Way of Deadly Speed

Focused on going fast, and dealing damage based on that speed you have attained.  This Subclass lets you speed up to incredible amounts, letting you out-speed most enemies and even your allies to escape that hellish boss monster your DM threw at you out of nowhere.

Level 3: Increase Speed

At Level 3, Level 6, Level 11, and Level 17, Increase your base speed by 10ft.

Level 3: Strike of Speed

For every 50ft you move in a turn, you may deal an extra 1d6 damage on the first attack you make that turn after your movement.  Your movement is only counted if it is after a 90 degree or more turn.  This means you can make turns that total 90 degrees (two 45 degree turns), but they must not be made too quickly, or else you loose your speed.

Level 6: Air Step

Once per turn per 5 levels (rounded down), you may expend 1 Ki Point to make an Athletics (Strength) check to jump mid-air.  This could allow you to jump far enough to get across a cavern your normally couldn't, or get enough height to attack that flying enemy just out of reach of your normal jump.  You may also spend 3 Ki Points as a Reaction to cast Feather Fall on yourself.

Level 11: Incredible Swiftness

As an action, you may cast Haste on yourself by expending 5 Ki Points.  While under the effects of Haste from this ability, you may, once per activation of the Haste effect, take the Dodge Action as a Bonus Action without expending a Ki Point.

Level 17: Deadly Weapon Rush

Once per long rest, you may expend 8 Ki Points to have all of your attacks for 1 round be affected by your Strike of Speed ability, allowing you to strike with incredibly deadly force.  At the end of the turn you use this ability, you gain 2 levels of Exhaustion.
