Unnerving Aim
When you hit a creature with a ranged weapon attack, the target must succeed on a DC 13 Wisdom saving throw or become Frightened of you until the end of your next turn.
A creature Frightened in this way cannot willingly move closer to you during its next turn.
One Against Many
When you hit a creature while at least two hostile creatures are within 10 feet of each other, all hostile creatures within 10 feet of you that can see you have Disadvantage on their next attack roll against you made before the start of your next turn.
You can use this feature a number of times equal to your Proficiency Bonus, and you regain all expended uses when you finish a Short or Long Rest.
No Hesitation
When you hit a Frightened creature with a ranged weapon attack, you can move it up to 10 feet from its current position.
This movement does not provoke Opportunity Attacks.
