Honkai Star Rail 4.7 leaks reveal Aeon Aha and EX Eidolons

Data-mined files from the Honkai: Star Rail version 4.7 beta reveal the complete Elation kit for the upcoming five-star character Aeon Aha. The leaks also detail a brand-new EX Eidolons upgrade system for older characters and two Planar Ornament sets. Version 4.7 is expected to launch across all platforms on November 11, 2026, following the current patch cycle.

Aeon Aha Wishpower and Elation mechanics

HoYoverse officially confirmed Aeon Aha as a playable Quantum character on September 15, 2026, but specific kit details come from unconfirmed beta data. Aeon Aha functions as an Elation-focused unit whose ultimate relies on a unique resource called Wishpower instead of standard energy. Wishpower is generated through basic attacks, skills, and team Punchline triggers. The ultimate fires once eight points are accumulated. The character can also mark one target ally as an Emanator of Elation, which boosts their damage and launches a coordinated Quantum attack. Furthermore, a percentage of damage dealt by teammates is collected as Elation Debt and converted into true damage that ignores enemy defense.

EX Eidolons legacy upgrade system 

The beta introduces a new upgrade path called EX Eidolons, which beta files also call Affinitive Eidolons. This system aims to buff older characters without requiring players to pull duplicate copies from the warp banner. Players unlock these nodes using Affinitive Eidolon materials earned through events, login campaigns, or exchange shops. Leaked records indicate that Acheron, Jing Yuan, and Dan Heng Imbibitor Lunae will be the first legacy characters to receive these targeted upgrades.

Leaked Planar Ornaments and banner reruns 

The beta files contain data for two new Planar Ornament sets. The Subspace ASC Center set grants an 18 percent Break Effect buff to all allies when the wearer reaches 145 speed or higher. The Gods Moment of Joy set advances the action of the wearer by 40 percent at the start of battle if the team Elation gauge reaches a specific threshold. Finally, data miners currently list Silver Wolf, Sparxie, and Yao Guang as the primary rerun candidates expected alongside Aeon Aha.
