What is the best Honkai Star Rail Acheron build?
Acheron is a five-star lightning element character who treads the path of Nihility. Acheron is a seriously good damage dealer. Although she doesn't do too much damage over time, she has multiple moves that can ignore the enemy's resistances and an ultimate that has three separate instances of damage.
Here's a brief overview of our best Acheron build:
| Rarity | ★★★★★ |
| Element | Lightning |
| Path | Nihility |
| Best light cone | Along the Passing Shore |
| Light cone substitutes |
|
| Best relic set | Pioneer Diver of Dead Waters |
| Best planar ornament set | Izumo Gensei and Takama Divine Realm |

Acheron's best light cone is Along the Passing Shore, and the best relic sets to equip her with are Pioneer Diver of Dead Waters, and Izumo Gensei and Takama Divine Realm.
How to use Honkai Star Rail's Acheron
Acheron's kit is really challenging to get to grips with, especially as her ultimate is based on a stack system rather than energy. You should always run her in a Nihility-focused team to get the most out of her self-buffs, as well as the benefits she gains when her allies debuff the enemy.
Use Acheron's skill to add stacks to her ultimate charge, and then unleash her ultimate. This reduces enemies' all-type resistance and toughness, so she's able to slash through opponents regardless of their weaknesses.
What is the best light cone for Acheron?
Acheron's best light cone is her signature, Along the Passing Shore as her utility scales based on her crit rate and damage like other DPS units, rather than following the Nihility standard of debuffs and DoT.
Honkai Star Rail Silver Wolf's signature light cone, Incessant Rain, is also a decent option for Acheron thanks to its effect hit rate and crit rate buffs. Plus, as Silver Wolf has already had a banner rerun, you're more likely to have a copy of Incessant Rain lying around. In terms of four-stars, Good Night and Sleep Well is a great pick for a debuff-focused Acheron team.
If you need a crit boost and don't mind restricting your team building slightly to slow and defense-reducing Nihility units, Boundless Choreo is a reasonable four-star pick.
Here are the best HSR Acheron light cones:
| Along the Passing Shore | Increases Acheron's crit damage by 36%. When she hits an enemy, she inflicts Mirage Fizzle on them, which lasts one turn. This can trigger once on each target each time Acheron attacks. She deals 24% extra damage to targets with the Mirage Fizzle, with her ultimate doing 24% more damage on top |
| Incessant Rain | Increases Acheron's effect hit rate by 24%. When she deals damage to an enemy that currently has three or more debuffs, increases Acheron's crit rate by 12%. After Acheron uses her basic attack, skill, or ultimate, there is a 100% base chance to implant Aether Code on a random hit target that does not yet have it. Targets with Aether Code receive 12% increased damage for one turn |
| Good Night and Sleep Well | For every debuff the enemy has, Acheron's damage increases by 12%. This can stack three times and also applies to damage over time |
| Boundless Choreo | Increase Acheron's crit rate by 8%. She deals 24% more crit damage to enemies that are currently Slowed or have reduced defense |
What are the best relics for Acheron?
Acheron's best-in-slot relic set is the Pioneer Diver of Dead Waters, especially if you have her in a Nihility-based team, as the more debuffs you can dish out, the higher her damage boost will be.
However, Band of Sizzling Thunder is also a good set to boost her lightning damage and overall DPS potential, with Musketeer of Wild Wheat coming in clutch while you farm extra relics. As a skill and ultimate-focused unit, Acheron can also benefit from Scholar Lost in Erudition's crit rate and damage boosts.
Acheron's best planar ornament set by a landslide is Izumo Gensei and Takama Divine Realm. This set grants the wearer a crit rate buff if someone else on the team follows the same path, so Acheron's synergy with her fellow Nihility characters is a massive advantage here. If you haven't reached World 9 just yet, Space Sealing Station and Inert Salsotto are both good interim picks to boost her attack and crit rate.
Here are HSR Acheron's best relics:
| Pioneer Diver of Dead Waters | Two equipped: increases damage dealt to enemies with debuff by 12% Four equipped: Increases Acheron's crit rate by 4%. She deals 8/12% more crit damage to enemies with at least two/three debuffs. After she inflicts a debuff, these effects increase 100% for one turn |

What are the best team comps for Acheron?
Acheron is an interesting character, as she can attack enemies most of the time, but you can pair her with certain other very strong DPS units like Honkai Star Rail's Kafka to capitalize on their Nihility alignment.
We recommend taking one other Nihility team member with Acheron, two if you can, to activate buffs in her kit. Speaking of buffs, Pela, Silver Wolf, and Gallagher can provide debuffs to the enemies, allowing Acheron to do just a bit more damage.
Here are some examples of strong Acheron team comps:
 Acheron |
 Silver Wolf |
 Pela |
 Fu Xuan |
| Acheron |
 Kafka |
 Black Swan |
 Gallagher |
| Acheron |
 Jiaoqiu |
 Sparkle |
 Aventurine |

