Acheron is a 5-star Lightning Nihility DPS who uses a stack-based Ultimate system — no Energy bar. She fires her Ultimate when she accumulates 9 Slashed Dream stacks from debuff applications.
Her A4 trace grants a separate 160% DMG multiplier with 2 Nihility teammates — one of the most powerful damage bonuses in the game. With only 1 Nihility teammate, it drops to 115%. At E2, the requirement reduces from 2 to 1.
Her Ultimate ignores Weakness Type to reduce Toughness and shreds all enemies’ All-Type RES by 25% for the entire duration — benefiting the entire team.
Best Light Cone: Along the Passing Shore (her signature) — applies a passive debuff that generates extra Slashed Dream stacks and provides massive CRIT and DMG bonuses.
Best Relics: Pioneer Diver of Dead Waters (4-piece) + Izumo Gensei and Takama Divine Realm (Planar Ornament).
Best E0 team: Acheron / Ashveil / Mortenax Blade / Dan Heng • Permansor Terrae (S-tier 4.3). Classic strong team: Acheron / Jiaoqiu / Black Swan / Aventurine.
E1 is the first investment priority — adds 18% CRIT Rate when attacking debuffed enemies, effectively a permanent bonus in all Acheron teams.
E2 is the major build flexibility unlock — reduces Nihility requirement by 1, allowing one Harmony support slot and dramatically improving team options.
Acheron was available as a free selector in Version 4.0. Her most recent rerun was Version 3.2 (April 2025). Watch for future reruns.
She is rated T1.5 in MoC, PF, and AS as of patch 4.3 — still clears all endgame content efficiently, particularly dominant in multi-enemy Lightning-weak content.

Who Is Acheron in Honkai Star Rail?

Acheron is a 5-star Lightning character following the Path of Nihility in Honkai Star Rail. She debuted in Version 2.1 (March 2024) and was immediately recognised as one of the most powerful DPS characters in the game. As of patch 4.3, she is rated T1.5 across Memory of Chaos, Pure Fiction, and Apocalyptic Shadow — still fully clearing all endgame content efficiently, though newer characters have slightly narrowed the gap since her debut.

In the game’s lore, Acheron is the Galaxy Ranger, a mysterious swordswoman whose true name remains unknown. She wields a long blade and carries the weight of countless fallen stars. Her character arc is one of HSR’s most celebrated — a figure who appears distant and unreadable at first, revealed through the story to be deeply principled and burdened by a purpose far heavier than she lets on. Her combat animations are some of the most visually spectacular in the game, and her Ultimate is a genuine spectacle.

Mechanically, Acheron is unique in several ways. She does not use the standard Energy system — no Energy bar, no Energy Regeneration Rate. She instead uses Slashed Dream stacks, generated through debuff applications by any ally. She can break any enemy’s Toughness bar regardless of Weakness Type. And her A4 trace applies a separate damage multiplier so powerful that it effectively forces her into Nihility team compositions at E0 and E1. Her most recent rerun was Version 3.2 (April 2025).

Acheron Kit Overview – How Her Abilities Work

Acheron’s kit is built around a stack economy that rewards fast debuff application and careful Crimson Knot management before her Ultimate fires. Every ability feeds into this loop in a different way. Understanding the stack system is the key to building and playing her correctly.

Slashed Dream – The Core Resource

Slashed Dream replaces conventional Energy for Acheron. She needs 9 stacks to fire her Ultimate. Stacks are generated by:

Acheron’s own Skill: +1 stack per use
Any ally inflicting a debuff on an enemy: +1 stack per debuff application
Any enemy ability that inflicts a debuff: +1 stack
Battle start (A2 trace): +5 stacks pre-loaded
E2 passive: +1 stack at the start of Acheron’s turn

Acheron can store up to 3 overflow stacks as Quadrivalent Ascendance — excess stacks beyond 9 are not lost but saved for the next Ultimate cycle. In an active team with two Nihility debuffers applying debuffs every turn, Acheron typically fires her Ultimate once or twice per cycle. The generation rate is the primary factor governing how fast her rotation cycles.

Crimson Knot – The Damage Amplifier

Every time any debuff is applied to an enemy, that enemy receives 1 stack of Crimson Knot alongside the Slashed Dream generation. Crimson Knot stacks build up on enemies and are consumed by Acheron’s Rainblade hits during her Ultimate. Enemies with more Crimson Knot take substantially more damage from each Rainblade. The maximum is 3 stacks per enemy. Managing Crimson Knot accumulation on your primary target — particularly before Acheron’s Ultimate fires — is one of the key skill-expression elements in her rotation. More Crimson Knot on the target when the Ultimate fires equals dramatically more damage per Rainblade hit.

