You have intertwined your familiarity with keif and magic to unlock strange powers of enchantment and necromancy.

Prerequisites: Able to cast 2nd-level spells, keif user, and Spell Focus (enchantment) or Spell Focus (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.