What are Acheron's abilities?
Here are all of Acheron's skills and abilities at level one. Keep in mind that the multipliers for each of these skills increase as you level them up.
Active skills:
| Basic attack | Trilateral Wiltcross Acheron deals lightning damage to one target, equal to 905 of her attack stat |
| Skill |
Octobolt Flash Acheron gains one point of Slashed Dream and inflicts one stack of Crimson Knot on a single target. This deals 140% of her attack as lightning damage to the single target, and then 52% of her attack as lightning damage to adjacent targets |
| Ultimate | Slashed Dream Cries in Red During her ultimate, Acheron attacks times with Rainblade, and then once with Stygian Resurge. This deals 334% of her attack as lightning damage to a single target and 270% to other targets on the field. Rainblade: This deals lightning damage equal to 21% of Acheron's attack to a single target enemy and removes three stacks of Crimson Knot. When a stack of Crimson Knot gets removed, it deals 13% of her attack as lightning damage to all enemies. For every stack removed, the damage multiplier increases, up to a maximum of 54%. Stygian Resurge: Deals lightning damage equal to 180% of her attack stat to all enemies on the field, and removes all stacks of Crimson Knot. Acheron cannot apply Crimson Knot stacks to enemies during her ultimate. |
Talent and technique:
| Talent | Atop Rainleaf Hangs Oneness When Slashed Dream reaches nine points, you can activate Acheron's ultimate. During her ultimate, enemies' toughness - regardless of weakness type - reduces by 17%, along with their all-type resistance. This lasts until the end of her ultimate. When any party member inflicts a debuff onto a target, Acheron gains a point of Slashed Dream and also applies a stack of Crimson Knot to a target. If debuffs get inflicted on multiple targets, the Crimson Knot stack goes to the target with the most stacks already. This can trigger once per ability use. After a target exits the field or gets defeated while Acheron is in the party, the Crimson Knot stacks transfer to the enemy with the next-most stacks |
| Technique | Quadrivalent Ascendance Acheron immediately attacks the enemy and gains Quadrivalent Ascendance, which deals 200% of her attack as lightning damage to all enemies, regardless of whether they are weak to it or not. After using her ultimate, Acheron gains one point of Slased Dream and inflicts one stack of Crimson Knot on a random enemy. Outside of battle, if Acheron attacks a normal enemy, she immediately defeats them without the need to enter a battle screen |
Major traces:
| A2 | Red Oni At the beginning of a battle, Acheron gains five points of Slashed Dawn and applies five stacks of Crimson Knot to a random enemy. When Slashed Dream reaches its limit, each point exceeding the limit gives her a stack of Quadrivalent Ascendance. This can stack three times |
| A4 | The Abyss When there are one or two Nihility characters - other than Acheron - in the party, the damage she deals with her basic attack, skill, and ultimate increases to 115% and 160% respectively |
| A6 | Thunder Core When Rainblade hits enemy targets with Crimson Knot stacks, Acheron's damage increases by 30%. This can stack three times and lasts for three turns. When Stygian Resurge triggers it deals additional damage six times, each dealing 25% of her attack as lightning damage to a single target at random. This counts as ultimate damage |
What are Acheron's eidolons?
For those of us lucky enough to get more than one Acheron on her banner, you can unlock her eidolons. Here are the extra talents that they provide.
Here are all of Acheron's eidolons:
| E1 | Silenced Sky Spake Sooth When dealing damage to enemies with debuffs, Acheron's crit rate increases by 18% |
| E2 | Mute Thunder in Still Tempest The number of Nihility characters required for the trace 'The Abyss' reduces by one. When Acheron's turn starts, she gains one point of Slashed Dream and inflicts one stack of Crimson Knot on the enemy that already has the most stacks |
| E3 | Frost Bites in Death Increases Acheron's ultimate level by two, up to a maximum level of 15. Also increases her basic attack level by one, up to a maximum level of ten |
| E4 | Shrined Fire or Mirrored Soul When enemy targets enter combat, Acheron inflicts them with ultimate damage vulnerability, so they take 8% more damage from ultimate moves |
| E5 | Strewn Souls on Erased Earths Increases Acheron's skill level by two, up to a maximum level of 15. Also increases her talent level by two, up to a maximum level of 15 |
| E6 | Apocalypse, the Emanator Increases all-type resistance penetration on Acheron's ultimate damage by 20%. The damage dealt by her basic attack and skill is also considered as ultimate damage. This damage can reduce enemy toughness regardless of their weakness types. When breaking their weaknesses, it triggers the lightning weakness break effect |