Basic Attack – Trilateral Slash

Deals Lightning DMG equal to 100% of Acheron’s ATK to a single target. Generates 0 Slashed Dream stacks directly but triggers the Talent’s passive if the target already has debuffs. In optimal play, Acheron rarely uses her Basic ATK — Skill spam is almost always better for stack generation. Use Basic ATK only when Skill Points are completely exhausted and no other option is available.

Skill – Octobolt Flash

Deals Blast Lightning DMG to one primary enemy and adjacent targets. Inflicts 1 stack of Crimson Knot on the primary target and grants 1 Slashed Dream stack. With her signature Light Cone, her Skill also applies the Mirage Fizzle debuff — causing the Skill to generate 2 Slashed Dream stacks instead of 1 (because the Mirage Fizzle debuff itself counts as a debuff application). This is why the signature is so transformative: it effectively doubles her Skill’s stack generation, halving the number of Skill uses needed per Ultimate cycle. Always use Skill over Basic ATK whenever Skill Points allow — stack generation is Acheron’s rotation.

Ultimate – Slashed Dream Cries in the Rain

This is one of the most powerful Ultimates in the game. When Acheron fires at 9 Slashed Dream stacks:

All enemies’ All-Type RES decreases by 25% for the duration of the Ultimate sequence.
Acheron can reduce any enemy’s Toughness regardless of Weakness Type during the entire Ultimate.
She launches 3 Rainblade hits on single targets. Each Rainblade hit deals Lightning DMG and consumes Crimson Knot stacks — dealing an additional 24% single-target DMG plus 15% AoE DMG per Crimson Knot consumed, up to 3 stacks (maximum 60% AoE bonus per hit).
After the Rainblades, she fires Stygian Resurge — a massive AoE Lightning DMG finisher that hits all enemies and additionally deals 6 individual instances of Lightning DMG equal to 25% ATK to random targets.

The combined sequence is devastating. Against a target with full 3 stacks of Crimson Knot, each Rainblade hits at maximum power. With the A2 trace’s All-Type RES shred active and the A4 trace’s 160% separate DMG multiplier, the total output per Ultimate cycle is among the highest single-cast damage values available to any DPS character.

Talent – Atop the Lonely Cliff

Whenever any ally (or enemy) inflicts a debuff on any enemy target, Acheron gains 1 Slashed Dream stack and the target enemy gains 1 Crimson Knot stack. This is the passive that makes debuff-focused teammates so essential — every Jiaoqiu Skill use, every Black Swan debuff application, every Cipher debuff, every Pela DEF reduction simultaneously feeds both Acheron’s stack generation and the Crimson Knot build-up for the next Ultimate.

A2 Trace – Red Oni

Acheron enters every battle with 5 Slashed Dream stacks already loaded. She is only 4 stacks away from her first Ultimate at the very start of every fight. In most teams, the first Ultimate fires within 2–3 turns. This pre-loading is the reason Acheron’s first-cycle damage is so reliable in endgame content.

A4 Trace – The Abyss

This is Acheron’s most defining trace — and the reason team composition is non-negotiable:

With 1 Nihility character other than Acheron: her Basic ATK, Skill, and Ultimate deal +115% of their original DMG (a 2.15x separate multiplier).
With 2 Nihility characters other than Acheron: damage increases to +160% of original DMG (a 2.6x separate multiplier).

This is a separate multiplicative layer — it multiplies on top of CRIT, ATK, and every other buff, bypassing diminishing returns entirely. The gap between 1 and 2 Nihility teammates is massive. At E0 and E1, running fewer than 2 Nihility characters means leaving an enormous portion of Acheron’s damage ceiling on the table. At E2, the requirement drops by 1, enabling one Harmony character in the team without losing the 160% bonus.

A6 Trace – Discordant Escape

When a Rainblade hit removes a Crimson Knot stack, Acheron’s DMG increases by 30% per stack removed, stacking up to 3 times and lasting 3 turns. After a full 3-Rainblade Ultimate where all hits land on enemies with 3 Crimson Knot stacks, Acheron exits with a 90% personal DMG bonus active for 3 turns — covering her next cycle of Skill spam and debuff accumulation. This is a powerful self-buffing mechanic that rewards maximizing Crimson Knot before each Ultimate fires.

