H1: 黄泉 Build Guide — Best Relics, Light Cones & Teams | GameBeliever

H2: 黄泉 (Acheron) Build Overview

Role: Debuffer / Sub-DPS
Element: Lightning
Path: Nihility
Build Philosophy: Maximizing personal damage through debuff application and high burst window damage.

黄泉 (Acheron) operates at the intersection of debuffer and sub-DPS. Unlike traditional Nihility units who primarily amplify team damage, Acheron leverages debuffs to fuel her own devastating Ultimate. The core of her build revolves around two principles: 1) Applying debuffs consistently to charge her unique Ultimate mechanic, and 2) Maximizing her CRIT DMG to deliver massive, team-wide burst damage when her Ultimate is ready.

This build works because it transforms Acheron from a simple enabler into a primary damage threat. By prioritizing stats like CRIT Rate, CRIT DMG, and Attack Percentage, and equipping relic sets that amplify her damage potential based on debuff presence, she becomes a self-sufficient carry. Her innate synergy with debuff-inflicting Light Cones and teammates creates a powerful feedback loop: she applies debuffs, deals more damage, and helps the team defeat enemies faster. This guide will detail every facet of this high-potential build.

H2: Best Relics for 黄泉 (Acheron)

H3: Best 4pc Set

Set: Pioneer Diver of Dead Waters
Why it’s Best-in-Slot: This set is tailor-made for Acheron’s playstyle. The 2-piece bonus increases CRIT Rate by 4% for each debuff on the target, up to 12%. Given Acheron’s kit and typical team compositions, maintaining 2-3 debuffs on enemies is easily achievable, granting a significant and nearly unconditional CRIT Rate boost. The 4-piece bonus increases CRIT DMG by 12% against debuffed enemies and a further 8% after using her Ultimate. This perfectly aligns with her burst window, making her follow-up attack and Ultimate hit significantly harder. This set directly solves her stat needs while amplifying her core mechanic.

H3: Alternative Sets

2pc + 2pc Combinations:

• Pioneer Diver of Dead Waters (2pc) + Musketeer of Wild Wheat (2pc): A strong early-game or transitional set. The Pioneer 2pc provides the universal CRIT Rate, while Musketeer’s 2pc gives a flat 12% ATK. This is a safe, effective combo if you have exceptional substats on Musketeer pieces but lack a full 4pc Pioneer.
• Pioneer Diver of Dead Waters (2pc) + Firmament Frontline: Glamoth (2pc): Use this if your Acheron is built with enough SPD to activate Glamoth’s 18% DMG bonus (typically needing 135 SPD or 2 turns before enemies). It’s a potent damage-focused combination for faster-paced teams.

When to Use: Use the 4pc Pioneer set as your ultimate goal. The 2pc+2pc combos are excellent for filling gaps while farming or if your substats heavily favor the alternative pieces. Prioritize the 2pc Pioneer bonus regardless.

H3: Best Planar Ornaments

Best-in-Slot: Firmament Frontline: Glamoth
For most teams, reaching the 135 SPD threshold (or leveraging the 2-turn window) is feasible. Glamoth provides a massive, unconditional 18% All-Type DMG bonus, which is a direct multiplier to Acheron’s entire damage kit. It’s universally powerful for a damage-focused build.

Alternative Options:

• Inert Salsotto: A reliable alternative if you struggle to hit the SPD breakpoint for Glamoth. It provides an 8% CRIT Rate and boosts Ultimate and Follow-Up Attack DMG by 15%. This is perfect for Acheron, as a significant portion of her damage comes from her Ultimate. A 5% CRIT Rate body main stat can help reach this set’s requirement.
• Pan-Cosmic Commercial Enterprise: Use this only if you are building Acheron with an Effect Hit Rate rope to guarantee her debuffs land against high-Effect Resistance enemies. It converts 25% of EHR to ATK%, up to 25%. A niche but viable option for specific high-difficulty content.

