Following are the Trick Shot variants for the Gunslinger class.
Golden Bullet. As part of your attack, you fire a trick shot that strikes your target in a vulnerable gap in its armor. Choose a creature you can see that is within your weapon’s normal range, and make a ranged attack against that creature. This attack ignores damage resistances.
Piercing Shot. This trick shot does not modify a single shot. Instead, as an action, you fire a trick shot that passes through multiple targets. Your shot is a line 5 feet wide extending from you to your weapon’s normal range in a direction you choose. Creatures in the line must succeed on a Dexterity saving throw or take damage equal to your weapon’s damage.
Pinning Shot. As part of your attack, you fire a trick shot that forces your enemies to take cover. When you use this trick shot, choose a creature you can see that is within your weapon’s normal range, and make a ranged attack against that creature. If the attack hits, the target must succeed on a Wisdom saving throw or be knocked prone and become frightened until the start of your next turn.
Ricochet Shot. As part of your attack, you fire a trick shot that ricochets off of stone, metal, or a similarly hard surface. When you use this trick shot, if you are aware of a creature in total cover, you can target it if there is a clear path for the bullet to travel along.
Wounding Shot. As part of your attack, you fire a trick shot that leaves your target bleeding or venting vital fluids. When you use this trick shot, choose a creature you can see that is within your weapon’s normal range, and make a ranged attack against that creature. If the attack hits, the creature must succeed on a Constitution saving throw or take additional damage equal to your Dexterity modifier (minimum 1) at of each of its turns. This effect lasts until a creature makes a successful DC 10 Wisdom (Medicine) check to bind the wound or until the creature receives healing. The damage dealt by this trick shot is cumulative with additional wounding shots. This trick shot works on living creatures and steamjacks but has no effect on other constructs or the undead. Trick Shots save DC = 8 + your proficiency bonus + your Dexterity modifier.
Special Trick Shots (Gained from classes)
Return Fire. When a creature targets you with a ranged attack, before it makes the attack roll, you can use your reaction to make a ranged attack against the creature. If your attack deals damage, the creature makes its ranged attack roll with disadvantage.
Snipe. As part of an attack, when you attack a creature beyond normal range, you do not have disadvantage on the attack roll.
Dual Shot. You can use your Trick Shots feature to fire two bullets in quick succession. Once per turn, as a part of the same Attack action, you can perform an additional attack against the same target.
