Picking up a lead flask of liquid, you slosh it gently to hear that it is full. As you turn it over in your hands, you notice that the cork is sealed with a thick layer of wax into which magical symbols have been traced. The elven woman takes the flask from your hands and gently sets it down on a nearby shelf. "Last thing we want is for this to accidentally crack," she says with a wry smile. "Let me explain . . "

Originally created by a merchant mage who spent most of his time hauling wares from point A to point B, the potion of packing was used for just that: packing. When released from it's container, it spews forth a thick, white froth which coats objects and quickly hardens into a stiff yet friable material. (We know it today as styrofoam.) At it's most mundane, it is used to coat fragile objects and prevent breakage during travel. However, it can be used as a defense/offensive weapon. Should you decide to aim it at, oh, say, a person, then they are encased in this material and unable to move once it hardens. Of course, they can break out of it with some work, if it is not too thick. The main problem is if the mouth and nose are covered, the victim can easily suffocate.

One flask generally holds 4 doses of potion. One dose can cover an area of 3 square feet - an entire flask would cover 12 square feet. Imagine opening a flask in a small room. You could easily trap everyone inside and they would suffocate quickly since they would be embedded in a solid block. Should a person merely be coated with a layer of the stuff, it's not difficult to remove.