H3: Recommended Main Stats

• Body: CRIT Rate or CRIT DMG. Choose whichever allows you to reach a 1:2 CRIT Ratio. With the Pioneer 2pc bonus, a CRIT DMG body often becomes optimal.
• Feet: Speed (SPD). Speed is crucial for taking more turns to apply debuffs, charge her Ultimate faster, and potentially activate planar ornament bonuses. ATK% Feet are only considered if you can consistently reach key SPD breakpoints (like 134 or 143) via substats alone.
• Planar Sphere: Lightning DMG Boost. This is the highest damage increase for her, directly scaling all her abilities. ATK% Sphere is a viable filler but inferior.
• Link Rope: Attack Percentage (ATK%). This provides the largest raw damage boost for her personal kit. An Energy Regeneration Rate (ERR) rope can be considered in specific, highly optimized teams to charge her Ultimate faster, but ATK% is the standard recommendation for damage.

H3: Substats Priority

Priority Order: CRIT Rate / CRIT DMG > SPD > Attack % > Effect Hit Rate (EHR)

• CRIT Stats: Aim for a 1:2 ratio of CRIT Rate to CRIT DMG as your primary goal.
• SPD: Secondary but essential. Aim for at least 134 SPD as a baseline to act frequently. Reaching 143 SPD or higher is excellent.
• ATK%: A strong, universally beneficial substat that directly increases all damage.
• Effect Hit Rate (EHR): Only needed to ensure her debuffs (from her skill and potentially Light Cones) land against enemies with high Effect Resistance. For most content, 20-30% EHR from substats is sufficient. Do not sacrifice CRIT or SPD for excessive EHR.

H2: Best Light Cones for 黄泉 (Acheron)

H3: 5★ Light Cones

Signature: Incessant Rain
This is her unequivocal best-in-slot. It provides a massive 24% CRIT DMG increase. More importantly, its secondary effect grants the team 12% All-Type RES PEN after she attacks a debuffed enemy, a rare and powerful multiplier. It also increases DMG to enemies she has debuffed by 12%. This Light Cone perfectly encapsulates her entire playstyle and provides unmatched offensive power.

Other 5★ Options:

• Those Many Days (Kafka’s Signature): A strong alternative. It grants a high ATK% bonus and allows her to apply Shock when using her Ultimate, which synergizes with her Lightning affinity and can help charge her Ultimate faster in certain scenarios.
• Patience Is All You Need (Black Swan’s Signature): Provides ATK% and SPD, but its main mechanic is about applying Arcana stacks, which Acheron does not do. It’s a decent stat stick but highly suboptimal compared to other options.

H3: 4★ Light Cones

Best Choices:

• Resolution Shines As Pearls of Sweat: The premier 4-star option. It has a high base ATK and its effect increases all DMG taken by enemies after the wearer attacks them, which is a universal team damage boost. It’s an excellent support-oriented Light Cone that also benefits Acheron.
• Eyes of the Prey: A budget-friendly option that provides a useful amount of Effect Hit Rate and increases the DoT DMG of enemies afflicted by the wearer. While not perfect, the EHR helps ensure her debuffs land.

Event Light Cones: Check for any limited-time Nihility Light Cones from events (e.g., “Trembling of the Heavens”). These are often powerful 4-star alternatives that are free to Superimpose 5.

H3: F2P Light Cones

Budget Choices:

• Loop: Obtainable from the Herta Store. Provides a straightforward ATK% boost. Its secondary effect to increase DMG to Frozen or Imprisoned enemies is situational but the ATK% is reliable.
• Resolution Shines As Pearls of Sweat (if acquired) remains the best 4-star option even for F2P players.

H3: Light Cone Comparison

Light Cone	Rarity	Key Effect	Why Use It?
Incessant Rain	5★	CRIT DMG & RES PEN	Unmatched personal and team damage boost. Best-in-Slot.
Those Many Days	5★	ATK% & Shock Application	Strong stat stick, good synergy for Ultimate charging.
Resolution Shines	4★	All-Type DMG Taken increase	Excellent team utility and high base ATK. Best 4-star.
Eyes of the Prey	4★	EHR & DoT DMG	Good for ensuring debuffs land, filler option.
Loop	3★	ATK%	Simple, reliable damage boost for absolute budget builds.

