Aeon ★ Aha Build Guide: Kit, Eidolons & Best Teams (HSR 4.7)

Numbers in this guide follow the latest V3 beta data. Aha's kit is final only when Version 4.7 goes live, and we will update any value that changes.

01Aeon ★ Aha Overview: Release Date, Banner & Stats

Timing works in Aha's favor: Silver Wolf LV.999, Sparxie and Yao Guang, three of her best Elation partners, rerun in 4.7 Phase 1 (until December 2). Acheron, Dan Heng • Imbibitor Lunae and Jing Yuan follow in Phase 2, and one of those three is free to claim. Full dates are in our HSR banner schedule.

02Aha Kit Explained: Skills, Traces & V3 Changes

Basic ATK: Build Wishpower

Deals 50% Quantum Elation DMG to one enemy and gives Aha 1 Wishpower. Use it when you need Skill Points without stalling her Ultimate.

Skill: Mark Your Emanator of Elation

Gives one ally the Emanator of Elation state, then launches a follow-up attack for 50% Quantum Elation DMG to all enemies.

• The marked ally gains 20% Elation and gives Aha 1 Wishpower at the start of each of their turns.
• The mark lasts all battle until you move it to someone else.
• Since V3, Aha cannot target herself, so always mark Silver Wolf LV.999 or your main Elation DPS.

Talent: The Wishpower Engine

Aha's Ultimate ignores Energy. It unlocks at 8 Wishpower, which she gains from her Basic ATK, Skill and Elation Skill, plus her Emanator's turns. The first time allies reach 40 Punchline, Aha gains 1 Wishpower and all allies get +40% CRIT DMG for 3 turns. Damage from Aha and her teammates also applies extra Elation Debt equal to 25% of the damage dealt. When combat starts, Aha takes an extra turn that adds 20 Punchline, which helps your team reach its first Aha Instant sooner.

Ultimate: Faces of Elation

Advances Aha's action by 20%, deals 200% Quantum Elation DMG to all enemies plus 5 random hits of 60%, and grants Faces of Elation for 3 turns. During this state, every Elation ally's Path ascends: Punchline becomes Bliss (refunding 10% of Punchline spent) and Certified Banger becomes Party Trick. Aha also gains 12% CRIT Rate and ignores 30% of enemy DEF.

Elation Skill: AoE + True DMG

Always fires at the end of an Aha Instant. It deals 60% Quantum Elation DMG to all enemies, then True DMG equal to 20% of the non-True damage your team dealt during that Aha Instant, split evenly among enemies.

Aha Instant Passive and Traces

Owning Aha raises the base SPD of Aha Instant from 80 to Aha's own base SPD, even when she is not in the lineup. Her active skills still only work on the field. Key Traces:

• A Carnival in Whimsy: gains 1 Wishpower when a teammate heals or shields her.
• A Box of Everything: at 125 / 150 SPD, her Elation rises by 120% / 150%. Since V3, it also advances her action by 30% when combat starts.

What Changed From V1 to V3

V3 also buffed several allies' Faces of Elation effects. Yao Guang's Ultimate restores a fixed 12 Energy (30 at E2) and adds 10 Punchline. Sparxie's Elation Skill gains +50% of its original DMG multiplier (120% at E2). Evanescia's Ultimate DMG buff rises to 75% (150% at E2).

03Best Eidolons: Where Should You Stop?

E0 already unlocks Aha's full core kit: the Emanator mark, Wishpower, Faces of Elation and the Aha Instant SPD passive. Eidolons make her faster to open and stronger in the Faces of Elation window.

Eidolon	Effect (V3)	Verdict
E1	Starts combat with 5 Wishpower; all allies deal 15% more Elation DMG.	Best first upgrade. Much faster first Ultimate.
E2	Stronger Faces of Elation: Aha's CRIT Rate bonus rises to 20% and her DEF ignore to 60%, and each Elation ally's ascended effect is upgraded (for example, Yao Guang's Energy 12 → 30).	Premium team breakpoint.
E4	Elation Skill True DMG multiplier +25%; Aha's Elation DMG also counts 100% of teammates' Certified Banger stacks.	More personal damage.
E6	Reworked in V3: Aha's first Ultimate advances her action by 100% and adds 100 Punchline.	Whale-only opener.

04Best Aha Teams: Three Elation Setups

TEAM 1 · HYPERCARRY

Aha + Silver Wolf LV.999 + Sparxie + Pearl

Aeon Aha

Silver Wolf LV.999

Sparxie

Pearl

Silver Wolf LV.999 is the main carry. Pearl keeps the team alive, and her heals and shields also trigger Aha's Wishpower Trace. Silver Wolf and Sparxie both rerun in 4.7 Phase 1.

1. Mark Silver Wolf LV.999 as Aha's Emanator.
2. Build Punchline with Sparxie and Wishpower with the team.
3. Cast Aha's Ultimate to open Faces of Elation.
4. Spend the window on upgraded Party Trick, Hidden MMR and Silver Wolf's Godmode Player turn.

Pros: highest burst and the cleanest Emanator target. Cons: three limited 5-stars plus Pearl.

TEAM 2 · FULL ELATION

Aha + Sparxie + Evanescia + Yao Guang

Aeon Aha

Sparxie

Evanescia

Yao Guang

The team that gained most from V3. During Faces of Elation, Yao Guang's Ultimate refunds Energy and adds Punchline, Sparxie's Elation Skill hits harder, and Evanescia's Ultimate buff rises. The result is very frequent Aha Instants. It costs a lot of limited characters and has no dedicated sustain.

05Best Light Cone, Relics & Stats

Signature Light Cone: Upon the First Echo of "Aha"

At S1 it grants +12 base SPD. Using her Skill on another ally gives Punchline (with a cooldown), and all allies ignore 16% enemy DEF. It is featured on the Brilliant Fixation Warp for all of Version 4.7. Strong, but not required: E0 already plays the full kit.

Relics & Planar Ornaments

Trace priority: Talent = Elation Skill > Skill = Ultimate > Basic ATK.

06Should You Pull Aha? The Quick Verdict

Two things to know before pulling: Aha is not the free 4.7 5-star (that pick is Acheron, Dan Heng • Imbibitor Lunae or Jing Yuan), and pity built on Pearl or Mortenax Blade in 4.6 carries over to her banner.

Final Take: Is Aha Worth It?

After the V3 buffs, Aha is the strongest Elation support so far: faster Aha Instants, a 40% team CRIT DMG buff and Faces of Elation upgrades for every Elation ally. If you already invested in Sparxie, Evanescia or Silver Wolf LV.999, she is an easy pull. If not, decide alongside the Phase 1 reruns, since she needs Elation teammates to shine.
