Jsk Way of Gravity

Gravity Strike
At 3rd level, your can wrap your blows with the pull of gravity. Your Flurry of Blows ability is improved.
 * When you hit two different creatures with the unarmed strikes granted by your Flurry of Blows ability during the same turn, you can choose to create a gravitational tether between the two creatures. Until the end of your next turn, the creatures cannot willingly move more than 15 feet away from each other, and cannot move if they are further than 15 feet away from each other unless they are moving closer to one another.
 * When you hit a single creature with both of the unarmed strikes granted by your Flurry of Blows, you can choose to envelop the target in gravitational energy. The creature's speed is halved until the start of your next turn.

Light as a Feather
At 3rd level, you can reduce your own gravity very briefly. When you're prone you can stand up by spending 5 feet of movement, instead of half of your speed.

Adjust Mass
At 6th level, you can influence the mass of a creature. You gain the following abilities.
 * Increase Mass: As a Reaction when you are moved against your will by an Effect, you can choose to not be moved instead.
 * Reduce Mass: You can spend 1 ki point to cast the Feather Fall spell without providing material components.

Fluctuate
At 11th level, when you use your Step of the Wind ability you also gain a flying speed equal to your walking speed until the end of the current turn. In addition, when you Effect a creature with your Gravity Strike feature it also takes force damage equal to one roll of your Martial Arts die.

Warp Gravity
At 17th level, when you hit a creature or object with an unarmed strike, you can spend 3 ki points to attempt to warp the directional pull of the gravity that is effecting it. If the creature is anchored to the ground or another solid surface, then the creature is not effected by this feature. Otherwise, the creature starts to fall in any direction of your choice. The creature must succeed on a Strength saving throw against your Ki Save DC. On a failed save, the creature falls up to 60 feet in the direction that you chose. On a successful save, it falls up to 30 feet in the direction that you chose. If a solid object is encountered in this fall, the creature collides with it just as it would during a normal fall. The creature's gravitational balance returns to normal after the fall, or after it collides with anything. You can only use this feature once per turn.
