Arder mushrooms are an item used during the fight with Duke Sucellus. They are picked from arder mushrooms found at the west side of the asylum, past the extremities.

They are ground into arder powder, which are mixed in the Fermentation Vat alongside musca powder and salax salt to create arder-musca poisons to wake the Duke.

You will get more powder from each mushroom with a higher Herblore level. 2 potions require 3 mushrooms below 80 herblore, and 2 mushrooms at level 80 or higher.
