 4.5 livestream revealed upcoming summer-themed character variants and issued three limited-time redemption codes for free Stellar Jade and materials. The update matters chiefly to players seeking early details of the next patch and time-sensitive in-game rewards.

Version 4.5 introduces Aventurine Waveflair as a Quantum Nihility character and Robin Sumeretto as a Wind Remembrance character, both linked to Penacony. The livestream also teased a winter 2026 collaboration with Zenless Zone Zero; the three codes expire on 15 August at 11:59am EDT, and can be redeemed in-game or through the official website with a valid account, server selection and UID.