H2: Stats Breakpoints & Targets

• CRIT Rate Target: Aim for 80-90% CRIT Rate when considering her Pioneer 2pc bonus. If using a CRIT DMG body, her personal rate from substats + Light Cone should be ~60-70% before combat bonuses.
• CRIT DMG Target: With a CRIT DMG body and her signature Light Cone, aiming for 180-200%+ CRIT DMG is a realistic endgame goal.
• SPD Breakpoints:
  • 134 SPD: The first major breakpoint, allowing her to take two actions in the first cycle of Memory of Chaos.
  • 143 SPD: The next breakpoint for a third action in the second cycle.
  • Always prioritize reaching a functional SPD breakpoint over minor ATK% gains.
• ATK/EHR/ERR Targets: ATK should be as high as possible after meeting CRIT/SPD goals, typically 2400-2800+ at Level 80. EHR can be 20-30% for debuff consistency. ERR is generally not needed on her unless in very specific, hyper-optimized rotational teams.

H2: Best Team Compositions

H3: Premium Team

Members: 黄泉 (Acheron) + Silver Wolf + Pela + Healer (Huohuo or Luocha)
Why it works: This team is built around maximizing Acheron’s personal damage. Silver Wolf and Pela are premier debuffers who shred enemy DEF and RES, applying multiple debuffs that Acheron’s Pioneer set can exploit. Their debuffs also rapidly charge her Ultimate. Huohuo provides cleansing, energy, and an ATK buff, while Luocha offers effortless sustainability. This team creates an overwhelming debuff storm that Acheron capitalizes on.

H3: F2P Team

Members: 黄泉 (Acheron) + Pela + Tingyun + Natasha
How to play: Pela provides essential DEF shred and debuffs. Tingyun amplifies Acheron’s ATK and provides energy to hasten her Ultimate. Natasha keeps the team alive. This team focuses on buffing Acheron directly, as it lacks the second dedicated debuffer of the premium team. Ensure Tingyun’s buff is always on Acheron and use Pela’s Ultimate frequently.

H3: Alternative Teams

• Double Nihility Core: Acheron + Kafka + Black Swan + Healer: A powerful DoT-hybrid team. Kafka detonates Shock, Black Swan applies Arcana, and Acheron contributes her own debuffs and burst. This team spreads damage sources but may slightly lower Acheron’s personal Ultimate damage compared to a single-target focused team.
• Hypercarry with Supports: Acheron + Bronya + Ruan Mei + Healer: Focuses entirely on enabling Acheron. Bronya advances her turns and buffs DMG, Ruan Mei provides universal DMG% and PEN. This is for brute-forcing content where enemy debuff application is limited.

H2: Gameplay Tips & Rotation

• Skill Rotation: Use her Skill to apply debuffs and generate energy. Her Ultimate is her main source of damage, so the core rotation is Skill > Basic Attack > Skill > Ultimate (depending on energy). Prioritize using Skill on enemies without her debuff to apply it.
• Key Combos: Always pair her Ultimate with team DEF/RES shred from allies like Pela or Silver Wolf for maximum impact. Use her Technique before battle to apply a debuff, giving her an immediate Ultimate charge head start.
• Common Mistakes to Avoid:
  • Neglecting SPD: A slow Acheron charges her Ultimate too slowly and contributes less over time.
  • Ignoring CRIT Ratio: Building high CRIT DMG with low CRIT Rate results in inconsistent, disappointing damage.
  • Overcapping EHR: Don’t sacrifice damage stats for unnecessary Effect Hit Rate. Test her debuff landing rate in relevant content.

H2: Investment Priority

• E0 Viable? Absolutely. Acheron is fully functional and powerful at E0. Her Eidolons are powerful upgrades but not required for her to excel as a sub-DPS/debuffer.
• Key Eidolons:
  • E1: A significant damage boost that increases her Ultimate’s DMG multiplier. Her most impactful early Eidolon.
  • E2: Provides additional Ultimate energy, allowing her to use it much more frequently. A major quality-of-life and DPS increase.
  • E6: Makes her a true hypercarry, granting her a follow-up attack after allies apply debuffs. This fundamentally changes and amplifies her playstyle.
• Light Cone Priority: Her signature Light Cone, Incessant Rain, is a higher priority than her Eidolons for maximizing her damage. It provides a more substantial and immediate power spike than E1. Secure the Light Cone first, then consider Eidolons.
