Honkai Star Rail Acheron kit
Acheron is a 5-Star Lightning character of The Nihility path who deals damage by building and getting rid of stacks to unleash her Ultimate. Acheron also works very well with Nihility debuffers, as her personal damage increases when enemies have multiple debuffs applied.
All of the percentages mentioned below are based on Level 1 Traces.
Here's a summary of Acheron's kit in Honkai Star Rail:
- Element: Lightning.
- Path: The Nihility.
- Rarity: 5-Star.
- Basic Attack: Trilateral Wiltcross - Deals Lightning damage equal to 50% of Acheron's attack to a single enemy.
- Skill: Octobolt Flash - Acheron gains one point of Slashed Dream, inflicts one stack of Crimson Knot on a single target enemy, and deals Lightning damage equal to 80% of her attack to that enemy, as well all Lightning damage equal to 30% of her attack to adjacent enemies.
- Ultimate: Slashed Dream Cries in Red - Acheron Sequentially unleashes Rainblade three times and Stygian Resurge one time, dealing Lightning damage up to 223% of Acheron's attack to a single target enemy, as well as Lightning damage up to 180% of Acheron's attack to other targets.
- Rainblade - Deals Lightning damage equal to 14.4% of Acheron's attack to a single target enemy and removes up to three stacks of Crimson Knot from the target. When Crimson Knot is removed, Acheron immediately deals Lightning damage equal to 9% of her attack to all enemies. For every stack of Crimson Knot removed, this damage multiplier is additionally increased, up to a maximum of 36%.
- Stygian Resurge - Deals Lightning damage equal to 72% of Acheron's attack to all enemies and removes all Crimson Knots, but Crimson Knot can't be applied to enemies during the Ultimate.
- Talent (passive ability): Atop Rainleaf Hangs Oneness - When Slashed Dream reaches nine stacks, Acheron's Ultimate can be unleashed, which lowers enemies' Toughness regardless of their Weakness Types and also lowers their All-Type Resistance by 10% until the end of Acheron's Ultimate. When any unit inflicts debuffs on an enemy while using their ability, Acheron gains one stack of Slashed Dream and inflicts Crimson Knot on that enemy target. If the ability used inflicts a debuff on multiple enemies, one stack of Crimson Knot is inflicted on the enemy with the most Crimson Knot stacks. This effect can only trigger once per every ability usage. When Acheron is on the field and an enemy leaves the field or is defeated, their Crimson Knot stacks will be transferred to the enemy target with the most Crimson Knot stacks.
- Technique (overworld ability): Quadrivalent Ascendance - Acheron immediately attacks the enemy. At the start of each wave, she gains Quadrivalent Ascendance, dealing Lightning damage equal to 200% of Acheron's attack to all enemies and reducing Toughness of all enemies irrespective of Weakness Types. When weakness is broken, triggers the Lightning Weakness Break effect.
- Quadrivalent Ascendance - After using her Ultimate, Acheron gains one point of Slashed Dream and inflicts one stack of Crimson Knot on a single random enemy. If attacking a normal enemy, Acheron immediately defeats them without entering combat. If an enemy isn't hit while using Acheron's Technique, no Technique Points are consumed.
- Bonus Trace 1: Red Oni - At the start of battle, Acheron immediately gains five stacks of Slashed Dream and applies five stacks of Crimson Knot to a random enemy. When Slashed Dream reaches its upper limit, for every point of Slashed Dream that exceeds the limit, Acheron gains one stack of Quadrivalent Ascendance. Also increases the maximum stackable count for Quadrivalent Ascendance to three.
- Bonus Trace 2: The Abyss - When there are one or two other characters following the Path of Nihility in the team, the damage of Acheron's basic attack, Skill, and Ultimate increases to 115% or 160% of its original damage, respectively.
- Bonus Trace 3: Thunder Core - When the Rainblade from Acheron's Ultimate hits enemies with Crimson Knot, her damage increases by 30%, stacking up to a maximum of three times and lasting for three turns. Additionally, Acheron deals six hits of damage when Stygian Resurge is triggered, with every hit dealing Lightning damage equal to 25% of Acheron's attack to a single enemy. This is considered Ultimate damage.
