How the kit works
Before combat, ABRACADABRA! creates a dimension for 20 seconds. Enemies inside cannot detect allies. On entering combat, Aha gets an extra turn that takes 20 Punchline into account without consuming it. Only one allied dimension can exist at a time.
Use This Emanator Was Certified by Aha™ on another ally to give them Emanator of Elation. They gain 20% Elation and give Aha 1 Wishpower at the start of each of their turns. The state lasts until you move it to someone else. The Skill also launches a Follow-up ATK against all enemies. A Prank on Aeons adds Elation DMG matching the chosen ally's type and recovers 1 Skill Point.
Starfrost, Showtime! hits one enemy. Basic, Skill and Elation Skill each give Aha 1 Wishpower. Work Wonders with THEM allows the Ultimate at 8 Wishpower, with overflow up to 10. When allies' Punchline first reaches 40, Aha gains another point and gives allies 40% CRIT DMG for 3 turns; this can trigger again after Aha's turn ends.
Use Aha! Let There Be Laughter when it is available to hit every enemy, followed by five hits on random enemies. It advances Aha's action by 20% and grants Faces of Elation for 3 turns. During this state, allies' Path of Elation ascends, Punchline becomes Bliss and Certified Banger becomes Party Trick. Aha gains 20% CRIT Rate and ignores 60% of enemy DEF when dealing damage. Bliss recovers 10% of the amount consumed when Aha Instant ends.
At the end of Aha Instant, Yes Aha At Full Moon hits all enemies and deals True DMG based on 20% of the non-True DMG dealt by allies during that instant, divided evenly among enemies. The True Story of Aha also applies Elation Debt when Aha or a teammate deals damage; it persists through enemy phase transitions.
Build and why
Use four pieces of Dreamlit Actor with two pieces of God's Moment of Joy. Dreamlit Actor gives SPD and lets Aha's Skill raise its target's Elation by another 16% for 3 turns. With at least 10 Certified Banger, the set also gives the team 12% CRIT DMG. God's Moment of Joy gives SPD and advances Aha's action at the start of combat if Aha has at least 40% Elation.
Diviner of Distant Reach is a good alternative relic set. Its CRIT Rate depends on SPD before combat, and the first Elation Skill in each battle gives allies 10% Elation. For the body, use CRIT Rate or CRIT DMG; use SPD on the feet. HP Percentage or DEF Percentage works on the sphere and rope. Prioritize CRIT Rate, CRIT DMG, then SPD in substats.
Keep the SPD thresholds from A Box of Everything in mind: 125 SPD gives Aha 120% Elation, while 150 SPD gives 150%. The same passive advances Aha's action by 30% when combat starts.
Upon the First Echo of "Aha" is the first weapon choice. It adds 12 base SPD, gives Punchline when Aha uses Skill on another ally, and lets allies ignore 16% of enemy DEF. Tomorrow, Together is an alternative that gives CRIT DMG and raises team Elation after the Ultimate. Mushy Shroomy's Adventures gives Aha Elation and increases the Elation DMG enemies take after an Elation Skill.
Leveling priority
Follow the game's order: level Work Wonders with THEM first, then Yes Aha At Full Moon, This Emanator Was Certified by Aha™, Aha! Let There Be Laughter, and finally Starfrost, Showtime!. The Talent supports Wishpower and the team CRIT DMG effect; the Elation Skill contributes damage at the end of Aha Instant.
For maximum ascension, you need 308,000 Credit, 65 Sneering Harlequin, 15 Whimsy Wax, 15 Dreamweave Steel and 15 Lucid Awl.
For all skills, you need 3,000,000 Credit, 8 Tracks of Destiny, 18 The Fluffy Hand-drawn Storyboards, 69 The Fluffy Serialization Memorial Issue, 139 The Fluffy Collector's Edition and 12 High Hopes of the Falsely Enlightened. You also need 41 Whimsy Wax, 56 Dreamweave Steel and 58 Lucid Awl.
Eidolons worth it
One possible priority is For THEY Said: You Are Elation, Who Giggled at the Primordial Hush?, then A Joke's Fate Boxed in Black. E6 makes enemies carry Elation Debt claiming at least 20% of their Max HP. After Aha's first Ultimate, it also advances Aha's action by 100% and grants 100 Punchline.
E1 is an earlier stopping point worth considering: Aha starts combat with 5 Wishpower, and allies' Elation DMG merrymakes by 15%. E4 increases the Elation Skill's True DMG multiplier by 25% of its original value and makes Aha's Elation DMG take an extra 100% of teammates' Certified Banger into account.
Between THEIR Eyes and Yours enhances Path Ascension, but its further effects are not specified here. The level increases at E3 and E5 can be lower priorities as standalone goals. You still pass through earlier Eidolons when pursuing a later one, and you can stop before E4 or E6 if you do not want to go that far.
Teams
An Elation teammate is a good recipient for Emanator of Elation. Their turns give Aha Wishpower, and Aha's Ultimate state lets allies' Path of Elation ascend. The Skill's extra Elation DMG also matches the recipient's combat type, so the ally's element affects that part of the hit.
Consider a teammate who can heal Aha or provide a Shield. A Carnival in Whimsy gives Aha 1 Wishpower on receiving either from a teammate, once until the Ultimate resets the trigger. The rest of the team can focus on dealing damage: Yes Aha At Full Moon uses allies' non-True DMG during Aha Instant to calculate its True DMG.
Common mistakes
Do not use Skill without checking its recipient. Emanator of Elation stays on the chosen ally until you switch it, and that ally's turns provide Wishpower. If someone else needs the Elation boost, move the state deliberately.
Do not ignore SPD while chasing CRIT stats. The 125 and 150 SPD thresholds give Aha Elation, and God's Moment of Joy has its own 40% Elation requirement for its opening action advance. Check the conditions on your chosen sets rather than assuming every bonus is always active.
Do not treat Wishpower and Punchline as the same resource. The Ultimate becomes available at 8 Wishpower, while the Talent's team CRIT DMG trigger checks allies' Punchline at 40. Aha can hold up to 10 Wishpower, so a point gained above 8 is not immediately wasted.
