Firearm Adept

You have firearm training that allows you to perform special trickshots. You gain the following benefits:

• Starting when you choose this archetype at 3rd level, you gain proficiency with firearms, allowing you to add your proficiency bonus to attacks made with firearms.
• You learn one trickshot of your choice from among those available to the Gunslinger archetype in the fighter class. If a trickshot you use requires your target to make a saving throw to resist the maneuver's effects, the saving throw DC equals 8 + your proficiency bonus + your Dexterity modifier.
• You gain 2 grit points. A grit point is expended when you use it. 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.
