Harmony
Imaginary5★ “There’s always a paradise that needs to be built. That vow is like the sun in the sky. Perhaps I’ll melt and fall before reaching it… But some hardships I must endure.”
Sunday is a Harmony support who specializes in pulling one ally's turn forward. His Skill lets that ally and their summon act immediately, with a DMG boost and extra CRIT Rate on top. His Ultimate restores Energy to the chosen ally and raises their CRIT DMG. If you want someone to advance and heavily buff your main DPS, Sunday is well worth pulling.
He fits best with summon DPS like Jing Yuan or Aglaea, since he advances their summons too and buffs them harder. Hypercarry teams built around one DPS also use him well, but Break and DoT teams already have better supports.
This is the most common way to build him. Sunday wants CRIT DMG because the CRIT DMG his Ultimate gives an ally scales off his own CRIT DMG, plus SPD for tuning and Energy Regeneration Rate so his Ultimate comes back on time.

CRIT DMG body makes his Ultimate's buff stronger. SPD boots for speed tuning. HP% or DEF% on the Planar Sphere, the two are equal. Only take Energy Regeneration Rate on the Link Rope, since Sunday has to get his Ultimate back before the 3 turns of The Beatified run out.
Hit your SPD target first, then pile on CRIT DMG. Effect RES matters if you use Broken Keel, since that set needs at least 30%.
All three support abilities matter about equally. If you are short on materials, level his Skill first to raise its DMG buff, then his Ultimate to raise the CRIT DMG he gives, then his Talent to raise the CRIT Rate on his Skill target. Basic ATK doesn't matter, so leave it for last.
Unlock all three early. Rest Day's Longing makes his Ultimate restore at least 40 Energy, which is huge for allies with cheap Ultimates. Exalted Sweep gives Sunday 25 Energy at the start of battle so his Ultimate comes up sooner. Haven in Palm dispels 1 debuff when he uses his Skill, which is useful in any fight.
Sunday plays fine with no Eidolons. E1 lets his Skill target ignore 16% of enemy DEF and their summon ignore 40%, lasting 2 turns, which is a big damage increase. E2 recovers 2 Skill Points after his first Ultimate and makes The Beatified deal 30% more DMG. E4 regenerates 8 Energy at the start of each of his turns, so Energy is less of a worry. E6 lets the Talent's CRIT Rate stack up to 3 times and last 1 extra turn, his Ultimate can apply it too, and if the target's CRIT Rate goes over 100%, every 1% of excess CRIT Rate adds 2% CRIT DMG.
This build makes Sunday as fast as possible. He keeps pulling his buffed ally up with him, so that ally ends up acting at Sunday's SPD and can skip SPD entirely to stack damage stats.

