Honkai: Star Rail's Version 4.0, titled "No Aha at Full Moon," launches on February 13, 2026, bringing a vibrant new world, fresh 5-star characters on the Path of Elation, generous free rewards, and quality-of-life upgrades. The update centers on Planarcadia, a entertainment-focused paradise ruled by games and clout, where Trailblazers chase "One Minute of Godhood" under the Aeon Aha's elusive gaze.
Welcome to Planarcadia: A New Planet of Endless Entertainment
Planarcadia is the star of Version 4.0, a revived 2D world turned IPC territory known for its neon-lit Duomension City and bizarre imagenae inhabitants like Meowton the station master and thundercoil signal boosters. The story kicks off with the Astral Express heading there for resupply at Himeko's suggestion, diving into the Phantasmoon Games - a chaotic competition established by Aha where winners claim momentary godhood. Expect Interplanar Jumps for platforming in shifting art styles, a hidden conspiracy involving Masked Fools, Xianzhou, and Stellaron Hunters, and later expansion to IPC's Astropolis resort.
New 5-Star Characters: Yao Guang and Sparxie Lead the Elation Path
Version 4.0 introduces the Path of Elation with two powerhouses built around "Punchline" stacks that trigger "Aha Instant" for massive team buffs and sequential Skill bursts.
- Yao Guang (5-star Physical / Elation): A Xianzhou seer strategist who draws Weal Lots for team boosts, Woe Lots to amp enemy damage taken, and Skill Point recovery. Her Ultimate grants Punchlines and All-Type RES PEN.
- Sparxie (5-star Fire / Elation): Planarcadia's top streamer who livestreams PK battles, consuming Skill Points for Gifts that build Punchlines and explode in AoE damage during Aha Instant lucky draws.
