March 29, 2024: We have updated the information based on the Honkai Star Rail 2.1 version release.

Who is Acheron in Honkai Star Rail?

Acheron is a 5-star DPS Nihility character with the Lightning damage type. She is an Emanator of Nihility, claiming to be a Galaxy Ranger. She walks the cosmos alone, only accompanied by her long sword, which she flicks out like a lashing lightning. Described as aloof and taciturn, she mainly strikes with her scabbard, never drawing her Sword free.

Acheron is a very mysterious character and we barely know anything about her even though she has featured a lot in the Honkai Star Rail 2.0 and 2.1 trailblazing missions. We only know that she is after the Watchmakers Legacy,like every other party in Penacony, but what drives her is still unknown.

Acheron Kit and Best Cycle Rotation (At Max Level)

Acheron’s kit may look very complicated,but it is quite simple and extremely overpowered. Her kit allows her to reduce enemy defenses, break toughness irrespective of the weakness type, and deal massive AoE and Single-target damage, all in the same turn. Let’s look closer at her kit to know how to play Acheron’s best build correctly.

Acheron’s kit has two main parts, Crimson Knots and Slashed Dream. As Acheron doesn’t have energy,she uses her Ultimate when the Slashed Dream count reaches 9.Crimson Knots are inflicted on enemies andenemies with Crimson Knots take increased Ultimate damage from her. Acheron can gain Slashed Dream and inflict Crimson Knot stacks by using her Skill, or when any ally debuffs an enemy. Her Ascension abilities also allow her to gain some at the start of the battle.

Now, her Ultimate deals Single-target lightning damage on an enemy. If that enemy is marked with Crimson Knot, Acheron does an AoE lightning attack.This continues 3 times and then all the Crimson Knots are consumedand Acheron unleashes a much stronger AoE lightning attack. Players can choose the main target during her Ultimate for all three consecutive attacks.In-game Screenshot Captured by: Sanmay Chakrabarti

Her Talent is extremely broken, as it reduces All Type Resistance of enemies by 25% when Acheron uses her Ultimate, while also allowing her todeal Toughness damage irrespective of the enemy weakness type(similar to Xueyi). The ideal way to play Acheron is to constantly use her Skill to inflict Crimson Knot and gain Slashed Dream while dealing good damage, and then use her Ultimate when it is unlocked.

Also,her Technique can instantly kill enemieswithout entering combat. This ability also works in the Simulated Universe, only elite enemies, bosses, or trotters are safe from the insta-kill mechanic. Other than that, the technique can be used multiple times to install kill a normal group of enemies, outside combat.

Acheron’s kit is extremely broken, and it gets more overpowered with the correct Relics, Planar Ornaments, and stats. Here are the best Relics, Planar Ornaments, and Stats for the best Acheron build.

Best Relics for Acheron in HSR

The 4-piece Pioneer Diver of Dead Watersis the best relic set for Acheron as it significantly increases her damage to debuffed enemies. Other than that, the 4-piece Band of Sizzling Thunder is also a good pick as it increases Lightning damage and the damage of her Skill attacks.

The 4-piece Genius of Brilliant Stars is among the best relic sets for any DPS as the Defense ignores the percentage of the 4-piece is extremely useful. This set is particularly good for Swarm Disaster.

Best Planar Ornaments for Acheron in HSR

The2-piece Izumo Gensei and Takama Divine Realmis perfect for Acheron, as it increases the wearer’s Crit Rate by 12% when at least one other ally follows the same path. Acheron already needs other Nihility characters in the team, so this planar ornament is perfect for her.

Rutilant Arena is the best alternative Planar Ornament setfor Acheron. It increases her Crit Rate by 8% and Skill Damage by 20%. The 2-piece Inert Salsotto is another good choice for Acheron, increasing her Crit Rate and Ultimate Damage.

Main and Sub Stats for Acheron

When it comes to the main and sub-stats for Acheron, simply focus onstacking as much Crit Rate, Crit Damage, and Attack % as possible.Try to hit a ratio of 70% Crit Rate and 170% Crit Damage with the stats. Other than that, use a Speed Boost tohit the Speed breakpoints, as the more turns Acheron has, the quicker her Ultimate recharges.

Best Light Cones for Acheron Build in HSR

Acheron’s best Light Cone is Along the Passing Shore, which is her signature Light Cone. Other than that,Good Night and Sleep Well is the best 4-star Light Cone for Acheron, as it increases her damage based on the debuff inflicted on the enemies. We Will Meet Again is one of the new Forgotten Hall Light Cones and it is a good F2P option at superimposition 5.

HSR Acheron Eidolons

Acheron’s Eidolons are extremely brokenand make her kit even more overpowered. Her E1 gives her a straight 18% Crit Rate increase when dealing damage to debuffed enemies. Acheron’s E2 reduces the Nihility character requirement for her trace and allows her to gain 1 stack of Slashed Dream and inflict Crimson Knot at the beginning of her turn.Her E4 makes enemies vulnerable to Ultimate damagewhile her E6 increases her Crit Damage and Ultimate Damage by 60% whilemaking her Skill and Basic Attack damage be considered as Ultimate Damage.

Overall, an E6 Acheron is going to be the most broken DPS in Honkai Star Rail, and no other DPS units,likely even Jingliu, may get close to her. However, her kit is broken by itself and doesn’t need any investment in her Eidolons.

Expected Acheron Traces and Ascension Abilities in HSR

Ascension Abilities:

Stat Boosts:

When it comes to Acheron’s ascension abilities,her A2, A4, and A6 are must-haves. Her A2 gives her additional stacks of Slashed Dream and inflicts Crimson Knot on enemies, allowing her to use the Ultimate from the get-go. The A4 ability increases her Basic Attack, Skill, and Ultimate Damage to 160% of the original damagewhen your team has two other Nihility characters. Acheron’s A6 ability makes enemies inflicted with Crimson Knot take increased damage.

Best Team Comps for Acheron in Honkai Star Rail

Acheron’s best teams will feature at least one other Nihility character, to best utilize her A4 ability. Her best team will be alongside Black Swan, Sampo, and Fu Xuan. She is not a DoT character, however, she banks a lot on debuffs and DoTs are debuffs.

So,Black Swanis one of the best Nihility DPS partners for Acheronas she can constantly apply debuffs, while also dealing insane DoT damage. Sampo works extremely well with Black Swan, especially if you have his Eidolons, and Fu Xuan is a solid Sustain for any team.

Other than that, you can also usePela, Bronya,Guinaifen,Ruan Mei, or Silver Wolfnext to Acheron.Tingyuncan also work with Acheron, but the energy recharge of Tingyun’s Ultimate will be wasted on Acheron.

Should You Pull for Acheron in Honkai Star Rail?

Yes, if you have Stellar Jades,make sure to do all you can to pull for Acheronas she is going to be one of the best,if not the best, DPS characters in the game. She can do massive single target, AoE, and Blast damage while breaking Toughness irrespective of the enemy weakness type, and her Technique can insta-kill enemies without entering combat. Acheron is one hundred percent a must-pull. Share your thoughts on Acheron in the comment section and tell us if you are going to pull her or not.
