Light Cone
Along the Passing ShoreCRIT DMG, unconditional damage and Acheron's own debuff application improve both Ultimate damage and charging consistency.
When to use it : Attack an enemy without Mirage Fizzle so the cone creates a separate debuff event and one additional Slashed Dream stack.
Good Night and Sleep WellA multiplicative damage bonus scales Acheron's Ultimate once the team supplies enough debuffs, though the cone does not create a charge itself.
This permanent four-star Warp cone avoids a limited signature and can be superimposed from ordinary pulls.
When to use it : Maintain at least three debuffs through Jiaoqiu and Pela to receive all three damage stacks.
Boundless ChoreoBoundless Choreo adds CRIT Rate and raises CRIT DMG against Slowed or DEF-reduced targets.
When to use it : Use only when the team reliably Slows enemies or reduces their DEF.
Relics
Debuffed targets activate damage and CRIT bonuses for the multi-hit Ultimate where most of her output sits.
When to use it : Apply a debuff before the Ultimate sequence and use Acheron's own debuff to double the four-piece CRIT bonuses.
Quantum-set DEF ignore can outperform generic bonuses when its weakness condition is guaranteed.
When to use it : Use only against Quantum-weak enemies or with reliable Quantum Weakness implantation; otherwise its second DEF-ignore layer is absent.
Planar Ornaments
ATK and conditional CRIT Rate match the Nihility teammates already required by Acheron's E0 damage trace.
When to use it : Keep at least one other Nihility ally in the team so Izumo's entering-battle CRIT Rate activates.
Inert Salsotto is a ranked alternative with this two-piece effect: Increases the wearer's CRIT Rate by 8%. When the wearer's current CRIT Rate reaches 50% or higher, the DMG dealt by the wearer's Ultimate and Follow-Up ATK increases by 15%.
When to use it : Reach 50% CRIT Rate to activate the Ultimate and Follow-Up ATK bonus.
Team lineup
Jiaoqiu and Pela apply frequent debuffs and shred defenses, while Aventurine sustains and adds Unnerved for another charge event.
When to use it : At E0, keep both Jiaoqiu and Pela in the lineup so The Abyss reaches its two-Nihility multiplier and debuffs arrive between Acheron turns.
Trace priority
- Ultimate
- Skill
- Talent
- Basic ATK
Acheron gains Slashed Dream whenever allies apply debuffs, then spends nine stacks on a multi-stage Ultimate that ignores Weakness Types.
How to play it
- 1Let Jiaoqiu and Pela use separate debuffing abilities before Acheron acts: each grants one Slashed Dream charge per eligible ability use, even when that ability applies multiple debuffs or hits multiple targets.
- 2Use Octobolt Flash on the priority target to add Slashed Dream and concentrate Crimson Knot there.
- 3Cast Slashed Dream Cries in Red at nine stacks after defense reduction and vulnerability are active.
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 agree that Acheron's E0 baseline uses two other Nihility characters, frequent separate debuffing abilities and an Ultimate-first CRIT build. The debuff trigger grants one Slashed Dream charge per eligible ability use, even when that ability applies multiple debuffs or hits multiple targets; Mirage Fizzle can make an attack eligible, but cannot multiply that once-per-use trigger. The 4.0 baseline was compared with the immutable 4.0–4.4 delta and exact local 4.4 effects before setting the in-combat CRIT targets.

Independent fan recommendations based on released data. The team assumes E0 Acheron: replacing one Nihility ally before E2 lowers The Abyss multiplier and usually slows Slashed Dream generation.
