WHERE IT FITS

Characters and equipment that use this material

Imaginary★★★★★

Welt

Released Apr 26, 2023Imaginary Nihility character whose listed abilities deal damage and can Slow or delay enemy actions.Guide

Welt’s listed abilities pair Imaginary damage with enemy control. His Skill can Slow enemies, his Ultimate can Imprison them, and his Talent adds damage when he hits an already Slowed enemy. The ability data contains two distinct kits; their hit counts, Ultimate effects, and trace bonuses should be understood as alternate versions rather than simultaneous abilities.

Thunder★★★★★

Kafka

Released Jul 19, 2023Lightning Nihility character whose listed abilities apply Shock and trigger damage from current DoTs. Kafka can deal Lightning damage to one or multiple enemies, and her listed Skill and Ultimate descriptions include effects that trigger DoT damage. Some ability records conflict, so their disputed mechanics cannot be treated as settled.Guide

Kafka’s records describe Shock as a Lightning DoT that damages affected enemies at the beginning of their turns. The records disagree on the target coverage and mechanics of her Skill and Ultimate, and on the Talent’s trigger condition and follow-up count. Those conflicts prevent a single settled account of those details.

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.
