Sunday Stats

Is Sunday Worth Pulling?

Sunday is an amazing support not just for DPS characters with Summons but also hypercarry DPS in general. Sunday gives your DPS and their Summon an extra turn using his Skill and increases their DMG. His Ultimate gives them Energy and increases their CRIT DMG.

He can also remove a debuff through his Skill and is SP-neutral. Pull for Sunday if you need a character who can advance Summons or extra turns and other offensive buffs for your hypercarry team.

Sunday's Best Builds

CRIT Buffer Build

Sunday's build needs CRIT DMG to strengthen the buff he gives to the DPS through his Ultimate. Sacerdos allows Sunday to boost an ally's CRIT DMG even further while giving him some SPD.

Having SPD is also valuable so Sunday can act more than once in one cycle. Make sure to have at least 30% Effect RES to activate the two-piece effect of the Broken Keel Ornament.

If Sunday uses But the Battle Isn't Over, you need use an Ornament that provides 5% Energy Regen and get hit once to guarantee a 3-turn Ultimate. Using A Grounded Ascent or an S3 But the Battle Isn't Over will allow you to 3-Turn Ultimate regardless of the 5% Energy Regen.

Recommended Stat Values

Stat	Recommended Value
CRIT DMG	200% or above
SPD	1 SPD slower than DPS 160 SPD

Building Sunday just 1 or 2 Speed slower than a DPS allows the DPS to act just before Sunday. Sunday then uses his Skill to enable the DPS to act again in the current cycle. For example, if your DPS has 135 SPD, build Sunday with 134 SPD.

You can also have Sunday with 160 SPD so he can bring your DPS at the start of the turn order. If Sunday has 160 SPD, your DPS can use other stats aside from SPD that increase their own damage.

Sunday's Best Teams

Sunday F2P Team (Free to Play)

Support	DPS	Support	Healer
Sunday	Any free DPS character	Asta	Lynx

Since Sunday is a universal Harmony character, you can pair him up with any of the free DPS characters. He gives them an extra turn and provides them with offensive buffs, while also restoring their Energy through his Ultimate.

Asta provides an ATK boost and more SPD for the whole party, which results in more turns. Lynx heals and cleanses debuffs for the party.

Sunday Summons Team

Support	DPS	Support	Sustain
Sunday	Jing Yuan	Robin	Aventurine

The team composition above is just an example of a Summons team.

Since Sunday can also Advance Forward Summons, this makes him a great support for DPS characters who rely on Summons like Jing Yuan. He also provides them with offensive buffs and restores their Energy.

Robin provides more offensive buffs and another Advance Forward on her Ultimate, which results in even more turns. Aventurine provides Shields and increases the CRIT DMG enemies take through his Ultimate.

With the Path of Remembrance on the way, having Sunday is great since it is expected that Remembrance characters will have Summons.

Sunday Hypercarry Team

Support	DPS	Support	Sustain
Sunday	Jingliu	Robin	Huohuo

The team composition above is just an example of a Hypercarry team.

Since Sunday is a universal Harmony character, you can put him in with any Hypercarry team composition and make it work thanks to his utility and offensive buffs.

You can use any Hypercarry DPS like Seele, Jingliu, Jing Yuan, and many others. However, Sunday falls off with Break or DoT characters since there are better supports for them.

Pairing Sunday with Robin works well because she brings even more offensive buffs. On top of that, she gives all allies an extra turn after using her Ultimate which results in even more turns for your hypercarry DPS.

Sunday Dual DPS Team

Support	DPS	DPS	Sustain
Sunday	Himeko	Jade	Aventurine

The team shown is just an example of possible Dual DPS team comps.

Sunday can also enable a double DPS team setup since he can give the main DPS extra turns, offensive buffs, and restore their Energy. This allows the main DPS to act more and activate their partner like Jade.

Sunday's Best Relics and Ornaments

All Recommended Relics and Ornaments

Relics	Rating & Merits
Sacerdos' Relived Ordeal x4	★★★★★ - Best Sacerdos is Sunday's best relic set since it gives him SPD and allows him to buff an ally's CRIT DMG even further with permanent uptime since his Skill and Ultimate are single-target.
Sacerdos' Relived Ordeal x2 Messenger Traversing Hackerspace x2	★★★★☆ - 2nd Best 2pc. Sacerdos and 2pc. Messenger is also good for Sunday since it gives him a lot of SPD to work with, but Sacerdos is still better.
Ornaments	Merits
Broken Keel	★★★★★ - Best Broken Keel is Sunday's overall best Ornament set since it gives him Effect RES and also increases the CRIT DMG of the party.
Lushaka, the Sunken Seas	★★★★☆ - 2nd Best Lushaka is also great for Sunday in hypercarry teams since it gives him Energy Regen and boosts the ATK of the first ally in the party, which is where you should place your hypercarry to gain the ATK buff.
Sprightly Vonwacq	★★★☆☆ - 3rd Best Sprightly Vonwacq is also good for Sunday since it gives him Energy Regen and gives him Advance Forward at the start of the battle, which lets him use his abilities earlier.

Relic List & Guide

Sunday's Best Light Cones

All Recommended Light Cones

A Grounded Ascent	★★★★★ - Best A Grounded Ascent is the best for Sunday since the Light Cone allows him to give DMG buffs through the Hymn effect, alleviates his Energy cost, and gives him additional SP to work with.

Earthly Escapade	★★★★☆ - Great Earthly Escapade is a great option that increases Sunday's CRIT DMG and since he also recovers SP when he uses his Skill, he can also make use of the Radiant Flame effect to provide even more crit stats for the party.

Planetary Rendezvous	★★★☆☆ - Good Planetary Rendezvous is a good Light Cone for Sunday in Imaginary teams since the Light Cone provides a DMG boost for allies with the same DMG type as the wearer.
Carve the Moon, Weave the Clouds	★★★☆☆ - Good Carve the Moon, Weave the Clouds is a good Light Cone for Sunday since it provides either an ATK, CRIT DMG, or Energy Regen buff for all allies. These are all useful buffs for either increasing the party's damage or Energy Regen.
