Feat: Return to the Pit!
You can send the fiends who have vexed you back to their home plane where they belong. You can cast Banishment once per day as a divine innate spell. When you take this feat, you craft a personal symbol of the Hellbreakers League that's anathema to devils. If you wield this symbol in one hand when you spend an extra action while casting banishment on a devil, you don't need to pay the extra cost to give that creature a –2 circumstance penalty to its save.
