Aeon ★ Aha's Best Light Cone

These are the best Light Cones to build for Aeon ★ Aha.

Upon the First Echo of "Aha" (S1)
117.5%

Increases the wearer's base Speed by 12.0 / 14.0 / 16.0 / 18.0 / 20.0. When using a Skill on one other ally, gains 10.0 / 12.0 / 14.0 / 16.0 / 18.0 Punchline. This effect can trigger at most once every interval of 1.0 turn(s). Then, causes all allies to ignore 16.0 / 18.0 / 20.0 / 22.0 / 24.0% of the enemy target's DEF when dealing DMG during this combat. This effect cannot be stacked.

Aha's signature Light Cone and expected to easily be her best-in-slot build option, providing a new method to increase Punchline generation alongside an increase to base SPD and a party-wide DEF ignore.

Mushy Shroomy's Adventures (S5)
100%

Increases the wearer's Elation by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%. When the wearer uses an Elation Skill, increases Elation DMG taken by all enemies by 6.0 / 7.0 / 8.0 / 9.0 / 10.0% for 2 turn(s).

A free-to-play baseline option. It provides a flat Elation% increase and adds an Elation DMG-taken debuff on enemies whenever Aha uses her Elation Skill. A perfectly serviceable choice if you don't have her Signature.

Elation Brimming With Blessings (S5)
96.7%

Increases the wearer's ATK by 20.0 / 25.0 / 30.0 / 35.0 / 40.0%. After the wearer uses Skill or Ultimate on one ally character, increases the target's Elation stat by 12.0 / 15.0 / 18.0 / 21.0 / 24.0% for 2.0 turn(s).

A free-to-play option from Herta's Store. It provides a Elation% increase to one ally when Aha uses her Skill on them. She does not care for the ATK%. A perfectly serviceable choice if you don't have her Signature.

See You at the World's End! (S5)
95.8%

For every Elation character on the team, increase the wearer's CRIT DMG by 6.0 / 7.0 / 8.0 / 9.0 / 10.0%. When Aeon ★ Aha is on the field, the wearer's CRIT DMG additionally increases by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%.

A decent gacha option. It provides CRIT DMG % for every Elation character in the team, and even more CRIT DMG % per Elation character if Aha is on the field.

Best Relics and Planar Ornaments for Aeon ★ Aha

Best Relics for Aeon ★ Aha

These are the best Relic Sets to build for Aeon ★ Aha.

Dreamlit Actor

2-Piece Set: Increases SPD by 6.0%.

4-Piece Set: When the wearer uses their Skill or Ultimate on one other ally target, increases the ability target's Elation by 16.0%, lasting for 3 turn(s). If the wearer has 10 or more points of Certified Banger, additionally increases all ally targets' CRIT DMG by 12.0%, lasting for 3 turn(s).

Aha's best all-around Relic Set. Using her Skill or Ultimate on an ally raises their Elation by 16% for 3 turns, and once Aha has 10 "Certified Banger," it also grants the whole team 12% CRIT DMG.

Diviner of Distant Reach

2-Piece Set: Increases SPD by 6.0%.

4-Piece Set: Before entering combat, if the wearer's SPD is greater than or equal to 120/160, increases the wearer's CRIT Rate by 10.0%/18.0%. When the wearer uses Elation Skill for the first time in each battle, enhances all allies' Elation by 10.0%. This effect cannot stack.

The CRIT Rate it grants does much for Aha, especially since she doesn't have many sources of it. While only one Elation ally can equip it at once, if isn't in the team, she wears it incredibly well.

Best Planar Ornaments for Aeon ★ Aha

These are the best Planar Ornament Sets to build for Aeon ★ Aha.

God's Moment of Joy

2-Piece Set: Increases the wearer's SPD by 6.0%. When the wearer's Elation reaches 40.0% or higher, the wearer's action advances by 40.0% immediately when entering combat.

One of Aha's best Planar Ornament sets, providing not just a flat SPD increase, but also the same 40% action advance as Vonwacq.

Sprightly Vonwacq

2-Piece Set: Increases the wearer's Energy Regeneration Rate by 5.0%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40.0% immediately upon entering battle.

A decent choice, but she does not benefit from Energy Regeneration Rate%.

Aeon ★ Aha Build Comments

Aeon ★ Aha acts is the final piece Elation team, revolving around gaining "Wishpower" to jumpstart "Faces of Elation" and enable massive buffs.

Their Skill designates a primary ally as the "Emanator of Elation," immediately following up with a FUA, then boosts the ally's Elation while allowing them to generate Wishpower at the start of their turns. Once Wishpower reaches 8 points, Aha may trigger "Aha! Let There Be Laughter," advancing the Aha Instant's action, increasing their damage, transforming like Punchline into the refunding Bliss and Party Trick states during battle. Furthermore, they innately buff each Elation character during her "Faces of Elation" status.

Between THEIR Eyes and Yours	28%	57%	Increases all the Elation character-specific buffs by a large amount.
A Stacked Deck of Sorrow and Joy	1%	58%	Pure trace level-ups to Ultimate, Basic ATK, and Elation Skill.
A Joke's Fate Boxed in Black	10%	74%	Strengthens her personal DMG by dealing damage based off everyone's Banger, as well as increasing her TRUE DMG multiplier.
Moi Onstage and Me Offstage	1%	75%	Pure trace level-ups to Skill, Talent, and Elation Skill.
For THEY Said: You Are Elation	14%	100%	Increases Elation Debt and significantly buffs the first Ultimate, as well as the natural Aha Instant after.
