Wicked Gnarly Potion
From MHWiki
Wicked Gnarly Cheese Curd Potions are dropped by Curious Chemist mice in the Great Gnarled Tree. Using a Wicked Gnarly Cheese Curd Potion converts either Brie or SUPER|brie+ cheese into Wicked Gnarly cheese.
The type of cheese used in the conversion determines the amount of Wicked Gnarly cheese generated and the gold required per piece. Hunters can convert six SUPER|brie+ cheese into six Wicked Gnarly cheese at 200 gold per piece for a total cost of 1,200 gold. Alternatively, they can convert three Brie cheese at 800 gold per piece into three Wicked Gnarly cheese for a total cost of 2,400 gold.
