Acheron Stats

Is Acheron Worth Pulling?

Acheron is a remarkably powerful DPS that can annihilate enemies with her powerful Ultimate that can ignore weakness type and does not have an energy cost.

If you are looking for a very strong Hypercarry that can also perform well against enemies not weak to Lightning, then Acheron is a must-pull!

Acheron's Best Builds

Nihility DPS Build

Despite being a Nihility unit, Acheron works as your typical DPS who takes advantage of CRIT Rate and CRIT DMG stats.

Speed boots are great for Acheron since they increase her action count, which helps to increase Slashed Dream stacks. It's also good if you're trying to hit speed breakpoints for Ornaments that require it. However, you can also use ATK% boots for Acheron if she's paired with Sparkle or Bronya.

As for her Sphere, you can choose between Lightning DMG and ATK%, depending on which has better sub-stats. ATK% is slightly better since Acheron already has a ton of DMG buffs from her Traces and Signature Light Cone.

Recommended Stat Values

Stat	Recommended Value
CRIT Rate	70% or above
CRIT DMG	160% or above
ATK	3000 - 3500
SPD	101 or 135+

Acheron's Best Teams

Acheron F2P Team (Free to Play)

DPS	Support	Support	Healer
Acheron	Asta	Trailblazer (Fire)	Lynx

In this free-to-play team, Asta and the Fire Trailblazer can debuff the enemy through Burn and Taunt respectively. The Fire Trailblazer can equip the Trend of the Universal Market to apply Burn on enemies.

Since Acheron's kit becomes stronger when Nihility units are in the party, we recommend replacing your Supports as soon as you get debuffers.

Acheron Hypercarry Team

DPS	Support	Support	Sustain
Acheron	Jiaoqiu	Pela	Aventurine

Acheron's best team at Eidolon 0 and 1 consists of two other Nihility units to max out the DMG buff from her Bonus Ability.

Jiaoqiu and Pela can debuff the enemies on their turn to add stacks for Acheron's Slashed Dream. Pela can equip the Resolution Shines As Pearls of Sweat to have more chances of applying debuffs on an enemy.

Aventurine can provide shields to the party and implant a debuff on the enemy with his Ultimate. Unless Jiaoqiu is in the team, Preservation units paired with Acheron should ideally equip Trend of the Universal Market to apply a fire DoT on enemies when attacked.

Acheron E2 Team

DPS	Nihility	Harmony	Sustain
Acheron	Jiaoqiu	Sunday	Aventurine

If you unlocked Acheron's 2nd Eidolon, you can replace your second Nihility unit with a Harmony unit and still activate the full DMG buff from Acheron's Bonus Ability.

Acheron's Best Relics and Ornaments

All Recommended Relics and Ornaments

Relics	Rating & Merits
Pioneer Diver of Dead Waters x4	★★★★★ - Best Pioneer Diver of Dead Waters is Acheron's best Relic set as it provides her CRIT Rate and increased CRIT DMG against debuffed enemies.
Scholar Lost in Erudition x4	★★★★☆ - 2nd Best Scholar Lost in Erudition is also great for Acheron since it gives her CRIT Rate and increases the damage of her Skill and Ultimate.
Pioneer Diver of Dead Waters x2 Band of Sizzling Thunder x2	★★★☆☆ - 3rd Best A mix of Pioneer Diver of Dead Waters and Band of Sizzling Thunder is also good since it increases Acheron's Lightning DMG and DMG dealt against debuffed enemies.
Ornaments	Merits
Izumo Gensei and Takama Divine Realm	★★★★★ - Best Izumo Gensei can increase Acheron's CRIT Rate if there's at least one Nihility unit in the party. This works extremely well for Acheron as her best teams consist of other Nihility units.
Firmament Frontline Glamoth	★★★★☆ - 2nd Best Firmament Frontline Glamoth's DMG buff can work well with Acheron as long as she has at least 135 SPD.
Inert Salsotto	★★★☆☆ - 3rd Best Inert Salsotto can provide a small CRIT Rate buff and increase Acheron's Ultimate DMG.

