Sunday

Harmony support that advances an ally and their summon while supplying CRIT buffs and Energy

Released Dec 4, 2024

Sunday boosts one ally’s damage and CRIT Rate, lets that ally and its summon act immediately, and uses his Ultimate to restore Energy and grant a CRIT DMG buff. Consider him for a damage dealer with a summon or for a non-Harmony ally who benefits from repeated action access. His Skill’s immediate action effect does not work on Harmony characters.

Sunday GUIDE

Understand Sunday

Useful when…

Advancing a non-Harmony ally and its summon together
Restoring a selected ally’s Energy and raising its CRIT DMG
Boosting an ally’s damage, CRIT Rate, and action access with one Skill

What does his Skill provide?

Benison of Paper and Rites makes one ally and its summon immediately take action, increases that ally’s damage, and gives an additional damage increase if the target has a summon. The listed buff lasts two turns. Using the Skill on The Beatified restores one Skill Point. The Skill also raises the target’s CRIT Rate for three turns. Sunday cannot trigger the immediate action effect when he uses the Skill on a Harmony character, so target selection matters. His Technique increases the damage dealt by the first ability he uses on an ally in the next battle for two turns.

How does the Ultimate support an ally?

Ode to Caress and Cicatrix restores Energy equal to 20% of the target’s Max Energy, then makes the ally and its summon The Beatified. The status increases their CRIT DMG based on Sunday’s CRIT DMG plus a flat amount. Its duration decreases at the start of Sunday’s turns, lasts three turns total, and applies only to the most recent Ultimate target, excluding Sunday. If Sunday is knocked down, the status is dispelled. This makes the Ultimate a focused support tool rather than a partywide buff.

Which traces are worth focusing on?

The Skill carries his action advance, damage boost, and CRIT Rate increase, so prioritize it when he is being used as an action support. The Ultimate is important when Energy recovery and the Beatified CRIT DMG buff are part of the plan. His Talent strengthens the Skill’s CRIT Rate effect. The listed bonus traces include CRIT DMG and Effect RES. His Basic Attack is a single-target hit. High trace levels require more materials, including a weekly material at the listed final example step, so focus on the support abilities rather than spending broadly at once.

What can interrupt the plan?

The immediate action effect fails on Harmony-path targets, even though the Skill can still apply its other described effects. The Ultimate’s Beatified status is confined to the latest ally target and disappears if Sunday is knocked down. A summon receives the linked support alongside its character, but the skill does not say that arbitrary additional allies are advanced. The listed comparison candidates have different Paths, but their supplied comparison records do not establish equivalent action-advance or summon support.

Limitations and tradeoffs

The Skill’s immediate action effect does not trigger on Harmony characters.
The Ultimate supports only its most recent ally target and is dispelled if Sunday is knocked down.
His main buffs are targeted rather than partywide.

Common mistakes to avoid

Expecting the Skill to advance a Harmony-path ally’s action.
Assuming the Ultimate buff applies to multiple allies at once.
Forgetting the Beatified effect is dispelled if Sunday is knocked down.
