Disciple of Darkness

(Book of Vile Darkness, page 49, DnD 3.0)

[Vile]

The character formally supplicates himself to an archdevil. In return for this obedience, he gains a small measure of power.

Benefit

Once per day, while performing an evil act, the character may call upon his diabolic patron to add a +1 luck bonus on any one die roll.

Special

Once a character takes this feat, he may not take it again; he may not be the disciple of more than one devil. Nor may he take the "Thrall to Demon":feats/book-of-vile-darkness--37/thrall-to-demon--2907/ feat.