Relic List & Guide

Acheron's Best Light Cones

All Recommended Light Cones

Light Cone	Why We Recommend It
Along the Passing Shore	★★★★★ - Best Along the Passing Shore is Acheron's best Light Cone by a long shot. This increases Acheron's DMG and provides an extra Slashed Dream stack when she uses her Skill.
Boundless Choreo	★★★★☆ - Great Boundless Choreo is Acheron's best 4-star Light Cone since it provides a permanent CRIT Rate boost and can deal increased CRIT DMG on slowed and DEF-reduced enemies.
Good Night and Sleep Well	★★★★☆ - Great Good Night and Sleep Well is another great 4-star Light Cone that increases Acheron's DMG to an enemy affected with a lot of debuffs.
Incessant Rain	★★★★☆ - Great While the Effect Hit Rate buff is negligible, Incessant Rain is still a great Light Cone for Acheron since it provides CRIT Rate if the target has three or more debuffs. Incessant Rain also has a chance to implant an Aether Code debuff on an enemy, which Acheron can use to get more Slashed Dream stacks.
In the Name of the World	★★★☆☆ - Good In the Name of the World can increase Acheron's DMG to debuffed enemies. The ATK and Effect Hit Rate buff is only an okay buff since it only affects Acheron's Skill.
Patience Is All You Need	★★★☆☆ - Good Patience Is All You Need increases the damage dealt by Acheron and provides a stackable SPD buff.

Light Cone List & Guide

Should I Get Acheron's Light Cone?

Acheron's Along the Passing Shore Light Cone is significantly stronger compared to the other Nihility Light Cones. This allows Acheron to deal a lot of DMG and increase her Slashed Dream count by two when she uses her Skill.

While getting Acheron's Light Cone is ideal, there are other viable options such as Good Night and Sleep Well or any Light Cone that provides a DMG buff.

Acheron's Gameplay Guide

Skill Gains Slashed Dream and Deals AoE DMG

When Acheron uses her Skill on an enemy, she will gain a stack of Slashed Dream and apply a Crimson Knot stack on the main target.

Acheron will also deal Lightning DMG to enemies adjacent to the enemy target.

Talent Lets Acheron Unleash Her Ultimate Faster

Aside from using her Skill, Acheron can also gain Slashed Dream stacks by having other allies inflict debuffs on an enemy. Enemies that apply debuffs on themselves or other enemies can also increase the Slashed Dream count.

When Acheron gains 9 Slashed Dream stacks, she can unleash her Ultimate.

Crimson Knot Application

Enemies will also receive a Crimson Knot stack when they receive a debuff. If multiple enemies are inflicted with a debuff at the same time, Crimson Knot will only be inflicted on the enemy with the most Crimson Knot stacks.

If an enemy leaves the battle or is taken out, their Crimson Knot stacks will be transferred to the enemy with the most Crimson Knot stacks.

Acheron's Ultimate Ignores Enemy Weaknesses

Acheron's Ultimate can reduce an enemy's Toughness regardless of their Weakness Type and reduce their All-Type RES.

Once Acheron's Ultimate is unleashed, you can manually select the target for the first three attacks. On the fourth attack, Acheron will deal DMG to all enemies.

Enemies with Crimson Knot Take Increased DMG

Enemies with Crimson Knot stacks will receive more DMG from Acheron's Ultimate. Every time Acheron hits an enemy with her Ultimate, three Crimson Knot stacks will be removed.

Instant Kill Enemies with Technique

Acheron's Technique can instantly kill an enemy in the overworld. A Technique point will not be consumed if Acheron's Technique does not hit the enemy.

Enemies such as Trotters, Elite enemies, or Bosses cannot be instantly killed and will instead receive Lightning DMG after entering combat. Acheron will also gain a Slashed Dream stack and apply Crimson Knot to a random enemy.

Acheron's Eidolons

Recommended Eidolons

	Why We Recommend It
E1	★★★★★ - Amazing Acheron gets a huge CRIT Rate boost when attacking debuffed enemies. This will let you prioritize more CRIT DMG stats on Acheron's relics.
E2	★★★★★ - Amazing Best stopping-point for spenders. Acheron only needs one other Nihility unit to access the full DMG Boost from her Bonus Ability. Acheron can also gain a Slashed Dream stack at the start of her turn, which lets her access her Ultimate a lot sooner.
E4	★★★★☆ - Great Enemies will take more Ultimate DMG after entering combat. This makes Acheron a pseudo-support unit.
E6	★★★★★ - Amazing Acheron's Basic ATK and Skill can now be considered Ultimate DMG and can reduce enemy toughness regardless of the enemy's Weaknesses.

E2 is a Huge Upgrade to Acheron's Kit

Acheron's 2nd Eidolon provides a huge boost to her kit. Her needing one less Nihility unit in the party can open up team comps that feature Harmony units.

If you want to invest in Acheron and have a ton of Stellar Jades to spare, getting Acheron's E2 will be worth the pulls!
