Thrall to Demon

Chaotic evil alignment,

Once per day, while performing an evil act, you can call upon your demonic 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 Disciple of Darkness or Scion of Sorrow feat.

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