Galaxy Magic

Your magic comes from the void of space itself. You might have been born just as an ancient star died, or perhaps you came across a fallen comet and were transformed by the power inside it. These sorcerers often hear a call from the void, feeling a strange kinship with the night sky, and the urge to take their place with amongst the stars above.

Arcane Orbit

At 1st level, the sheer weight of your magic has its own gravitational pull. Once on each of your turns, you can capture an object you can see within 15 feet of you that weighs a number of pounds equal to your sorcerer level x 5 or less and isn't being worn or carried. The object begins a lazy orbit around you, following you in your space as you move, which lasts until you release it (no action required).

You can exert fine control on objects within your orbit, such as manipulating a simple tool or pouring the contents from a vial. You can't use your orbit to attack or activate magic items. You can hold a number of objects in your orbit at a time equal to your Charisma modifier (minimum of 1). Additionally, you learn the missile cantrip, which doesn't count against your number of sorcerer cantrips known. When you cast missile, you can propel any object in your orbit.

Untethered

Also at 1st level, you can escape the tethers binding you to the earth. You have a flying speed equal to your base walking speed. You can't fly more than a foot above the ground using this feature, and you slowly fall if you are above that height, taking no damage from the fall.

Asteroid Belt

Starting at 6th level, you can use your bonus action and spend 2 sorcery points to form a belt of debris using your orbit. For 1 minute, any damage except psychic damage you take is reduced by the number of objects in your orbit.

Additionally, when a creature misses you or a creature within 15 feet of you with a ranged weapon attack, you can capture the projectile in your orbit (no action required).

Lost in Space

By 14th level, you are unbound. Your flying speed can carry you to any height, and you can hover.

Additionally, you no longer need to eat, drink, or breathe, you do not age, nor can you suffer the effects of any ability or effects that would cause you to age, and you can survive in the vacuum of space.

Gravitational Burst

When you reach 18th level, your ability to manipulate space and gravity reaches its apex, allowing you to channel its power with ease. As an action, you can expend 6 or more sorcery points to forcefully eject any number of objects in your orbit as though you had cast the Catapult spell on them at 2nd level. This casting ignores the weight restrictions usually applied to the catapulted objects. For every sorcery point beyond 6 that you spend, the level of the catapult spell increases by 1.
