Monks who follow the Way of the Black Hole have spent significant time meditating on the universal force of gravity. With their deep understanding, they are able to focus their ki through large gauntlets in order to manipulate the gravity of themselves and their immediate surroundings.

Gravity Gauntlets

Starting when you choose this tradition at 3rd level, you can use large gauntlets that act as a conduit to harness gravitational force. The gauntlets are considered both monk weapons and unarmed strikes. When wearing them, new Ki features are available to you.

• Singularity Strike
  Using Step of the Wind to dash allows you to add extra force damage to the first successful attack with your gauntlets on your turn, equal to your Wisdom modifier. You can also deal 1d10 extra force damage for each ki point you spend when you make the attack. The maximum amount of ki points you can spend is equal to half your monk level.
• Density Shift
  You can spend 1 ki point as an action to touch a target that is large or smaller and either double or half its weight.
• Stellar Slam
  Once per turn, when you hit a creature with your gauntlets as one of the attacks granted by your Flurry of Blows, the creature must succeed a Strength saving throw or be pulled to the ground and knocked prone.

Dark Star Drop

At 6th level, you can spend 3 ki points to strike the ground with your gauntlets as an action. Creatures within 10 feet of you must make a Strength saving throw. On a failed save, a creature takes force damage equal to your Martial Arts die, is knocked prone, and is pulled within 5 feet of you. On a successful saving throw, the creature is unaffected and takes half damage. 
If the attack is made after falling on your turn, any damage reduced by your Slow Fall feature is added to the force damage of the attack

Mass Manipulation

Beginning at 11th level, when you move up a vertical surface with your Unarmored Movement feature you do not fall if you stop moving. You can also move upside down on ceilings as if you were affected by the Spider Climb spell.
Additionally, Strength saving throws made to resist being knocked prone are made with advantage and you are not affected by the Reverse Gravity spell unless you choose to be.

Event Horizon

Starting at 17th level, you can spend 5 ki points and create a small black hole by smashing your gauntlets together. Any creature within a 10 foot cone in front of you must make a Strength saving throw and are pulled into the black hole on a failed save. On a successful saving throw, the creature suffers from one level of exhaustion, representing the physical strain from resisting the pull. You can use this feature again after a long rest.
