As an adept Marksmen, you've learned to perform powerful trick shots to disable or damage your opponents using your firearms.

• You learn two trick shots of your choice, which are detailed under “Trick Shots” below. Many maneuvers enhance an attack in some way. Each use of a trick shot must be declared before the attack roll is made, and trick shots can only be fired if the required grit is expended. You can use only one trick shot per attack. 

• Grit. You gain a number of grit points equal to your Wisdom modifier (minimum of 1). You regain 1 expended grit point each time you roll a 20 on the d20 roll for an attack with a firearm, or deal a killing blow with a firearm to a creature of significant threat (DM’s discretion). You regain all expended grit points after a short or long rest.
