The Fighting Monks of the Order of Wen (History Monks) guard history from those who seek to destroy it. Quite literally in fact. They guide history along its path & try to prevent evildoers from breaking or stopping time. They aren't always successful, so they also put history back together from time to time. 

Time Manipulation

You learn to slow down time around you. Starting at 3rd level, you can spend 1 ki point to gain an extra bonus action or extra reaction that lasts until the beginning of your next turn. You may only use the extra bonus actions to make an unarmed strike, Patient Defense, or Step of the Wind. You can only use this feature once per turn during your action. If you're unable to take actions or reactions, you may not use this feature. 

At 6th level, spend 3 ki points for 2 extra bonus actions/ reactions

At 11th level, spend 5 ki points for 3 extra bonus actions/ reactions

At 17th level, spend 7 ki points for 4 extra bonus actions/ reactions

Time Slice

Starting at 6th level, you gain the ability to move in smaller and smaller fractions of time. On each of your turns you can use a bonus action to move up to twice of your unarmoured movement bonus without provoking opportunity attacks. 

Deja Fu

By 11th level, you have mastered Deja Fu, the martial art that allows practitioner to travel in time as well as space. You can go back in time and hit your opponent with a series of punches. From the opponent's point of view, the practitioner is standing motionless, but the opponent feels the effects from the past attacks. 

As a reaction to a creature making an attack roll within 5 feet of you, you can expend 1 to 5 ki points to strike the attacker. You can make a number of unarmed attacks against the creature equal to the number of ki points spent. The Stunning Strike is automatically applied to the last successful attack without spending additional ki.

Way of the Yeti

You have learned how to save your progress in life. Beginning at 17th level, you can spend 8 ki points as an action to create a save point. Record your current hit points and conditions affecting you. You teleport back to this point in an hour. When you teleport, you replace your current hit points and conditions with the recorded ones. You must finish a long rest before you can use this feature again. If you died during this hour, you return to the saved point alive and you can't use this feature again for 7 days.

History Monk

You begin developing a limited foreknowledge.Starting at 6th level, you gain expertise in History. You also learn the guidance & resistance cantrips.
