Quick Draw

You are Fast with you guns and you gain a few abilities.

• You gain advantage on all initiative checks. You on the first turn of combat have advantage on attack rolls against any creature
• When an enemy moves within 10 feet of you, you gain a reaction to make an opportunity of attack against them with your gun that you are wielding or in your holster. If the attack hits then the creature speed becomes 0 for the rest of the turn. You can use of this feature for a total of your (Dex mod + Pro. bonus), you regain all expended uses of this feature after a short or long rest.

 

Trick Shots

You have learned to put your bullets on point with deadly accuracy. Whenever you would an attack on your mark with your sneak attack ability, you may also apply a Trick Shot (See Trick Shot section below) to the attack. You have a total of (Dex mod + Pro. bonus) to use this feature and you regain all expended uses of it when you finish a short or long rest.

Trick Shots
-Crippling Shot: This shot will cause the targets to have disadvantage to all it's rolls and any damage it might do is halved until the end of your next turn.
-Gut Shot: Your well placed shot staggers the target, and its movement speed becomes 0 until the end of its next turn.
-Finger Breaker: With this trick you shoot the hand of your target.  When your bullet hits the hand your your target, it heavily damages the hand, stopping them from casting spells with Somatic components. Shooting their hand will also force them to drop an item that they are holding with that hand to the floor, until the end of their next turn.

The Showdown

You may use your action to make a single ranged attack against a number of targets you can see equal to half your level (rounded down). Each target must make a dex saving throw vs your showdown save DC (10 + your proficiency bonus + your Dex modifier), and each target greater than 30 feet away takes an additional 2d8 bonus damage. This can be used once per encounter.  If any of the targets pass they move 5 feet back and take no damage from your bullets.

Important Notice: If you do this when you are hidden they roll at disadvantage. (The same could be said for when your target is busy fighting someone else but ask you DM, she/he has final say.)

The Last Shot

When an attack would reduce you to 0 hit points, you can use your reaction to delay that damage, and immediately make a single attack against the attacker with advantage. This attack applies your sneak attack damage even if you have already made a sneak attack this turn. If you still have a Trick Shot available it is possible to reduce the damage you would taken from the initial shot.  For example with finger breaker or crippling shot, however if you fail to prevent the damage, you will still take damage from the original attack even if your attack kills your assailant.
Once you use this feature you can use it again until you finish a long rest.
