Razor
Who is Razor?
Razor is a 4★ Physical/Electro Claymore on-field DPS from Mondstadt who excels as a Normal Attack Main DPS in Physical or Aggravate builds. His Elemental Burst (Lightning Fang) summons his wolf companion Lupical to grant an ATK SPD bonus and Electro infusion, boosting his sustained on-field damage. He is a straightforward early-to-mid-game carry who is competitive even in mid-game with Aggravate and double Electro support. Source: https://keqingmains.com/q/razor-quickguide/
Kit Summary
Tap for Electro damage and an Electro Sigil (up to 3 Sigils grant Energy on Hold); Hold drains all Sigils for a powerful Electro sweep and Energy restoration.
Summons Lupical — grants Electro infusion on Normal Attacks, ATK SPD bonus, and Electro RES shred on active character. Cannot simultaneously hold another Elemental Burst while active.
His primary DPS source — all builds revolve around maximizing Normal Attack output.

F2P Verdict
Fully viable with Prototype Archaic (craftable) as the weapon and 4pc Pale Flame (Physical) or 4pc Thundering Fury (Aggravate). Always pair with a second Electro unit (ideally Fischl) to lower his ER requirement to ~100–130% and boost off-field Electro damage. Level to 90 in Aggravate for transformative reaction scaling. C4 (+15% DEF Shred on Tap Skill with 100% uptime) is his best constellation. Source: https://keqingmains.com/q/razor-quickguide/