Technique – Quadrivalent Ascendance

When Acheron uses her Technique in the overworld, she enters a stance that draws nearby enemies. If she enters battle from this state, she immediately deals AoE Lightning DMG to all enemies. She also stores up to 3 Quadrivalent Ascendance (overflow Slashed Dream) from the Technique — stacking these carries over to boost her in-combat generation. Always use the Technique before fights for the free pre-battle damage and overflow advantage.

Acheron Best Light Cones in HSR

Acheron follows the Path of Nihility. Only Nihility path Light Cones trigger passive effects on her. Critically: because Acheron does not use Energy, all Energy Regeneration Rate bonuses from any Light Cone are completely wasted on her — ignore ERR when evaluating her options. Her priorities are CRIT stats, DMG amplification, and crucially, passive debuff application to generate extra Slashed Dream stacks.

Along the Passing Shore (Signature – Best in Slot)

Acheron’s 5-star signature is best-in-slot by a clear margin. The 95.99% usage rate among top MoC players speaks for itself. It provides 36% CRIT DMG at S1 directly. After Acheron uses her Ultimate, CRIT DMG increases by an additional 24% for 2 turns. Most importantly: every time Acheron attacks any enemy, she applies the Mirage Fizzle debuff — a passive debuff that triggers on every Basic ATK and Skill use. Since Mirage Fizzle is a debuff application, it generates 1 additional Slashed Dream stack per use. This means Acheron’s Skill now generates 2 stacks (1 from Skill + 1 from Mirage Fizzle) instead of 1. Over a full rotation, this roughly halves the number of Skill uses needed per Ultimate cycle, dramatically improving her action economy. This is the single largest practical improvement to Acheron’s rotation speed available from any single item.

Good Night and Sleep Well (4-Star – Best Budget Option)

Acheron’s best accessible 4-star Light Cone. It provides stacking DMG bonuses — +24% per debuff on the target, up to 3 debuffs (72% total at S5). Since Acheron’s teams constantly apply multiple debuffs, the maximum bonus is reliably active almost every turn. At S5, this is rated roughly 13–14% below the signature in practice — a meaningful gap but entirely viable for clearing all endgame content. Always farm this to S5 if you do not have the signature.

Boundless Choreo (4-Star)

Provides CRIT DMG against enemies that are DEF-reduced or have their SPD slowed. Jiaoqiu and Pela both apply DEF reduction, making this conditional reliably active in common Acheron teams. A strong alternative 4-star when you need CRIT DMG and your CRIT Rate is already covered by Pioneer Diver and E1.

In the Night (5-Star Standard)

A 5-star standard banner option that provides CRIT Rate and a conditional DMG boost based on SPD. Viable if you have it from standard pulls and cannot pull Acheron’s signature — but notably weaker than the signature’s Mirage Fizzle stack generation benefit. Use as a bridge.

Acheron Best Relics in HSR

Acheron is a pure CRIT DPS. Her damage scales with ATK, CRIT Rate, and CRIT DMG — no Energy, no Break Effect, no Outgoing Healing. Every relic decision should maximize these three stats. The relic set choice is extremely important because Pioneer Diver’s 4-piece provides conditional CRIT bonuses that are permanently active in her debuff-heavy teams.

Best 4-Piece Relic Set: Pioneer Diver of Dead Waters

This is Acheron’s undisputed best relic set. The 2-piece gives 12% DMG increase against debuffed enemies — a condition that is always met in Acheron’s optimal teams. The 4-piece is the critical piece: grants +4% CRIT Rate base, and additionally increases CRIT DMG against enemies with 2 or more debuffs. When an enemy has 3+ debuffs, the CRIT DMG bonus doubles to 12% more. Since Acheron’s teams apply multiple debuffs constantly, the full 4-piece bonus is essentially always active. The combined CRIT Rate and CRIT DMG from this set significantly reduces relic pressure — you need less CRIT Rate from substats to hit your thresholds. Farm this set exclusively for Acheron.

Alternative: 2-Piece Pioneer + 2-Piece Prisoner in Deep Confinement

Running two 2-piece sets that each provide DMG-relevant bonuses is a serviceable placeholder while farming. Pioneer’s 2-piece gives DMG against debuffed enemies. Prisoner’s 2-piece gives ATK. This doubles up on offensive stats without the conditional CRIT bonuses of the full 4-piece. Use this if your 4-piece Pioneer pieces have terrible substats but you have solid Prisoner pieces available.

