The Way of the Energy Fist has trained extensively in the natural energies of life force and has learned to manipulate them to certain extents. Able to wrap their hands and feet in a physical manifestation of energy penetrating their enemies' defenses and perhaps even wearing down on the energy of their enemies.

Energy Blades

A cloak of pure vibrating energy surrounds your unarmed strikes allowing them to become magical attacks and do either piercing or slashing damage using 1d6 + dex to determine damage. This energy vibrates with power and speed that is able to penetrate an opponent's body by piercing or slashing. This effect can be activated as a bonus action, lasts 10 minutes, and can be used once freely per long rest.

Each additional time this ability is used before a long rest and after the first one, the energetic draw slowly threatens to sap your life force. Any uses beyond the first result in a DC 15 constitution saving throw, on a success nothing happens, on a failure you take 1d6 necrotic damage.

This damage increases to 1d6+dex+PB at level 6, 1d8+dex mod+ PB at level 11, and 1d10+dex mod+PB at level 17.

Energy Presence

Your Connection to natural energy allows you to be hyper aware of your surroundings granting advantage to initiative rolls, and Pecreption and insight checks on Sentient Organisms within 60 feet. 

Energy Dam

Able to sense Energy flow hot beds in the body you can spend 2 Ki points to Dam the flow and grant disadvantage on ability checks and attack rolls until the next round. Overcharging this ability allows you to spend 4 Ki points to grant the victim of this ability 1 level of exhaustion for 1 minute.

Energetic Overflow

Opening all the energetic dams in your own body, as a bonus action you can double your speed, increase all ability scores by a +2 modifier, this can bring those scores over 20, and allow your energy blades to last for the duration of this ability. This lasts 10 minutes. You can end this effect at will without expending an action or bonus action, if this ability is allowed to end of its own accord the user must make a DC 20 constitution check, on a failure the user suffers 2 levels of exhaustion that last for 2 days or until restored by a greater restoration spell. This ability also grants the user the Spider Climb spell for the 10 minute duration of the feature as pools of energy allow your feet to adhere naturally to all surfaces including liquid surfaces.
