You have intertwined your familiarity with keif and magic to unlock strange powers of enchantment and necromancy.
Benefit: You can easily recognize all forms of keif, including tainted or false forms, and gain a +5 competence bonus to Appraise checks made to determine the value of keif or realize that a substance is not the real thing. You gain a +1 bonus on Fortitude saving throws and a +2 bonus on saving throws against poison. This feat counts as the Endurance feat for the purpose of qualifying for the Diehard feat.
Note: “Keif” is a fictional drug much like cannabis.
