(Race)
Your innate ability to shroud others in darkness is further empowered.
Prerequisites
Fiendish Darkness, darkness spell-like ability,
Caster Level 3rd,
Tiefling.
Benefit
You gain a +2 bonus to your effective caster level when using your
Darkness spell-like ability. In addition, whenever you cast a spell with the evil descriptor that targets another creature, you can spend a
Swift Action to apply the effects of your
Darkness spell-like ability to the spell cast, with the
Darkness effect centered on the spell's target. Using the
Darkness spell-like ability in this way expends all three uses of it for the day, and it cannot be used if fewer than three uses of it remain for that day.
