WHERE IT FITS

Characters and equipment that use this material

Black SwanWind★★★★★

Black Swan

Released Feb 6, 2024Wind Nihility damage dealer who builds Arcana through damage-over-time applicationsGuide

Black Swan applies Arcana, a stacking Wind damage-over-time effect, and increases its pressure through enemy turns, allied DoT applications, and her Ultimate’s Epiphany state. Consider her when the team can apply DoT repeatedly and fights allow enemies to take turns, since Arcana’s main damage and additional effects resolve at the start of enemy turns.

CipherQuantum★★★★★

Cipher

Released Jun 11, 2025Quantum Nihility character who weakens enemies, attacks a marked Patron with follow-ups, and converts eligible ally damage against that target into tally-based Ultimate damage.Guide

Cipher suits combat where allies can repeatedly attack a shared target. Her Talent marks a Patron, follows up when an ally attacks it, and tallies part of eligible ally damage. Her Skill weakens the primary target and adjacent enemies while boosting her ATK; her Ultimate uses the tally and clears it. Her Technique also offers overworld mobility and potential Consumable gains.

HysilensPhysical★★★★★

Hysilens

Released Aug 13, 2025Physical Nihility character who applies DoT states and creates a Zone that adds Physical DoT when enemies take DoT. Consider her when you want area debuffs and damage linked to enemy DoT.Guide

Hysilens’s Skill damages all enemies and has a base chance to increase their damage taken. Her Ultimate creates a temporary Zone that reduces enemy ATK and DEF; while it lasts, enemy DoT can trigger additional Physical DoT. Her Talent can inflict Wind Shear, Bleed, Burn, or Shock when allies attack.

Holiday Thermae EscapadeNihility★★★★

Holiday Thermae Escapade

Introduced in v3.4Nihility Light Cone for a wearer who attacks often and can apply a damage taken increase to attacked enemies.Guide

Holiday Thermae Escapade increases the wearer's DMG dealt and gives each attack a guaranteed base chance to inflict Vulnerability on the attacked target. Consider it when the wearer attacks and the target can benefit from increased damage taken; the Vulnerability effect lasts 2 turns and does not stack with effects of the same type.
