{{sidebar|Demonic Essences and Availability|It should go without saying, but creation of demonic essences is approved of by very few civilized societies, for a very large number of reasons. While the price given here is one that can be considered 'average' insofar as such a thing is possible, your GM is under no obligation to make such things available, or if they choose to do so, available at this price. You have been warned.}}
To make a lesser demonic essence, a demon of at least CR 7 is needed, along with an alchemy lab (either portable or fixed-location). The demon must be held immobile, unconscious or something else that prevents it from escaping or interfering with the process. The would-be alchemist must also make a DC 22 Knowledge (the planes) or Craft (alchemy) check, and spend an hour of time. If the check is successful and the demon doesn't escape or interfere, it is completely destroyed, and it becomes a least lesser demonic essence. This action can be done only on the demon's home plane.
