What Combat Type is Sunday?

Sunday is a 5-star Imaginary character on the Path of Harmony, from Penacony, released in version 2.7.

What stat does Sunday scale on?

Sunday's abilities multiply ATK. That is read from the scaling rows on the Skill and Ultimate, not from the ability description, so it reflects what the game actually multiplies rather than what the text mentions.

What is the best Light Cone for Sunday?

Flowing Nightglow is the closest fit on the data: it is a 5-star Harmony Light Cone with 635 base ATK at level 80, and its passive acts on ATK. Carve the Moon, Weave the Clouds is the best 4-star alternative.

Which relic set should Sunday use?

Wastelander of Banditry Desert. Its 2-piece bonus is: Increases Imaginary DMG by 10%. Its 4-piece bonus is: When dealing DMG to debuffed enemy targets, the wearer has their CRIT Rate increased by 10%. And when they deal DMG to Imprisoned enemy targets, their CRIT DMG increases by 20%.

Which Planar Ornament should Sunday use?

Sprightly Vonwacq. Its 2-piece bonus is: Increases the wearer's Energy Regeneration Rate by 5%. When the wearer's SPD reaches 120 or higher, the wearer's action is Advanced Forward by 40% immediately upon entering battle. Planar Ornaments have no 4-piece bonus; the sphere and the rope are the whole set.

How much does it cost to max Sunday's traces?

Taking one ability from level 1 to 10 costs 652,500 Credits and 2× Tracks of Destiny among other materials. The Materials tab lists every item per level.

What does Sunday E1 do?

Millennium's Quietus: 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).
