When you are close to death, your body can convert keif into lifesaving medicine.
Prerequisite(s): Sahir-Afiyun or keif addict.
Benefit(s): If you are brought to 0 or fewer hit points while under the initial effect of keif, you can end the drug’s initial effect as an immediate action. If you do, you gain a number of temporary hit points equal to your Constitution score.
