Brew

You brew a potion with the power of magic. Touch two vials that are in your hands. One is filled with the required ingredients of a common or uncommon potion other than Potion of Giant Strength, however for the liquid to take its effect, it needs to be poured into the other one completely. When you take any amount of liquid from this potion (a sip, a spill or a gulp), the rest of the liquid (if any) disappears.
