The addition of Penacony in the Honkai: Star Rail 2.0 update also introduced us to new characters such as Aventurine and Acheron, both of whom will be available in version 2.1, which will be released on March 27, 2024.

Here are the details about Acheron’s traces, leveling materials, and more, as well as for her signature Light Cone, “Into the Yawning Chasm.”


Acheron-Honkai: Star Rail
  • Path: Nihility
  • Type: Lightning

Character Overview

Acheron is a DPS character who accumulates charges by inflicting debuffs on enemies to unleash her Ultimate. With her Ultimate, Acheron ignores enemy Weakness Types, drains all enemies’ Toughness, and reduces their Type RES.

Acheron’s Technique can also instantly eliminate some enemy targets during exploration.

Character Preview


A drifter claiming to be a Galaxy Ranger, her true name is unknown. She walks the cosmos alone, carrying a long sword. Though aloof and taciturn, her blade flicks out like lashing lightning. Yet, she always strikes with her scabbard, never drawing the sword free.

Personal Matters

About Self: Habits

In the hazy memories of my distant hometown, there were often heavy thunderstorms. Fearing their makeup would be ruined by the rain, girls carried makeup with them wherever they went. I have no reason to do so anymore, but the habit still remains.

Chat: Weapon

If one carries a blade, it’s bound to be used to cut something down. My reason for drawing my sword – past, present, or future- remains singular.

Hobbies: Peaches

They embody life’s delights and pleasures, but are equally fragile and short-lived… Such regret is inevitable, so let it be.

When any unit inflicts debuffs on an enemy target while using their ability, Acheron gains 1 point of Slashed Dream and inflicts 1 stack of Crimson Knot. If debuffs are inflicted on multiple targets, then the 1 stack of Crimson Knot will be inflicted on the enemy target with the most Crimson Knot stacks. This effect can only trigger once every ability usage.

When Acheron is on the battlefield, when an enemy target leaves or any unit is defeated, their Crimson Knot stacks will be transferred to the enemy target with the most Crimson Knots left on the battlefield.

Acheron Drip Marketing

Acheron was first revealed as a Lightning Nihility 5-Star character on January 23, 2024, through the official Honkai: Star Rail X account. She would be voiced by Allegra Clark, who is notable for her voice acting for characters such as Beidou from Genshin Impact.

Acheron character model leak

Her character model was leaked last month, which garnered considerable attention from the Honkai: Star Rail players. This is the transformation of Acheron whenever she uses her Technique in the overworld as well as her ultimate.

Acheron’s kit and skills

Acheron’s Preliminary Kit was leaked through HomDGCat. It listed her skills, Traits, and Eidolons. These are all subject to change, as there is still incomplete data, especially regarding the Traits and Eidolons. Nonetheless, her Technique caught the players’ attention, and they initially thought it was absurd.


  • Basic ATK: Deals Lightning DMG based on ATK, and gains 1 Energy Point.
  • Skill: Deals Lightning DMG to a single target and adjacent targets based on ATK and gains 2 Energy Points.
  • Ultimate: Consumes all Energy Points and enters the Ultra Pose, performing the following actions within 1 turn. During Ultra Pose, all enemies’ All-Type RES is decreased. This is the three-part ultimate which deals Lightning DMG to the enemies.
  • Talent: Energy Point – Acheron initially has 0 Energy Points. When she has enough Energy Points, her ult will be available. She would apply 1 Lotus to a target or automatically select the one with the most Lotus, which prioritizes Elite enemies.
    Lotus Bloom – Consumes Lotus held by a single target, with an upper limit of 3 per target. This deals Lightning DMG to all targets and counts as Ultimate DMG. This DMG is increased by 100% for every Lotus consumed, independent from other buffs.
  • Technique: Immediately kills an enemy target. If unsuccessful, it deals Lightning DMG to all targets after entering battle and gains some Energy Points.

In another leak of Acheron’s Kit through Dimbreath, they detailed the materials needed for her, which are: Shape Shifter’s Lightning Staff, Past Evils of the Borehole Planet Disaster, Heaven Incinerator, Starfire Essence, Fiery Spirit, Dream Making Engine, Dream Flow Valve, and Dream Collection Component.

This also included many changes to the description of Acheron’s Skills, from her Basic ATK to her Technique, which now states “Immediately attacks the enemy” instead of “Immediately kills the enemy.”

Changes occurred during the Honkai: Star Rail 2.1 Beta, which included many of her Eidolons (1, 4, and 6), Talent (Red Oni), and her Technique. This may be getting closer to what players will actually get when she is released for 2.1.

Acheron’s Skill, Ultimate, and Technique Animation

Many users previously leaked the full videos of Acheron’s Skill and Ultimate on X but have since been removed. Many fans became more excited as they viewed them as it was incredibly smooth. Here are a few clips remaining which showcases Acheron’s animations in-game:

Honkai: Star Rail will host the version 2.1 live stream on March 16, 2024, at 7:30 pm (UTC+8). You can watch the live stream on their official YouTube channel or through Twitch. This page will be updated once her official kit is released. Do let us know your thoughts on Acheron in the comment section!
