Acheron

Acheron is one of Honkai: Star Rail's defining hypercarries. Her damage comes from stacking Slashed Dream debuffs on enemies and then unleashing a devastating Ultimate, so she pairs best with Nihility teammates who apply debuffs rapidly.

How to Play

Run Acheron with debuff-heavy supports and a Harmony amplifier. Her ceiling keeps her at the top of the HSR tier list.

Best Build

Light Cones: Along the Passing Shore (signature), Good Night and Sleep Well, or Cruising in the Stellar Sea. Relic Set: Pioneer Diver of Dead Waters (4-piece). Planar Ornament: Izumo Gensei and Takama Divine Realm (2-piece). Main Stats: Body: CRIT Rate / CRIT DMG. Feet: SPD. Planar Sphere: Lightning DMG. Link Rope: ATK%. Substats: CRIT Rate, CRIT DMG, ATK%, SPD.

Best Teams

1. Double Nihility: Pela, Black Swan, Fu Xuan.
2. Debuff Stack: Pela, Silver Wolf, Aventurine.

Kit Overview

• Skill: Deals Lightning DMG to one enemy and adjacent targets, building Slashed Dream stacks.
• Ultimate: Rainblade and Crimson Knot hits that scale off debuffs on enemies, unleashing massive AoE damage.
• Talent/Role: Nihility nuker who counts debuffs across the field to power her Ultimate; thrives in debuff-heavy teams.

Pros and Cons

Pros: Top-tier AoE and single-target burst, can work at low investment, Ultimate ignores some defensive mechanics. Cons: Needs at least 3 debuffs on enemies to maximize, very team-dependent on Nihility supports.
