Where can I find Salum Bomb Saltpeter? (The Witcher 3: Wild Hunt)

Cornell Haynes
Samum

saltpeter is lying around in almost every chest ... well, it’s also sold by artisans, I wouldn’t call the current itself useful ..
it’s easier to shave off and toucan with a crossbow in the approach of flying ones while acclimatizing

According to the plot, when you are preparing to kill a griffin, you meet an herbalist. She has it for sale.

sold by all herbalists.
