Benefit(s): When you spend a swift action to attempt a performance combat check, you can sacrifice one cartridge or an amount of black powder required for a single shot to make either a loud sound or an impressive flash. If you choose to make your weapon’s report louder, you gain a +4 bonus on all Intimidate checks you attempt for 1 round. If you choose to create an impressive flash, you gain a +4 bonus on any Perform checks you attempt for 1 round.
