Honkai Star Rail Acheron Guide: Team Composition
This team maximizes Honkai Star Rail Acheron’s E0 potential using powerful Nihility synergy. Silver Wolf implants Lightning Weakness, Pela reduces DEF, and Gallagher boosts Break DMG and heals, enabling Honkai Star Rail Acheron to rapidly build Crimson Knots for devastating ultimates.
Acheron E0 Best Team
Acheron
Honkai Star Rail Acheron is a Lightning Nihility character who excels at DoT-based AoE damage. Even at E0, she dominates with her Crimson Knot and Slashed Dream mechanic. She shines when supported by allies who debuff enemies or help her gain stacks fast.
Silver Wolf
Silver Wolf is one of Honkai Star Rail Acheron’s best supports. She can implant the Lightning Weakness onto enemies, ensuring Acheron’s DMG is maximized. Her DEF shred, debuffs, and Quantum typing also help in sustaining Nihility resonance effects like increased Break or DoT.
Pela
Pela provides consistent DEF reduction to all enemies, synergizing well with Honkai Star Rail Acheron’s AoE skills. Her Skill and Ultimate strip buffs and reduce enemy resistance, helping Acheron ramp up damage more efficiently, especially in longer or tougher fights.
Gallagher
Gallagher is a top-tier support with healing and Break DMG boost. His Technique inflicts the “Besotted” state, increasing Break DMG taken. This works perfectly with Honkai Star Rail Acheron, whose kit heavily benefits from Break-style synergy and utility support.
