Way of Lightning

Monks of the Way of Lightning do not necessarily wield literal powers of electricity, but instead figuratively embody it through explosive speed. They hone all parts of their body to perfectly move as quickly as possible, not only can their legs carry them across deserts and above mountains in mere seconds, but they can throw out attacks at a nearly blinding pace. Their speed typically manifests due to some form of extraplanar power, perhaps it appears as streaks of lightning emerging from you, trails of fire from your feet, a beam of light from your back, sketches of yourself predetermining your actions, or maybe you really are just that fast.

Lightning Fast

When you choose this tradition at 3rd level you can use your Step of the Wind feature without expending a ki point. You can also use your Flurry of Blows feature without expending a ki point. You gain the following ki features:

• Step of Lightning. You can spend 1 ki point to triple your speed until the end of your turn. Your movement also does not provoke opportunity attacks for the rest of your turn. At 11th level you instead quadruple your speed.
• Storm of Blows. As part of the bonus action used in your Flurry of Blows feature spend any number of ki points. Make a number of additional unarmed strikes equal to the amount of ki points you expended. At 11th level you instead make additional unarmed strikes for every ki point you expend.
• Speedster's Deftness. As a bonus action spend 1 ki point to re-roll a Dexterity check you made after you roll but before you know the result. At 11th level, this becomes a reaction to failing a Dexterity check.

Momentum

When you reach 6th level, you learn to take advantage of the momentum gained from your speed. The damage of the first unarmed strike you make after moving in a straight line towards a creature is increased depending on how far you moved, 1 roll of your martial arts die for 60 feet, 2 for 120 feet, 3 for 240, and 4 for 480, adding another 1 roll for every 2000 feet beyond that. You also gain the following ki features:

• Forward Movement. You can spend 1 ki point as an action to continue building up your speed. If you do this, your base movement speed becomes half of however far you last moved in a straight line this turn until the end of your next turn. For example, if you moved 200 feet in a straight line, your base movement speed becomes 100 feet. If you fall under the effect of something that doubles your movement speed, such as a haste spell and a dash action within the span of your next turn, you can move 200 feet.

Speed Blitz

When you reach 11th level, your speed becomes nearly impossible to see. Whenever you move at least 480 feet in one round you become invisible until the start of your next turn. A creature with any sense beyond normal sight, such as truesight, blindsight, or tremorsense is still affected by this invisibility, but a creature with a passive perception 5 points higher than your dexterity score is not affected by this invisibility.

Godspeed

When you reach 17th level, you have mastered the art of movement. You can use an action and expend 3 ki points to cast haste on yourself, without the need for verbal, somatic, or material components. Whenever you are under the effects of the haste spell you also gain an additional bonus action and an additional reaction, and can use an action to expend 4 ki points to cast freedom of movement on yourself without the need for verbal, somatic, or material components.
