Disciple of Darkness

Lawful evil alignment,

Once per day, while performing an evil act, you can call upon your diabolic patron to add a +1 luck bonus to any one attack roll, saving throw, ability check, skill check, or level check.

This feat can only be taken once. A character who takes this feat cannot also take the Scion of Sorrow or Thrall to Demon feat.

You formally supplicate yourself to an archdevil. In return for this obedience, you gain a small measure of the archdevil’s power.
