A strange accident has left you changed forever. Struck by lightning and affected by harsh toxins and chemicals, your body now has access to the extra planar dimension of speed. Your connection to this plane gives you unrivaled speed and new powers that stem from your new connection to this speed realm.

Speedster

Beginning at 3rd level, you gain the following effects.

You may use your Step of the Wind feature a number of times equal to your Wisdom modifier without expending a ki point. You regain those uses when you finish a long rest.

The effect of becoming a Speedster also results in your body needing more energy to keep up with your speed use. When you eat, you need to consume twice as much as normal to feel sustained.

Quick Reflexes

Beginning at 3rd level, your lightning-quick reflexes give you advantage on initiative rolls.

Enhanced Body

Beginning at 6th level, you've begun to resonate with the frequency of the molecules around you, and gain the following benefit. You can phase through solid objects with your incredible speed. You can use 10ft of your movement to pass through a 1ft thick solid object. This scales up linearly, so passing through a 5ft solid wall would take up 50ft of your movement. If you stop your turn in the middle of a solid object you take 8d8 force damage and will continue to do so on the end of each of your turns that you stay phased into a solid object. 

In addition, you also gain resistance to Lightning damage.

Pure Speed

Beginning at 11th level, you've begun to harness your inner speed and gain the following benefits.

You may spend 5 ki points and a bonus action and enter a state of pure speed for 1 minute, gaining the following:
-You are under the effects of the haste spell (no concentration required)
-During this state, your punches are fueled by the speed that drives you. You may add an additional d4 lightning damage to your unarmed strikes that you make.

You gain one use of this feature, and must finish a long rest before you may use it again.

Improved Flurry of Blows

Beginning at 11th level, when you use a ki point to trigger your Flurry of Blows, you can use your bonus action to make 3 unarmed strikes, instead of 2. However, all 3 strikes must be on the same target, in succession, with no movement used in between.

You still have the option of using Flurry of Blows in the standard way as well.

Into the Fold

Beginning at 17th level, you've begun to embrace your presence in the Speed Force. Spending 10 ki points and using your action, you can bring yourself into the plane of speed. You receive the effects of the Time Stop spell. This ability can only be used once before needing a long rest.
