Good for Plunging Attack DMG Dealers

Both the 2-set and 4-set of Long Night's Oath provide a significant boost to Plunging Attack DMG, making it a great option for characters whose primary source of DMG is Plunging Attacks.

This set is exceptionally useful for Varesa, who can easily trigger the 4-set effects due to her kit's combination of Elemental Skill, Charged Attacks, and Plunging Attacks.

Long Night's Oath Rating

Rank

Long Night's Oath comes out as the new Best-in-Slot artifact set for Plunge DPS characters, setting itself up as S-tier due to the relevance of Plunge teams with the release of Varesa.

However, it falls short of reaching SS-tier due to it being locked to Plunge characters or a dedicated Plunge support like Xianyun.

Long Night's Oath Best Characters

Best Characters and Explanation

Character	Explanation
Varesa	• Varesa's kit focuses on Plunging Attacks and can increase her damage efficiently with this artifact.
Xiao	• The DMG bonus can increase Xiao's plunging attack damage during his Elemental Burst.
Gaming	• Gaming's main source of damage is also Plunging Attacks. However, because Gaming's Elemental Skill provides no damage, obtaining the 4-set complete stack may be difficult.
Xianyun for other characters like Diluc	• When Xianyun is in the party and your focus is on the character's Plunging Attacks, Long Night's Oath becomes their best-in-slot artifact set.
