Firearms Adept

You have firearms training that allows you to perform special trick shots. You gain the following benefits:

• You learn two trick shots of your choice from among those available to the Gunslinger archetype in the fighter class. If a trick shot you use requires your target to make a saving throw to resist the trick shot's effects, the saving throw DC equals 8 + your proficiency bonus + your Dexterity modifier.
• You gain 3 grit points. 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. This grit is used to fuel your trick shots.
