Recommended build
Light Cone
Reforged RemembranceEffect Hit Rate, ATK and stacking DEF ignore reinforce both reliable Arcana application and its enemy-turn damage.
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 WellGood Night and Sleep Well converts every debuff on the target into more personal damage, including damage over time.
When to use it : Use in teams that reliably keep three debuffs on the target.
Relics
ATK and up to three layers of DEF ignore multiply the team's repeated DoT events.
When to use it : Keep three DoTs on the target through Kafka and Hysilens so all three DEF-ignore stacks remain active.
Two-piece Musketeer of Wild Wheat plus two-piece Messenger Traversing Hackerspace is a transition mix: Increases ATK by 12%. Increases SPD by 6%.
It reuses strong pieces from two sets while a complete four-piece configuration with equivalent main stats and substats is still being farmed.
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.

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
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.
