Supplements are either items that you must have to perform a certain Kung Fu or Chi Kung technique, or items that amplify the effects of a Kung Fu or Chi Kung technique.

For example: Certain charms of Sacred Flower will not activate unless a disciple resides in a "Posessed" State, where it is said that The Mistress of Chaos guides their thoughts and actions. Certain maneuvers of The League cannot be performed unless a disciple is limbered up enough to reside in a "Drunken" State.

To use a supplement, right click on it or put it in your quickslot bar and press the correspoding key.
