Ultrakill

A fighter meant to move fast and shoot things.

Feedbacker

Starting at 3rd level you can use a reaction to parry nonmagical attacks. The attacks have certain properties. The attacks cannot:
* Be a critical roll
* Do damage equal to your hit points, or higher

When parrying an attack in this way you make a dexterity saving throw; the DC is equal to the roll to hit you. If you succesfully make the save then you, and the attacker, both take half damage from the attack.

Fast Movement

 Starting at 7th level your speed increases by 15ft, while not wearing heavy armor.

Speed Demon

Starting at 15th level, when you have to make a saving throw you can choose to make a dexterity saving throw instead. This ability can only be used once per long rest. You gain another use per long rest for this ability at 18th level.

Whiplash

Starting at 18th level you can expend an action to use the whiplash. The whiplash allows you to grapple a target creature within 60ft of you. This creature makes a dexterity saving throw that opposes your dexterity roll to hit. If they are larger than you, then you get pulled toward them. If they're smaller than you, then they get pulled towards you.

Knuckleblaster

Starting at 10th level your unarmed attack does 1d8 more force damage. At level 15 your unarmed attack also pushes the target of the attack 5ft away from you.
