Grit Point

You learn trick shots that enhance a firearm
attack in some way. You gain 2 grit points that
you regain after a short rest. You also regain 1
when you roll a 20 on firearm attacks or you deal
a killing blow to a significant threat (DM's discretion).
Your saving throws for trick shots have a DC of
8 + your proficiency bonus + your Dexterity
