Light Cone
Reforged RemembranceEffect Hit Rate, ATK and stacking DEF ignore reinforce reliable Arcana application and its enemy-turn damage.
Those Many SpringsDebuff-linked damage and Effect Hit Rate support Arcana's DoT loop.
Why Does the Ocean SingIts Effect Hit Rate and enemy debuff damage improve a DoT build that reaches Arcana's EHR target.
Eyes of the PreyEffect Hit Rate eases the 120% target and its DoT bonus directly improves Arcana ticks.
This permanent four-star Warp cone is easier to obtain and superimpose than a limited signature cone.
Good Night and Sleep WellIts stacking damage bonus applies to Black Swan's DoT damage when the team supplies debuffs.
When to use it : Keep three debuffs on the target.
Relics
ATK and up to three layers of DEF ignore improve Black Swan's own Arcana and other damage; the set does not grant its DEF ignore to Kafka or Hysilens.
When to use it : Keep three DoTs on the target through Kafka and Hysilens so all three DEF-ignore stacks remain active.
Advance Forward is a speed-oriented alternative for a tuned DoT rotation.
Planar Ornaments
Its Effect Hit Rate advances the mandatory target, while the conversion supplies ATK to every Arcana tick.
Glamoth trades Pan-Cosmic's direct gearing help for a speed-gated personal damage bonus.
When to use it : Use only when the final build actually reaches a listed 135 or 160 SPD threshold without losing 120% Effect Hit Rate.
Team lineup
Hysilens supplies several DoTs, Kafka triggers them, Black Swan stacks Arcana, and Huohuo sustains while restoring Energy.
When to use it : Apply Epiphany before Kafka and Hysilens detonate DoTs so its vulnerability and no-halving window cover the burst.

- Ultimate
- Basic ATK
Black Swan turns repeated DoT events into Arcana, maintains DEF reduction and uses Epiphany to amplify a coordinated detonation window.
How to play it
- 1Open with Decadence, False Twilight when the automatic DEF reduction needs refreshing on the priority targets.
- 2Use basic attacks once DEF reduction is stable to remain Skill Point positive while adding Arcana through Viscera's Disquiet.
- 3Cast Bliss of Otherworld's Embrace immediately before the team's largest DoT detonation sequence.
Sources and methodology
Editorial recommendations are written from released game data, then cross-checked against specialist calculations. They are not copied from a single tier list.
Review method
Character kits, equipment and conditions reviewed against released Version 4.6 data. Removed Duran because Arcana does not CRIT; Prisoner now describes personal DEF ignore. Retained 120% EHR and DoT team. Cones 21066, 23055 and 23064 are Elation, while 23063 is Remembrance; their passives are incompatible with this Path. 22008 is Hunt and grants no passive outside that Path. 134 adds Basic/CRIT and does not improve Arcana; all five new cones have incompatible Paths for Nihility. Set 133 needs single-ally targeting and buffs Elation; its team CRIT bonus needs ten Certified Banger, which this kit does not provide. Prisoner's three DoTs and Epiphany window remain prerequisites rather than permanent buffs. No new damage simulation or refreshed community consensus; effect review uses the exact local 4.6 snapshot, with GitHub web access unavailable. This review includes no new damage simulation; historical community-analysis consultation dates are preserved. Methodological baseline from the previous dossier (review 4.4, reference calculations 4.0): Prydwen and Icy Veins independently converge on 120% Effect Hit Rate, Prisoner and a Kafka-led DoT core. The exact A6 conversion is min(0.60 × EHR, 72%), so 120% reaches the cap. At level 10, Arcana starts from 240% ATK + 12% per stack before the ordinary DoT DMG, DEF, RES and vulnerability multipliers; the 4.0 baseline was checked against the immutable 4.0–4.4 compare and local 4.4 effects.

Independent fan recommendations based on released data. The 120% Effect Hit Rate target caps the A6 team bonus; it does not guarantee every 65% base-chance Arcana roll against every resistance value.
