The summoning 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 1-dose potion, and class 5 clay, a 5-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, players cannot combine their doses.
