Fanning Specialist

You've developed a mastery over firearms that allows you to fire with extreme swiftness. As an action while you have no cover, if you are within 30 feet of your target, you can fan the hammer of your revolver (pepperbox or exandria pistol). When you do so, you make a number of shots up to the remaining rounds in your firearm, each with a -5 to the attack roll (up to a maximum of 6 shots). This feature takes up your entire turn; you cannot take another action/bonus action to do anything until the beginning of your next turn.  Spells that apply extra damage or effects on your attacks only affect the first attack roll you hit with this feat. Once you make this action, you cannot do so again until after you finish a long rest.

Prerequisite: Must be Proficient with Firearms before taking this feature.
