Acheron Guide and Best Builds

Introductions

Acheron is a 5-Star Lightning Character following the Path of Nihility. Acheron is an excellent DPS who excels at dealing AoE DMG to enemies through heavy use of her Ultimate, while also being able to self-buff through team synergies with Nihility allies.
Our Acheron Build Guide will show you the best Light Cones, Relics, and Team Compositions to help you build the best Acheron.

Acheron's Best Light Cone

Listed below are the Light Cones we recommend for Acheron.

Along the Passing Shore

Increases the wearer's CRIT DMG by 36.0 / 42.0 / 48.0 / 54.0 / 60.0%. When the wearer hits an enemy target, inflicts Mirage Fizzle on the enemy, lasting for 1 turn. Each time the wearer attacks, this effect can only trigger 1 time on each target. The wearer deals 24.0 / 28.0 / 32.0 / 36.0 / 40.0% increased DMG to targets afflicted with Mirage Fizzle, and the DMG dealt by Ultimate additionally increases by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%.

Sources: Event Warp (limited)

As Acheron's signature Light Cone, this is currently considered her best option through the sheer amount of DMG it produces. Her signature weapon allows her to apply an extra debuff, increasing the amount of Slashed Dream produced, which ultimately enhances the amount of DMG her Ultimate deals.

Incessant Rain

Increases the wearer's Effect Hit Rate by 24.0 / 28.0 / 32.0 / 36.0 / 40.0%. When the wearer deals DMG to an enemy that currently has 3 or more debuffs, increases the wearer's CRIT Rate by 12.0 / 14.0 / 16.0 / 18.0 / 20.0%. After the wearer uses their Basic ATK, 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 12.0 / 14.0 / 16.0 / 18.0 / 20.0% increased DMG for 1 turn.

Sources: Event Warp (limited)

Another great 5-Star Light Cone for Acheron after her signature weapon. Incessant Rain provides a Vulnerability debuff on hit, allowing her to deal increased DMG, but it's a limited option for Acheron in the sense that the debuff is applied only after the attack and only affects one target, making it a slightly more restrictive option.

Holiday Thermae Escapade

Increases the wearer's DMG dealt by 16.0 / 20.0 / 24.0 / 28.0 / 32.0%. After the wearer attacks, there is a 100% base chance to inflict the attacked target with Vulnerability, increasing the DMG they receive by 10.0 / 11.5 / 13.0 / 14.5 / 16.0% for 2 turn(s). Effects of the same type cannot stack.

Sources: Nameless Glory

This 4-Star Light Cone is a good option, as it increases overall DMG dealt as well as inflicting Vulnerability on an enemy, which helps Acheron stack Slashed Dream.

Good Night and Sleep Well

For every debuff the target enemy has, the DMG dealt by the wearer increases by 12.0 / 15.0 / 18.0 / 21.0 / 24.0%, stacking up to 3 time(s). This effect also applies to DoT.

Sources: Stellar Warp

This 4-Star Light Cone is a good option, as it increases overall DMG dealt as well as inflicting Vulnerability on an enemy, which helps Acheron stack Slashed Dream.

Boundless Choreo

Increase the wearer's CRIT Rate by 8.0 / 10.0 / 12.0 / 14.0 / 16.0%. The wearer deals 24.0 / 30.0 / 36.0 / 42.0 / 48.0% more CRIT DMG to enemies that are currently Slowed or have reduced DEF.

Best Relics and Planar Ornaments for Acheron

Best Relics for Acheron

These are the best Relic sets for Acheron.

Pioneer Diver of Dead Waters

2-Piece Set: Increases DMG dealt to enemies with debuffs by 12.0%.

4-Piece Set: Increases CRIT Rate by 4.0%. The wearer deals 8.0%/12.0% increased CRIT DMG to enemies with at least 2/3 debuffs. After the wearer inflicts a debuff on enemy targets, the aforementioned effects increase by 100%, lasting for 1 turn(s).

This 4-piece set is great for Acheron as it increases her overall DMG as well as her Crit Rate and Crit DMG when enemies have been inflicted with a debuff. This relic set works perfectly with her as Acheron wants lots of debuffs.

Poet of Mourning Collapse

2-Piece Set: Increases Quantum DMG by 10.0%.

4-Piece Set: Decreases the wearer's SPD by 8.0%. Before entering battle, if the wearer's SPD is lower than 110/95, increases the wearer's CRIT Rate by 20.0%/32.0%. This effect applies to the wearer's memosprite at the same time.

This 4-piece set is another strong option for Acheron when she is in teams that want lower SPD. This set enhances Crit Rate and decreases the wearer's SPD upon entering a battle which works perfectly for Acheron to enhance her DMG output even more. If Acheron has a higher SPD than 100, it isn't recommended to use this over the first set.

Best Planar Ornaments

Izumo Gensei and Takama Divine Realm

2-Piece Set: Increases the wearer's ATK by 12.0%. When entering battle, if at least one teammate follows the same Path as the wearer, then the wearer's CRIT Rate increases by 12.0%.

This is a great choice for Acheron, as it increases her ATK as well as Crit Rate if another ally follows the same Path. This works well as Acheron intends to have at least 2 other Nihility allies in her team during a battle.

Inert Salsotto

2-Piece Set: Increases the wearer's CRIT Rate by 8.0%. When the wearer's current CRIT Rate reaches 50.0% or higher, the DMG dealt by the wearer's Ultimate and Follow-Up ATK increases by 15.0%.

Another great option for Acheron that increases both her CRIT Rate as well as her follow-up and ultimate DMG.

Acheron Build Comments

Character Synergy Main DPS vs Sub DPS

Character Synergy

When building a team for Acheron you should prioritise characters from the Path of Nihility. This is because her A4 ability grants a significant separate DMG multiplier when paired with one or two other Nihility allies. In addition, Nihility characters excel at applying debuffs which are essential for generating Slashed Dream stacks and applying Crimson Knot, both of which directly impact Acheron's Ultimate DMG. Since her Ultimate ignores Weakness Types, team building should focus on consistent debuff application rather than elemental coverage.

Main DPS vs Sub DPS

Acheron is a powerful DPS who deals massive AoE DMG primarily through her Ultimate. Her kit revolves around building Slashed Dream stacks and applying debuffs to enemies, which fuel her Ultimate and significantly increase its DMG. To maximise her potential, she relies on teammates who can consistently apply debuffs, enabling faster Ultimate use and stronger DMG output.

Acheron's Best Eidolons

When it comes to the best Eidolons to focus on for Acheron, the most important one is her E2. Acheron's E2 lowers her team restriction by reducing the number of Nihility allies needed to trigger her A4 bonus from two to one. This gives her much more flexibility in team building, allowing you to include a different support instead while still maintaining her full DMG potential.
