Items/Compounds

Compounds are items that are typically created through a skill called "Compounding" and can be created manually or through the use of a Legendary Weapon. Although many compounds can be made through the use of a Legendary Weapon, all products of the Legendary Weapon will be normal quality despite the input ingredients. (Using any low, mid, or high quality ingredient will result in normal quality products). Some naturally occurring plants share the same use or effect as certain compounds so they can sometimes be used as a substitute and are therefore included here as well.
