Way of Speed

Very Fast

Unnatural speed

Hyperactive speed. You can use any number of ki points at the start of your turn to increase your speed by 10ft for 1 minute or until you end a turn without moving. This effect stacks, so spending 2 ki points increases your speed by 20ft and so on.

Unstoppable speed. You can spend a ki point to cast Freedom of Movement as a bonus action on yourself for 1 minute or until you end a turn without moving.

Heightened Senses

Also at 3rd level you gain advantage on all acrobatic checks to avoid being grappled and advantage on Dexterity saving throws against effects you can see such as traps and spells. To gain this benefit, you can't be blinded, deafened, or incapacitated. 

You may also add 1 d10 to your initiative rolls as well as your Wisdom modifier

And your movement speed also increases by 20 ft

Relentless Speed

When you use your bonus action to use Step of the Wind, you gain the benefits of both the Dash and Disengage action instead of having to choose.

Additionally whilst under the effects of step of the wind you have advantage on all attack rolls.

Regenerative speed

Starting at 11th level your body's superior kinetic functions to regenerate wounds. As a bonus action you can expend up to 5 Ki points to heal yourself. For every Ki point you invest you may heal 2d6. Using this feature will also remove the blinded and deafened conditions so long as the source is not longer affecting you.

Ki Rush

Also at 11th level, you can enter a period of slowed time.

There are 2 ways to utilize this slowed time.

You may use your action and 4 Ki points to enter this state. While in this state you are, unaffected by difficult terrain and can use falling terrain and liquids as platforms to walk on. You may also pick up and use objects if they are light enough as a free action. As a bonus action you can roll your martial arts dice an equal amount of times to your monk level and distribute that damage among any enemies you can reach using your movement speed. After finishing this attack gain 1 point of exhaustion. Exhaustion points earned in this way are compounding, therefore the next time you use this ability before a long rest gain 2 points of exhaustion (3 total), using again will gain 3 (6 total) at which point you will die from exhaustion.

Alternatively you can use your reaction and 2 Ki points whenever a creature within 50 ft of you fails a Dexterity saving throw to let them succeed. You must make a Dexterity saving throw against the same effect in their place however you do not receive the benefits of your Heightened Senses or Evasion Features. If the effect has a radius (such as fireball) you must move them and yourself to the edge of the radius. If you have no Ki points remaining you can use this feature but you automatically fail the saving throw

Godlike speed

Starting at 17th level you move with godlike speed. You can use 2 reactions per turn and your movement speed also increases by 20ft.

Speed beyond Time

As well at 17th level you can move your body beyond the limits of time itself. You may use your action to run in a straight line for at least 88ft attempting to send your soul into the past. Make a Dexterity Saving throw DC 20. On a fail you are knocked prone 100ft in a straight line from your starting position and take 5d10 force damage.On a success your soul is sent to the past.

The time moved back is equal to your total movement speed converted into minutes. Only you are aware of your travel back in time and your soul will re-appear in your body from the past. Therefore your level, health, ki points and equipment at that point are that of the past self and not the future self.

The effect this has on your body is so immense that it causes it to fall into dust. Make a Constitution saving throw DC 25 to try and maintain your physical form. On a failed save your body is disintegrated after 1 minute (nothing can prevent this). You and everything you are wearing/carrying, except magic items, are reduced to a pile of fine grey dust. You can be restored to life only by means of a true resurrection or a wish spell.
