Quick answer: White Serpent & Crimson Viper is the reward for defeating Bai Chilian at the Threadbound Great Tree in Crimson Forest. It is a Dual-Wield weapon with 260 Damage and 110 Guard Break.
Where to get White Serpent & Crimson Viper
The weapon drops from Bai Chilian, Lady of the Twin Serpents, a Chapter 1 boss in Crimson Forest. She waits in the blue flower field beyond the Threadbound Great Tree bell. To reach that bell, you first solve the mist portal puzzle in the Mirrorwood Depths. Rest at the bell before you move on.
From the bell, cross the flower field toward the huge twisted tree hung with threads, then walk into the fog ahead to start the fight. Partway through, Bai Chilian enters a second phase as Bai Chilian, the Sacrificial Serpent.
Once the fight and its closing scene end, you wake beside a crane statue in the Village of Lu. The map labels this spot “Place of Awakening”. Three reward cards appear there:
- Story Item: “Broken Illusory Pipa“
- Weapon: “White Serpent & Crimson Viper”
- Accessory: “Resonance Talisman“
The card displays the prompt, “Equip the new weapon now?” Choose from Advanced (T); Confirm (Space); or Back (Esc). The weapon is yours once the card appears.
White Serpent & Crimson Viper stats and moves
| Stat | Value |
|---|---|
| Type | “Dual-Wield” |
| Damage | “260” |
| Guard Break | “110” |
The card describes the pair as “A nimble, graceful short blade paired with a sinuous, powerful long blade. Together, they dance like twin serpents, shifting through endless variations.”
Each blade has its own combo, and each is tied to a different input:
- “Standard Combo” (left click three times): “Perform a series of swift strikes with the Crimson Viper.”
- “Sha-Chi Combo” (F, F): “Perform a series of slashes with the White Serpent long blade.”
The short blade is the Crimson Viper and handles your left-click strikes, while the White Serpent long blade handles the F combo. Its execution is a Ranged Execution, used on a distant enemy that is low on HP.
Twin Serpent Dance
Twin Serpent Dance uses both blades in one combo. To perform it, “Repeatedly alternate” left click and F, or F and left click, “to perform [Twin Serpent Dance], an endlessly looping combo. Damage increases continuously during the combo.”
Either starting input works. Keep switching between the two buttons and the loop carries on, with its damage climbing for as long as the combo continues.

 Serpent Rattle: Red | Crimson Forest |
 Serpent Slough: White | Meigu Lake |
