To realize the storm outside of you is nothing compared to the storm within yourself is the first step to releasing the power of the way of the tempest. Masters of this art will find themselves able to move through the battlefield with ease, striking like lightning and leaving their foes broken with blows that hit like thunder.

When taking lightning damage you can use your reaction to reduce the damage by your martial dice + WIS modifier and regain a Ki point.

Thundering Blows

Whenever you use your flurry of blows you may spend an additional Ki point to turn the damage into thunder damage and after taking this action you may move half your movement without provoking opportunity attacks

Into the Eye. Spending two ki points you pick any number of targets equal to or less than your wis modifier within 60 ft. of you, those targets must make a STR saving throw equal to your ki saving throw or be pulled into a unoccupied space within 5 ft. of you, any target pulled this way you may use your flurry of blows on.