Best Planar Ornament: Izumo Gensei and Takama Divine Realm

Acheron’s best Planar Ornament. The 2-piece provides CRIT Rate and a DMG bonus when at least one ally shares the same path — Nihility in Acheron’s case. Since her optimal teams always include Nihility characters (Jiaoqiu, Black Swan, Pela, Mortenax Blade, Silver Wolf), this bonus is essentially always active. The CRIT Rate from the 2-piece compounds with Pioneer Diver’s 4-piece CRIT Rate bonus to significantly reduce substat CRIT Rate requirements. Farm this alongside Pioneer Diver in Simulated Universe.

Alternative Planar Ornament: Space Sealing Station

Provides ATK% and an additional ATK% bonus when SPD reaches 120 or above — easily met by Acheron. A strong alternative when you do not yet have good Izumo Gensei pieces, giving raw ATK scaling that feeds her ability multipliers. Less optimal than Izumo Gensei’s CRIT Rate in the long run but competitive at similar substat quality.

Relic Main Stats to Target

Head: HP (fixed)
Hands: ATK (fixed)
Body: CRIT Rate (priority — aim for 70%+ in-combat; Pioneer + Izumo + E1 help significantly)
Feet: SPD (134+ for better action economy and faster Slashed Dream generation) or ATK% (if relying on action advance from E2 Harmony teammates). Most players run SPD boots.
Planar Sphere: Lightning DMG Bonus — directly scales all her ability multipliers.
Link Rope: ATK% — since Acheron has no Energy system, Energy Regeneration Rate is completely useless. Always run ATK%.

Key Substat Priority

CRIT Rate until reaching 70%+ in-combat (with Pioneer 4-piece, Izumo, and E1 all contributing, you may need less from substats than expected). CRIT DMG is the top offensive substat after CRIT Rate is covered — push toward 160%+ and beyond. ATK% is the third priority. SPD substats help reach the 134 breakpoint if not using SPD boots. Never roll for Break Effect or Effect Hit Rate — both are irrelevant to Acheron’s damage.

Stat Targets

CRIT Rate: 70%+ in-combat (with all team buffs active)
CRIT DMG: 160%+ (higher is always better)
ATK: 2,400–2,800+
SPD: 134+ (for standard builds) or lower if relying on action advance

Acheron Best Teams in HSR 4.3

Team building around Acheron is dominated by one rule at E0–E1: you need 2 Nihility characters other than Acheron to activate the full 160% A4 separate DMG multiplier. Dropping to 1 Nihility teammate reduces the multiplier to 115% — a loss of roughly 35% of her total damage output from that layer alone. This is not optional at E0. Only E2 changes this equation.

Current Best Team (4.3): Acheron / Ashveil / Mortenax Blade / Dan Heng • Permansor Terrae

The S-tier Acheron team for patch 4.3 according to current community tier data. Ashveil is a new sub-DPS character who brings Vulnerability debuffs, DEF shred, and taunt utility — both Ashveil and Mortenax Blade count as Nihility characters, satisfying the E0 requirement. Mortenax Blade is a new 4.3 Nihility character whose Bounded Field spreads Balefire Bind debuffs whenever allies attack, generating Slashed Dream stacks constantly for Acheron even between her own turns. His passive debuff spread dramatically accelerates Acheron’s stack generation rate. Dan Heng • Permansor Terrae handles sustain through shields and ATK buffs. This team is especially dominant in Apocalyptic Shadow boss content.

Classic Premium Team: Acheron / Jiaoqiu / Black Swan / Aventurine

Jiaoqiu is considered one of Acheron’s best traditional Nihility partners. He applies Ashen Roast debuffs that stack enemy damage vulnerability while simultaneously generating Slashed Dream stacks. His debuff penetration is high and reliable. Black Swan applies stacking Arcana DoT debuffs that generate Crimson Knot and Slashed Dream simultaneously — and each individual Arcana stack triggers further Talent activations. Aventurine provides shields and the Unnerved CRIT DMG debuff (itself another Crimson Knot and Slashed Dream trigger). This team was Acheron’s gold standard for a long time and remains highly viable in 4.3.

Silver Standard Team: Acheron / Jiaoqiu / Cipher / Dan Heng • Permansor Terrae

A strong and accessible alternative to the Black Swan team. Jiaoqiu debuffs on every action. Cipher applies consistent Nihility debuffs that feed Slashed Dream generation. Dan Heng • Permansor Terrae handles shields and ATK buffs. This team is reliable in all endgame content and is more accessible than running both Black Swan and Jiaoqiu.

