Genshin Impact 6.7 Meta Guide: Best Older Characters to Rebuild for Stellar-Conduct (Luna VIII Update)

on

⚡ Meta Shift Overview — Why Old Characters Matter Again

Genshin Impact Version 6.7 (Luna VIII) introduces Stellar-Conduct, a Cryo–Electro conversion system built around sustained hit frequency and long-duration reaction uptime, rather than traditional burst damage windows.

Instead of rewarding short damage spikes, the system shifts team value toward consistent elemental application and off-field synergy, allowing older characters with stable uptime kits to regain relevance in endgame compositions.

A key part of this system is the field mechanic known as:

Radiance: Stellar-Conduct

When Sandrone activates her Polestar Field, allied Cryo and Electro abilities begin accumulating Radiance stacks over time. These stacks are then converted into enhanced reaction damage scaling, effectively allowing legacy kits to scale beyond their original multipliers without direct buffs.

This creates a new meta environment where characters are no longer judged purely by burst ceilings—but by how efficiently they can maintain continuous Cryo–Electro pressure inside the field.

🔧 Critical System Rule

❗ Stellar-Conduct is NOT naturally available

To activate Stellar-Conduct:

  • Sandrone (or future enabler units) is REQUIRED

Without her:

  • Cryo + Electro remains standard Superconduct
  • No Radiance scaling occurs
  • No Polestar Field is generated

✔ However:
Once unlocked, F2P-friendly characters become extremely powerful within the system

🌟 Radiance: Stellar-Conduct — Core Engine Explained

Inside the Polestar Field, characters enter:

Radiance: Stellar-Conduct state

This enables:

  • Stored field energy accumulation
  • Periodic pulse release cycles (~fixed interval ICD)
  • Conversion scaling for selected legacy kits
  • Crit-capable system interactions for certain abilities

This is the true reason older characters regain relevance.

📊 Quick Meta Summary (TL;DR)

Character Tier Role in Stellar-Conduct
Yae Miko S+ Direct Radiance scaler (premium off-field DPS)
Fischl S+ Best F2P Electro uptime engine
Beidou S AoE stack amplifier (NOT frequency-based)
Qiqi S Cryo stability + sustain anchor
Diona A+ Shield + Cryo rotation stabilizer
Keqing A Fast Electro applicator
Raiden Shogun A Energy engine / hybrid support
Wriothesley A Sustained Cryo DPS
Cyno B+ High DPS, rotation restrictive
Razor B On-field Electro speed driver
