Boletus is an ingredient in Divinity: Original Sin 2
"Often chewed by archers before battle to still their shaking hands, this mushroom is colloquially known as 'Hunter's Breakfast'."
Boletus is used to create potions which boost finesse. You can eat it to gain one finesse for two turns. You can also use a poison source on Boletus to add 9 poison damage to it. Due to its rarity, you'll need to purchase it from merchants throughout the game if you want to stockpile large quantities of finesse potions.
Where to find:
- Sold by Merchants
- Found rarely around the game world.
- Can be retrieved by Han
- One can be found near the two cows if you are doing the Treated Like Cattle quest (due south of the witch's house)