Same main stats as the standard build, still with SPD boots.
Stack as much SPD as you can. Everything else follows the standard build.
One of the most popular Sunday teams. Sunday advances Himeko • Nova and restores her Energy so she gets to act more. You can run Himeko • Nova at 135 SPD with Sunday at 134, or push Sunday to 160 or more so Himeko • Nova stays at base SPD and wears ATK% boots. Dan Heng • Permansor Terrae attaches his summon to the ally he picks, so that ally gets the full, larger DMG boost from Sunday's Skill. Sparkle's slot can go to Robin • Summeretto, Welt, Tribbie, Mortenax Blade or Trailblazer (Remembrance).
A sample team for putting every buff on one DPS. Sunday works with almost any hypercarry like this thanks to his turn advance and DMG buffs. Boothill is the exception among Break characters, since he likes extra turns and a support who doesn't eat Skill Points. Tribbie gives the whole team All-Type RES PEN. With Sparkle, both need 160 SPD or more and Sparkle has to act before Sunday. With Bronya, your DPS should only use 1 Skill Point per turn, Bronya acts after Sunday and your DPS acts before him. Gallagher is a good fit when you run Sunday with Sparkle or Bronya, because he helps the team stay Skill Point positive.
Sunday can advance summons as well, which makes him a great partner for DPS who rely on summons like Aglaea or Jing Yuan, and he buffs them harder too. Robin adds more offensive buffs and another advance with her Ultimate, so the team gets a lot of extra turns. Huohuo heals and restores Energy to the whole team. Castorice gets almost nothing from the Energy, but Sunday's other buffs still make her and her memosprite stronger.
Sunday gives the main DPS extra turns, buffs and Energy, so they act more often and trigger a partner like Jade more often too. Other pairings that work the same way: Jade with Xueyi and Fu Xuan, Blade with Jade and Luocha, March 7th (The Hunt) with Feixiao and Aventurine, or Herta with Himeko and Huohuo.
Sunday is Jing Yuan's best support and currently the only one who can advance his Lightning-Lord, which fixes the problem of his slow summon. His Skill also cleanses debuffs. Play Sunday in the 1 SPD slower setup for this pair.
A summon DPS, so Sunday advances both her and her summon, and she gets the extra DMG buff and Energy.
One of the action advance supports that suit her. His Ultimate's Energy plus the advance let Himeko • Nova act and use her abilities more.
Sunday's turn advance and Energy restoration help Phainon a lot, and his Skill, Ultimate and advance generate plenty of Coreflame for him. Phainon also badly needs the CRIT Rate Sunday gives. On top of that, Sunday's Technique buff can last through Phainon's first Ultimate.
He attaches a summon to his chosen ally, so that ally gets the full, larger DMG boost from Sunday's Skill even without a summon of their own. His summon gets advanced along with the target, refreshing Shields on the team again and again.
The Energy restoration does almost nothing for Castorice, but Sunday's other buffs still make her and her memosprite stronger.
Can share a team, but both need 160 SPD or more and Sparkle has to act before Sunday, so speed tuning is required.
Can share a team if your DPS only uses 1 Skill Point per turn, otherwise you run short on Skill Points. Bronya acts after Sunday and your DPS acts before him.
His Skill, Benison of Paper and Rites, makes one ally and their summon (for example Jing Yuan's Lightning-Lord or Topaz & Numby's Numby) take action immediately and raises their DMG dealt for 2 turns. If the target has a summon, the DMG boost is even bigger. His Talent, The Sorrowing Body, also gives the target extra CRIT Rate for 3 turns.
Because the buff lasts 2 turns, characters who attack outside their own turn with Follow-up ATKs or counters get a lot out of it too. Keep in mind that a Harmony character targeted by his Skill still gets the buffs but is not advanced. The Trace Haven in Palm also dispels 1 debuff from the target, so an ally you just advanced doesn't end up unable to act.
His Ultimate, Ode to Caress and Cicatrix, costs 130 Energy. It restores Energy equal to 20% of one ally's Max Energy (at least 40 thanks to Rest Day's Longing) and turns that ally and their summon into The Beatified. The Beatified gain CRIT DMG that scales off Sunday's own CRIT DMG. It lasts 3 turns and loses 1 turn at the start of each of Sunday's turns. It only applies to the most recent target of his Ultimate, and if Sunday is knocked down, The Beatified is dispelled.
The nice part is that every time he uses his Skill on The Beatified, Sunday recovers 1 Skill Point, so the Skill is effectively free. To keep that going, The Beatified has to stay up without gaps, which means he needs his Ultimate again within 3 turns. That is why Sunday wants an Energy Regeneration Rate rope and an Energy-restoring Light Cone. Without them, you depend on getting hit by enemies or on Energy supports like Huohuo.
1 SPD slower than your DPS: your DPS acts right before Sunday, then Sunday uses his Skill so the DPS acts again in the same cycle. For example, if your DPS has 135 SPD, give Sunday 134. This is the most common setup and pairs well with Sacerdos' Relived Ordeal.
160 SPD or more: Sunday pulls his buffed ally to the front of the turn order and keeps them moving at his SPD, so your DPS can drop SPD for damage stats. Which one to pick depends on your DPS and how you like to play.
Deals Imaginary DMG equal to 140% of Sunday’s ATK to one designated enemy.
Enables one designated ally character and their summon to immediately take action, and increases their DMG dealt by 38%. If the target has a summon, then the DMG Boost effect is further boosted by an additional 63%, lasting for 2 turn(s).
After using Skill on The Beatified, recovers 1 Skill Point.
When Sunday uses this ability on characters following the Path of Harmony, cannot trigger the “immediate action” effect.

At the start of Sunday’s every turn, the duration of “The Beatified” decreases by 1 turn, lasting for a total of 3 turn(s). And it only takes effect on the most recent target of the Ultimate (excluding Sunday himself). When Sunday is knocked down, “The Beatified” will also be dispelled.
When using Skill, increases the target’s CRIT Rate by 25.0%, lasting for 3 turn(s).
After this Technique is used, the first time Sunday uses an ability on an ally target in the next battle, the target’s DMG dealt increases by 50%, lasting for 2 turn(s).
When Sunday uses Skill, the target character can ignore 16% of enemy target’s DEF to deal DMG and their summon can ignore 40% of enemy target’s DEF to deal DMG, lasting for 2 turn(s).

Talent Lv. +2, up to a maximum of Lv. 15.
The Talent’s CRIT Rate boost effect becomes stackable up to 3 time(s), and the Talent’s duration increases by 1 turn(s). When Sunday uses Ultimate, can also apply the Talent’s CRIT Rate boost effect to the target. When the Talent’s CRIT Rate boost takes effect and the target’s CRIT Rate exceeds 100%, every 1% of excess CRIT Rate increases CRIT DMG by 2%.
Sunday is a support character who can immediately advance the action of an ally and that ally’s summon. On top of that, Sunday can heal a chosen ally for a percentage of their HP while raising the DMG, CRIT Rate, and CRIT DMG of both that ally and their summon.
