Characters and equipment that use this material

Quantum★★★★★

Silver Wolf

Released Jun 7, 2023Quantum Nihility debuffer and Weakness enablerGuide

Silver Wolf’s Skill can implant an on-field ally’s Type as a Weakness on one enemy and reduce that Type’s RES, while her Ultimate reduces DEF. Her Technique deals Quantum damage to all enemies and reduces their Toughness regardless of Weakness Type after combat begins. The supplied ability data contains versions with different chances, durations, target scopes, and Talent effects; use the applicable version’s details.

Physical★★★★

Natasha

Released Apr 26, 2023Single-target and teamwide healerGuide

Natasha is a Physical Abundance character for teams that need both targeted healing and an all-ally heal. Her Skill heals one ally immediately and over time; her Ultimate restores HP to the whole team. She is most useful when those two healing patterns answer the fight’s damage pressure.

Physical★★★★★

Clara

Released Apr 26, 2023Counter-based physical attacker who draws enemy attacksGuide

Clara is a Physical Destruction character whose damage and protection interact with enemies attacking her. Her Talent reduces damage from enemy attacks and retaliates against attackers; her Ultimate reduces damage further, draws enemy attention, and enhances counters. Consider her when a fight’s enemy actions can feed those counterattacks.

Wind★★★★

Sampo

Released Apr 26, 2023Wind damage-over-time attacker and DoT damage amplifierGuide

Sampo is a Wind Nihility character whose attacks can inflict stackable Wind Shear. His Skill makes multiple hits against random enemies, and his Ultimate can increase enemies’ DoT taken.

Fire★★★★

Hook

Released Apr 26, 2023Fire Destruction character who deals single-target damage, applies Burn, and gains extra damage and Energy against Burned enemies.Guide

Use Hook when you want a straightforward Fire attacker whose Skill can set up Burn and whose Talent rewards attacking Burned targets. Her Ultimate enhances her next Skill into an attack that also hits adjacent enemies, giving her a limited way to broaden her damage beyond one target.

Physical★★★★

Luka

Released Jul 19, 2023Physical Bleed damage dealer with a damage-taken debuffGuide

Luka is a Physical Nihility character who applies Bleed, increases one enemy’s damage taken with his Ultimate, and builds Fighting Will to power an enhanced Basic ATK. Consider him when you want single-target pressure tied to Bleed and can make use of his extra Bleed damage trigger.

Nihility★★★

Void

Introduced in v1.0Nihility Light Cone that temporarily increases the wearer’s Effect Hit Rate at battle start.Guide

Void raises its wearer’s Effect Hit Rate by 20%–40% for three turns at the start of battle. Its value depends on whether the wearer benefits from the boost during that opening window.

Nihility★★★

Loop

Introduced in v1.0Nihility Light Cone that increases the wearer’s damage against Slowed enemies.Guide

Loop increases the wearer’s damage to Slowed enemies by 24%–48%, depending on superimposition. The bonus is conditional on the enemy currently being Slowed.

The Hunt★★★

Adversarial

Introduced in v1.0The Hunt Light ConeGuide

Adversarial grants a short SPD increase when its wearer defeats an enemy. It is most useful when the wearer can secure frequent defeats and the two-turn speed boost helps with the next actions; it gives no stated benefit before a defeat occurs.

Erudition★★★★

The Birth of the Self

Introduced in v1.0Follow-Up Attack Light ConeGuide

The Birth of the Self increases the Erudition wearer's Follow-Up ATK damage, with an additional increase against enemies at or below 50% HP. Consider it for a wearer who deals a meaningful share of damage through Follow-Up ATKs.

Nihility★★★★

Eyes of the Prey

Introduced in v1.0Effect Hit Rate and DoT Light ConeGuide

Eyes of the Prey increases the Nihility wearer's Effect Hit Rate and DoT. Consider it for a wearer whose effects benefit from Effect Hit Rate and who deals damage through DoT.

Erudition★★★★

Make the World Clamor

Introduced in v1.0Ultimate-focused Erudition Light ConeGuide

Make the World Clamor grants Energy immediately when battle begins and increases the wearer’s Ultimate damage. Consider it for an Erudition wearer whose damage plan makes meaningful use of their Ultimate, particularly when the opening Energy is useful.

Preservation★★★★

We Are Wildfire

Introduced in v1.0Opening damage reduction and healing Light ConeGuide

We Are Wildfire reduces damage taken by all allies for five turns at battle start and immediately heals each ally for a fraction of their missing HP. Consider it when an opening defensive boost and team-wide recovery are useful, while accounting for its fixed opening timing.

The Hunt★★★★

River Flows in Spring

Introduced in v1.0Hunt damage Light ConeGuide

River Flows in Spring grants its wearer Speed and damage after entering battle. If the wearer is hit, both bonuses disappear until after the end of the wearer's next turn.

Destruction★★★★★

Something Irreplaceable

Introduced in v1.0The Destruction damage and self-healing Light ConeGuide
