Summary
The first playable Aeon in Honkai Star Rail is no longer a meme. Version 4.7 Phase 1 headlines Aha, a five-star Quantum Harmony unit on the Path of Elation, and the version-one beta leak shows a kit that is less a traditional support and more a full archetype enabler. Aha replaces energy with a new resource called Wish Power, marks one ally as the Emanator of Elation, and unlocks a three-turn "Faces of Elation" state that ascends every Elation character on the team at once. Early reads call her the Elation battery the path has been missing — and a global passive that quietly raises the base speed of every Aha Instant you trigger. For players preparing to build her, Honkai: Star Rail Top Up can also be part of the resource planning for the 4.7 release.
Release Window and What Is Confirmed
Version 4.6 is live now, with Pearl in Phase 1 and Mortax Blade in Phase 2. It runs until November 10 or 11 depending on server. Version 4.7 launches the very next day, and Aha headlines Phase 1.
The drip marketing from September 15 confirms the basics: five-star, Quantum, Path of Elation. Everything else in this guide is version-one beta data. Numbers will move between now and release, and the community is treating this as a first snapshot, not a final verdict.
Wish Power and the Skill That Marks an Emanator
Aha does not use energy. Her ultimate costs eight Wish Power, and she generates it from many small sources: her own basic attack, skill, and Elation skill; the first time the team hits 40 Punchlines; each turn start of her marked Emanator; and whenever she is healed or shielded.
Her skill marks a single ally as the Emanator of Elation for the rest of battle, instantly launching a follow-up at every enemy. The Emanator gains 20% Elation damage, and a trace makes the follow-up also deal 20% Elation damage based on the Emanator's type while refunding one skill point. Her Elation skill hits all enemies for 60% Elation damage, then adds true damage equal to 20% of the total damage dealt during the Aha Instant. Another trace scales her Elation damage with speed, capping at 150% at 150 speed.
Faces of Elation: The Ascension State
At eight Wish Power, Aha fires her ultimate: 200% Quantum damage to all enemies, followed by five random 60% bounces, then enters Faces of Elation for three turns. This is where the kit's real power lives.
While active, Punchline converts into Bliss, which refunds 10% of the Punchline consumed at the end of the Aha Instant. Certified Banger converts into Party Trick. Aha ignores 30% of enemy defense. Most importantly, every Elation ally ascends with a unique buff: Pearl's Party Trick cap rises to 75 and retains 10% of resources on her extra turn; Eva stores up to 60 overflow energy and gains 50% ult multiplier per 500 Party Tricks; Silver Wolf pushes to 360 RES PEN with 40% crit damage; Yao Guang's Great Boon multiplier climbs 20%; Sparksy gains 30% crit damage; the Elation Trailblazer's crit boost applies to the whole team; and even a solo Venturine gets his solo-Elation trace enhanced with +15% party speed.
Elation Depth and the True Damage Hook
The most discussed mechanic in the leak is Elation Depth. While Faces of Elation is up, Aha and her teammates apply an extra damage share based on the damage they deal. It is capped at 10% of the enemy's max HP and, crucially, carries through phase transitions. When the boss's HP drops to the Depth threshold, it triggers as a chunk of bonus damage — effectively a built-in execute against multi-phase fights.
Her Elation skill also converts a slice of the Aha Instant's total damage into true damage, split across enemies. Between the true damage, the Depth execute, and the defense shred, Aha's personal numbers look solid for a secondary dealer at Eidolon zero, even if she is not built as a main carry.
The Global Passive and the Light Cone Debate
The kit's most controversial line is the global passive: when Aha is owned or on the team, the base speed of the Aha Instant rises from its fixed 80 to Aha's own base speed of 94. Her signature light cone, "Upon the First Echo of Aha," adds another 12 base speed — meaning the light cone buffs the global passive. This is the first offensive global passive in the game, and the community is split on whether it sets a bad precedent for future versions.
Eidolons and the Pull Decision
Aha's kit is complete at Eidolon zero. E1 gives all allies 15% Elation damage and starts her with four Wish Power, speeding up her first ultimate. E2 is the famous breakpoint: it supercharges every Ascension effect — Silver Wolf to a theoretical 999 RES PEN, Sparksy crit damage from 30% to 120%, Eva's overflow energy from 60 to 240. Players already call E2 baseline for the highest-end Elation teams. E3 and E5 are skill levels, E4 boosts the true damage, and E6 guarantees enemies always carry a minimum Depth and chain her later ultimates.
The pull logic is straightforward. If Elation is your main team and you have already invested in it, she is a must-pull. If you do not care about the path, skip. E0 is fully functional; E2 is for players deep in the Elation rabbit hole who want future-proofing. Wait for later beta versions before spending — numbers will move.
Final Verdict
Aha arrives as the archetype-defining support Elation players have wanted since the path launched. The Wish Power loop, the Emanator mark, and the Faces of Elation state turn every existing Elation unit into a better version of itself, and Elation Depth gives the team a real multi-phase execute.
The warning sign is the global passive. It is narrow enough (Elation-only) and Aha is strong enough on her own that pulling her for the passive alone is not the play — but it opens the door to more aggressive global effects in 5.x. Treat the 4.7 release as a strong, well-scoped character for Elation mains, and keep one eye on whether future patches turn that door into a highway. Players planning to pull and build Aha can also buy Honkai: Star Rail Top Up to help cover the resources needed for her progression.
