The super attack potion is a potion used in Stealing Creation. It can be made with Sacred clay at a Creation kiln. Each tier is a different fill level of the potion. Class 1 clay could be made into a one-dose potion, and class 5 clay, a five-dose potion (see table below). After drinking all doses the potion disappears, without leaving a vial of any kind behind.
As with all Stealing Creation potions, you cannot combine their doses.
