Devil Preparation (3.5e Feat)
From D&D Wiki
Devil Preparation [General]
By learning dark culinary techniques, you have learned to consume the flesh of devils, demons, and other infernals, absorbing their taint and some of their power.
Prerequisite: Character Level 10, Must have eaten the flesh of a Devil or Demon
Benefit: You gain the ability to cast one spell from the Half-Fiend template per day as a spell-like ability (limited by your HD on the Half-fiend chart). In addition, all spells from the Evil Domain are considered spells known for you, you gain a +2 to Intimidate checks, and you can choose to count as a Tanari or Baazetu for the effects of spells, magic items, or prerequisites for feats or prestige classes.
