Overview
Razor's burst summons the Lightning Wolf, converting attacks to Electro and increasing attack speed. His skill deals Electro damage and generates particles. Physical build with Pale Flame and Superconduct (Cryo + Electro) is his highest damage setup for late game.
How to Play
Apply Cryo with Kaeya/Diona, then burst and stay on-field attacking. Superconduct reduces enemy Physical RES, Razor's normal attacks deal Physical damage even during burst. Use skill for particles between burst windows. Razor wants extended on-field time.
Optimal Rotation
Kaeya Burst, Diona Skill/Burst, Razor Skill, Razor Burst, Razor NA combo until burst ends, Kaeya Skill for particles, repeat. Apply Superconduct every rotation for Physical RES shred.
F2P Options
Prototype Archaic or Serpent Spine work well. Kaeya and Diona are free/banner 4★ supports. Pale Flame is farmable. Razor falls off in late-game meta but comfortably clears overworld and early Abyss with Superconduct.
Common Mistakes
Running pure Electro without Superconduct, Physical RES shred adds more damage. Not pairing with a Cryo battery, Razor is energy-hungry. Building Electro DMG goblet on Physical build. Using Razor in late-game reaction teams, modern DPS outscale him.
