Graviton Knigt

Wielding the terrifying powers of gravity, utilizing it both in and out of combat, the graviton knight is a force to behold should one ever be faced on the battlefield.

A graviton knight utilizes a very specific branch of magic known as graviturgy. Such a knight can use it to buff their weapons, bolster their bodies and influence the world around themselves.

Force of a Comet

When you learn this form of magic at 3rd level you gain access to the gravitational powers of a comet. You gain access to the following features:

Gravity points: you have a pool of gravity points equal to your CON modifier plus your proficiency bonus. These are used to buff your graviturgy. You get your graviturgy points back on a short rest.

 Mass influence:
You gain the ability to influence the mass and velocity of your weapons and yourself.
Costing a gravity point you may charge your weapon with gravity magic. choose one of the options below:

1. Charged Range: ranged weapon double their range
2. Charged Melee: melee weapons deal double damage to structures or an extra 1d6 points of force damage (has to be put on the weapon before rolling attack)

In addition you may influence your own body in a variety of ways, these cost no gravity points but may be buffed costing said points:

1. Gravity jump: you double your jump height, if you spend a gravity point the height and length is instead quadrupled
2. Gravity rush: you spend one gravity point, gaining the ability to take the dash action as a bonus action
3. Gravity Lift: you exert gravityrgy onto whatever object you are holding. Any check you make for the next 10 minutes to hold up or lift an object that is below 10 counts as a 10.

Graviational influence: 
As an action you may exert gravitational influence over an object that weighs no more than 100lbs that is within 60ft, you may exceed this weight limit by spending gravity points, increasing the weight with 50lbs per point. you may move said object 30 feet per round, this can not be used to attack but can be used to open a container or door, pour a liquid or similar things.

Meteor throw: by spending a gravity point, you launch an object within 60 feet towards an enemy, the object deals 4d8 physicals damage (depending on the object). 

Pull of a Moon

At 10th level you have learned how to influence larger bodies and even other creatures as you have gained the influence of a moon. 

Your gravitational influence can now be used on creatures that are large or smaller. The range of this influence is 60 feet costing you one graviturgy point. You may increase the size to huge by spending 4 graviturgy points. Creatures can be moved 30 feet per round and take 1d12 bludgeoning damage when impacting surfaces. When using this ability the creature may make a strength saving throw against your save DC = Strength+proficiency+8. Every time the creature takes damage and at the end of its turn it may attempt to break free.
