Acheron Build 2026: Best Relics, Light Cones & Teams

Acheron Build Overview

Acheron is a 5-star Lightning Nihility DPS who relies on Slashed Dream stacks and Ultimate damage. She ignores Weakness Types and deals massive AoE damage. To get her rolling, you need specific debuffs and fast supports.

Best Light Cones

Choose based on your resources:

• Along the Shore (5-Star): Best in slot. Increases CRIT Rate by 24% and CRIT DMG by 24%. After using Ultimate, CRIT DMG boosts another 24% for 2 turns.
• Cruising in the Stellar Sea (5-Star): Great F2P option from Herta Store. Boosts CRIT Rate by 16%. Against enemies below 50% HP, CRIT Rate increases another 8%.
• Good Night and Sleep Well (4-Star): Top budget pick. Deals 24% increased DMG for every debuff on the target (max 3 stacks).
• Fermata (4-Star): Free option. Increases DMG to Shocked enemies by 20%.

Pro tip: If you lack her signature Light Cone, prioritize CRIT Rate substats to compensate.

Best Relics

Focus on CRIT stats and Speed breakpoints.

Primary Relic Set

• 4-Piece Pioneer Diver of Dead Waters: Increases DMG to enemies with 2+ debuffs by 12%. If you land a CRIT hit, CRIT DMG increases by 4% for 2 stacks. Best for sustained fights.
• 4-Piece Genius of Brilliant Stars: Ignores 10% DEF. If enemy has Quantum Weakness, ignores another 10%. Good for dual-element teams.

Alternative 2-Piece Combos

• 2-Piece Pioneer Diver + 2-Piece Space Sealing Station: 12% ATK and 12% DMG boost.
• 2-Piece Pioneer Diver + 2-Piece Rutilant Arena: 12% DMG and 8% CRIT Rate.

Main Stats & Substats

• Body: CRIT Rate / CRIT DMG
• Feet: Speed (Aim for 120+ SPD)
• Planar Sphere: Lightning DMG
• Link Rope: ATK%
• Substats Priority: CRIT Rate > CRIT DMG > Speed > ATK%

Best Team Compositions

Acheron needs two Nihility teammates to activate her Traces for max damage.

Premium Team

• Acheron (Main DPS)
• Silver Wolf (Debuff / Weakness Implant)
• Kafka (DoT / Debuff Trigger)
• Huohuo (Sustain / Energy Battery)

F2P Friendly Team

• Acheron (Main DPS)
• Pela (DEF Shred / Debuff)
• Guinaifen (Shock / Debuff)
• Lynx (Sustain)

In practice, Silver Wolf is the absolute best partner for Acheron. But Pela works great if you use her Skill frequently.

Skill Leveling Priority

Maximize damage output by leveling in this order:

1. Ultimate (Slashed Dream Cries in Red): Core damage source. Max first.
2. Talent (Slashed Dream): Generates stacks and bonus damage.
3. Skill (Quadrant Ascension): Quick burst damage.
4. Basic Attack: Leave at level 1.

FAQ

1. Does Acheron need 2 Nihility teammates? Yes. Her major Trace requires 2 Nihility allies to activate the 115% DMG boost to her Ultimate.

2. What CRIT Ratio should I aim for? Aim for 1:2 CRIT Rate to CRIT DMG. A good baseline is 70% CRIT Rate and 140% CRIT DMG.

3. Is Acheron F2P friendly? Yes. She works well with 4-star Light Cones and F2P Nihility supports like Pela.

4. How does Acheron generate Slashed Dream stacks? Any ally applying a debuff or using a Skill on an enemy grants 1 stack. At 9 stacks, her Ultimate is unlocked.

5. What Speed should Acheron have? Base Speed is fine, but 120+ SPD allows her to take more actions and generate stacks faster.

6. Can Acheron break Toughness without Lightning Weakness? Yes. Her Ultimate ignores Weakness Types and reduces Toughness regardless of the enemy's actual weakness.
