Honkai Star Rail Aeon Aha release date is 11 November 2026. Version 4.7 makes Aeon ★ Aha playable as a limited five-star Elation character, with Wishpower, Aha Instant and a rare ability that lets teammates reduce enemies’ maximum HP.
Aha also takes centre stage in Planarcadia’s finale. If you’re deciding whether to pull, here’s what the character actually does, where the signature Light Cone fits in and why the Star Lotto costume is a separate reward.

HoYoverse confirms 11 November 2026 for Version 4.7, Now, Lay Laughter to All Stars. Aeon ★ Aha becomes a limited five-star character following the Path of Elation, no longer only a figure in the Planarcadia story.
Aha arrives with the new version on 11 November. The precise opening hour depends on the official server maintenance notice, so the release date is more useful for planning than a guessed UK countdown.
Honkai Star Rail Aeon Aha release date: How to get Aeon Aha
Aha is the new limited five-star released in Version 4.7, with a signature Light Cone called Upon the First Echo of Aha. The new warp is separate from the returning character selections advertised in the same programme.
The free gift available in the version is a choice of Acheron, Dan Heng • Imbibitor Lunae or Jing Yuan. Aha is not one of those free choices. Our banner guide covers both rerun phases.
Honkai Star Rail Aeon Aha release date: Wishpower and the Ultimate
HoYoverse says allies continually accumulate Wishpower for Aha in battle. Once it is full, Aha can unleash an Ultimate dealing Elation damage to all enemies. That links the power to the whole party rather than Aha alone.
Allies contribute to Aha’s Wishpower, and a full gauge triggers the area-of-effect Elation Ultimate. That’s the combat effect to keep in mind when building an Elation team, before more detailed skill numbers become available.
Aha Instant and Elation Skills
Aha Instant is a new named mechanic in which Aha takes the leading role and accelerates the performances of Elation Skills. The developer also says Aha boosts the potential of characters on the Path of Elation.
Aha Instant changes the timing of Elation Skill performances, giving this character a supportive role alongside their own attack. That makes them particularly interesting to players already investing in Elation allies.
How Aeonic Authority reduces maximum HP
Through Aeonic Authority, allied attacks can directly reduce an enemy’s maximum HP. That is not the same as merely lowering current HP with a normal hit, which is why the developer highlighted the effect.
Aeonic Authority is notable because it targets the enemy’s maximum HP, not just the amount remaining in the current HP bar. HoYoverse has confirmed the effect; its final scaling will be shown in the released character description.
Why Aha is central to Planarcadia
Aha directs the final Phantasmoon Games as the ancient leviathan the Voracity approaches full awakening. Eight Supplicants join a cosmic performance, and the dessert-shaped Starfroster carries the plan to lure the creature.
Aha steps into the battle with the Trailblazer rather than just overseeing it. The new version closes Planarcadia’s storyline and brings the animated short A Joyful Funeral Beneath the Moon on release day.
Honkai Star Rail Aeon Aha release date: Star Lotto outfit and the separate draw
Aha’s limited Star Lotto outfit is offered through the Phantasia Showstage event, not automatically included with the character warp. The official rules say the first draw is free and later draws require Fashion Invites.
The outfit is not guaranteed on that free attempt. The event runs from the 4.7 update to 23 December at 03:59 UTC+8; our Star Lotto outfit guide explains the separate draw and currency.
