Way of Momentum

Momentum Monks often become adventurers, heisters and bounty hunters for the thrill of the chase. Additionally, these monks find themselves right at home in any bustling city. 

Speedster's Technique

When you pick this tradition at 3rd level, you learn to bend speed itself. As a free action, you can spend up to three ki points to add 5 feet of movement to your movement speed per ki point spent. If you do this, you need to move an amount equal to the feet of movement you got from this ability, or this effect ends. If you move equal to the speed you get from this ability, you get to add an extra Martial Art die to the attack.

Tireless

At 3rd level, you can ignore the ki point cost for Step of the Wind a number of times equal to your proficiency bonus, every short rest. 

Steamroller

At 6th level, if you move 15 feet or more at an enemy, you can take an action to make a CON save against their DEX. If you succeed,they are prone and take bludgeoning damage equal to one roll of your Martial Arts Die plus your proficiency bonus. If you fail, they take half the damage rolled.

Momentous Strides

At 11th level, you can, if you move at least 15 feet or more, run across any flat surface, including water and ceilings, if you don't keep moving after you use this, you fall.

Rushing Advance

At 17th level, you can spend as many ki points as you want to add 10 feet of movement per ki point to your movement speed. If you run in a straight line, you can add 30 feet more to your movement. All creatures you run into are treated as difficult terrain and are knocked prone. You don't trigger opportunity attacks when you do this.