E2 Acheron Team (Harmony Slot Unlocked): Acheron / Jiaoqiu / Sunday / Dan Heng • Permansor Terrae

At E2, Acheron only needs 1 Nihility teammate to maintain the full 160% A4 multiplier. This unlocks a Harmony character slot. Jiaoqiu alone handles the Nihility requirement. Sunday provides 100% Action Advance, CRIT DMG buffs, and Energy restoration — dramatically accelerating how fast Acheron acts and therefore how fast she accumulates Slashed Dream stacks through Skill spam. This is widely considered the best E2 Acheron team and one of the reasons E2 is Acheron’s recommended power spike target. Sunday’s action advance effectively gives Acheron extra turns per cycle, compressing the rotation timeline significantly.

Accessible Budget Team: Acheron / Pela / Silver Wolf / Gallagher

Pela is a free-to-play Nihility character who applies DEF reduction debuffs on every Skill use — feeding both Slashed Dream and Crimson Knot consistently. Silver Wolf applies a unique permanent Weakness debuff plus additional debuffs that generate stacks every action. Gallagher handles sustain efficiently with low SP cost. This team satisfies the 2-Nihility requirement with two 4-star accessible characters and a healer, making it the most budget-friendly path to clearing MoC with Acheron.

Notable Nihility Partner Notes

Jiaoqiu — Best traditional Nihility support. Ashen Roast stacks provide vulnerability debuffs that simultaneously generate stacks and amplify Ultimate damage.
Black Swan — Arcana DoT chains trigger multiple simultaneous Talent activations. Works particularly well in Pure Fiction.
Pela — Best free 4-star option. DEF reduction on Skill + Ultimate gives reliable stack generation every turn.
Silver Wolf — Permanent Weakness implant plus multi-debuff applications. Unique value for making any enemy Weak to Lightning.
Kafka — Good for Pure Fiction AoE content. Each DoT triggers count as debuff applications, generating stacks off-turn.

Acheron Trace Priority

Acheron is a DPS character, so her trace priorities focus on the abilities that govern her damage output and Ultimate cycle speed.

Ultimate – First and highest priority. Her Ultimate contains virtually all of her major damage multipliers — the Rainblade hit multipliers, the Crimson Knot bonus damage per stack removed, and the Stygian Resurge AoE finisher. Every level meaningfully increases the damage of all these components. Max this first.
Skill – Second. Higher Skill level increases the Blast DMG multiplier and the Crimson Knot stack applied per use. Since Skill is used constantly between Ultimates, every level compounds across the entire rotation.
Major Traces — Unlock all three as priority. A2 (Red Oni — 5 starting Slashed Dream stacks) is the reason her first Ultimate fires so fast. A4 (The Abyss — 115/160% separate DMG multiplier) is non-negotiable and arguably the single most important passive on any character in the game. A6 (Discordant Escape — 30% DMG per Crimson Knot removed, up to 90%) is the self-buffing mechanic that sustains her power after each Ultimate. All three must be unlocked as soon as ascension allows.
Talent – Third. The Talent governs Slashed Dream generation from debuff applications. While the raw stack generation is more tied to team composition than Talent level, higher Talent level increases the damage multipliers on some Talent-related effects.
Basic Attack – Last. Rarely used in optimised play. Level minimally.

Acheron Eidolons – Which Ones Are Worth It?

Acheron performs very well at E0, but her Eidolons follow a clear power progression with two standout investments.

E1 – Best Value Eidolon (First Investment Priority)

E1 grants Acheron a +18% CRIT Rate bonus when dealing DMG to debuffed enemies. Since Acheron’s optimal teams always have debuffs on every enemy at all times, this is effectively a permanent +18% CRIT Rate. This dramatically reduces relic pressure — you need roughly 18% less CRIT Rate from substats, relics, and Planar Ornaments to hit the 70%+ threshold. In practice, E1 allows Acheron to invest those freed-up substat rolls entirely into CRIT DMG instead, significantly boosting total damage output. Most community guides rate E1 as the single best return on investment for any Acheron Eidolon. Pull this before considering the signature LC.

E2 – Major Build Flexibility Unlock (Recommended Stop Point)

E2 reduces the number of Nihility characters required for The Abyss to achieve its highest effect by 1. At E2, Acheron needs only 1 Nihility teammate to maintain the full 160% separate DMG multiplier — opening the entire second slot for Harmony characters like Sunday or Sparkle. Additionally, E2 automatically generates 1 Slashed Dream stack at the start of Acheron’s turn, smoothing her rotation and reducing the number of Skill casts needed per cycle. The combined effect — expanded team building options and faster stack generation — is widely considered Acheron’s true power breakpoint. E2 is the recommended stopping point for players invested in Acheron long-term.

