A monk that follows the Way of the Temporal Sentry draw power from the lingering strands of time itself. They use ki by channeling chronomantic leylines of possibility to create alternate timelines. Monks that dedicate themselves to this tradition learn about the flow of time, the positive and negative energies that come from it and its effects on others. By understanding this natural flow, monks are about to better understand there place in the greater scheme of the universe. 

Ephemeral Form

Your knowledge of the self within the timeline allows you to reach new heights of control. As a free action, you can enter your Ephemeral Form for 1 minute. During this time, you can use 1 ki point per turn without using your pool of ki points. If an ability or feature requires more than 1 ki point, you subtract 1 ki point from its cost.

You may use this feature a number of times equal to your proficiency bonus and regain all uses upon completing a long rest. 

Chrono Shunt

3rd-level Way of the Temporal Sentry feature

You learn a new way to use your ki incorporating your knowledge of chronomancy. As a bonus action, you can use1 ki point to warp the timeline, reversing your position back to your location at the start of your turn. When you use this ability, you do not provoke opportunity attacks and regain all of your movement for the turn. 

Continuum Split

11th-level Way of the Temporal Sentry feature

You learn to use the flow of time to hinder or enhance. You can spend 2 ki points to cast slow or haste on a creature without the need for verbal, somatic or material components. In the case that the spell requires a saving throw, use your ki saving throw DC. Both of these spells last 1 minute and require you to maintain concentration.

Ruminate

6th-level Way of the Temporal Sentry feature

You can draw from your own sense of reality to focus under pressure. As a reaction, you can spend 1 ki point to gain advantage on all concentration checks made until the end of your next turn.

Ephemeral Trance

11th-level Way of the Temporal Sentry feature

You learn how to enter a focused trance during your Ephemeral Form. When you enter your Ephemeral Form, you can spend 2 ki points to enter into an Ephemeral Trance. In addition to the Ephemeral Form benefits, this trance grants a number of benefits:
- You gain a +2 to your AC during the trance.
- Targets of your unarmed strike take an additional 1d4 force damage.
- You can target other creatures with your Chrono Shunt feature within 5 ft. If the creature is friendly and willing, the target is shunted to the location they started last turn, not provoking opportunity attacks. The friendly target can then use there reaction to move up to move up to there movement speed. If the creature is not friendly and willing, the target must make a wisdom saving throw against your ki saving throw DC, being unaffected on a success. On a failure, the creature is shunted back to the location they started last turn, taking 2 martial arts dice damage force damage from the force trauma.

This trance lasts as long as your Ephemeral Form and you must maintain concentration to stay within the Ephemeral Trance. You can end this trace at any time as a bonus action. If you lose concentration or end the trance, you return to your Ephemeral Form for the remainder of its duration.

Deja Vu

17th-level Way of the Temporal Sentry feature

You have honed your skills in harnessing the natural flow of time enough to reverse it. As an action, you can touch a creature within 5 ft. restoring the creatures body to its state before the last attack or spell that affected it. This returns its health back to the state before the attack or spell, removes any conditions that it caused or any spell effects that affected the creature. 

Once used, you cannot use this feature again until you finish a long rest.
