Consume the Enemy (Su)

As a full-round action that is considered an evil act and provokes attacks of opportunity, you can bite a helpless living or freshly killed creature, dealing 1d3 points of damage. By consuming the creature's flesh, you gain a +1 profane bonus on saving throw DCs for all spells, spell-like abilities, and supernatural abilities you use against creatures of the same type (and subtype, if humanoid or outsider) as the cannibalized creature. This effect lasts for a number of minutes equal to 1/2 your cleric level or until you use this ability against a different creature.

At 5th, 10th, 15th, and 20th level, this bonus increases by 1 (+5 maximum). You can use this ability a number of times per day equal to 3 + your Wisdom modifier.