E4 – Rotation Comfort

Acheron’s Skill no longer costs Skill Points. Additionally, each Rainblade hit during her Ultimate deals an extra Lightning DMG instance equal to 50% of her ATK. The SP-free Skill removes team-building pressure entirely — she is fully SP-positive at E4, making it much easier to pair with SP-hungry Harmony supports. The extra Rainblade DMG is a meaningful damage boost. Valuable but expensive to reach.

E6 – Maximum Investment

E6 massively increases the Additional DMG from Stygian Resurge and provides significant further multiplier boosts. A transformative power spike at very high investment. E2 remains the practical target for the vast majority of players.

Acheron Rotation Guide – How to Play Her

Acheron’s rotation is straightforward in principle and slightly nuanced in execution — particularly around timing the Ultimate for maximum Crimson Knot value.

Battle Start

Use Acheron’s Technique before entering a fight to gain pre-combat DMG and store Quadrivalent Ascendance overflow. Acheron enters with 5 Slashed Dream stacks from A2, leaving only 4 needed before the first Ultimate. In most teams with two active debuffers, the first Ultimate fires within 2–3 turns — often on Acheron’s very first action if debuffs have already applied from allies acting first.

Pre-Ultimate Stack Building

Use Skill every turn to generate Slashed Dream stacks and apply Crimson Knot to the primary target. Watch the Crimson Knot counter on your target — try to have all 3 stacks on the primary enemy before your Ultimate fires for maximum Rainblade damage. With two Nihility teammates applying debuffs on their turns, Slashed Dream stacks also build passively between Acheron’s actions. The stack counter reaches 9 fast in active teams.

Firing the Ultimate

When Slashed Dream hits 9, fire the Ultimate immediately in most cases. If Crimson Knot is not at 3 stacks on the primary target, consider using one more Skill first — the extra Crimson Knot stack is often worth the delay. Let the rotation play out: 3 Rainblades hit the primary target, consuming Crimson Knot for AoE explosions, then Stygian Resurge sweeps all enemies. After the Ultimate, Acheron has A6’s 90% DMG buff active for 3 turns — her next Skill spam phase benefits from the full self-buff stack.

Managing Overflow

Acheron can store up to 3 overflow stacks (Quadrivalent Ascendance) beyond the 9 needed for her Ultimate. Do not let this cap out unnecessarily — if you are sitting at 9 stacks and have debuffs still applying, fire the Ultimate before overflow is wasted. Timing the Ultimate to immediately precede a heavy debuff application window from Jiaoqiu or Black Swan maximises Crimson Knot at the moment of firing.

Should You Pull Acheron in HSR 4.3?

Yes — Acheron remains one of the safest long-term DPS investments in the game. She is rated T1.5 in patch 4.3, which means she is still clearing all endgame content efficiently with proper investment — she just requires more specific team building than the newest meta DPS characters at E0. The Nihility requirement is a genuine constraint, but Jiaoqiu, Pela, Silver Wolf, Cipher, and now Mortenax Blade give players multiple accessible ways to satisfy it.

Her strengths are significant and durable: she ignores Weakness Types entirely, her Ultimate applies a universal All-Type RES shred that benefits the whole team, her A4 separate multiplier scales independently of all other buffs, and she does not use Energy (making ERR irrelevant and freeing up relic slots other DPS cannot afford). Her Slashed Dream system also means she fires her Ultimate frequently — often twice per cycle in fast teams — delivering consistent, recurring burst damage rather than a slow wind-up.

The honest limitation in 4.3: she is somewhat power-crept relative to the newest Remembrance and Amphoreus-archetype DPS characters. Players without Jiaoqiu face a meaningful challenge satisfying the 2-Nihility requirement efficiently at E0. And the new 4.3 team pairing (Ashveil + Mortenax Blade) requires two specific new characters who were not available when Acheron debuted.

Investment priority: E1 first (permanent +18% CRIT Rate), then signature LC, then E2 for full flexibility. E2 is the practical ceiling for most dedicated Acheron players — it transforms her team building from restricted to open-ended. For teams to pair with Acheron, see our guides for Jiaoqiu, Black Swan, Pela, Silver Wolf, Aventurine, Dan Heng • Permansor Terrae, and Sunday (for E2 builds). For other top-tier DPS alternatives, see our guides for Phainon, Castorice, and Anaxa.
