You have struck a bargain with a fiend to gain power and can call upon its power.
Prerequisites
Make a pact with a fiend.
Benefit
You can draw upon the power of your pact to gain a +2 profane bonus to any one d20 roll. You must declare that you are using this ability before the roll is made.
You can use this ability twice per day plus one additional time for every other fiendish feat you possess.
Special
When you die, your soul belongs to the fiend who made the pact with you. You cannot be restored to life except by means of a miracle or wish. If you are resurrected, you permanently lose one level for each fiendish feat you possess. This level loss cannot be prevented.
