At 2nd level a number of Small balls of light that look like Stars orbit you. The number of Stars you have are equal to your intelligence moddifier + half your wizard level, rounded down (minimum 1). Once per round as a free action, when you cast a spell you can expend Stars to grant the spell you're casting an additional effect based on Astronomcial Objects.. Effects are listed in the table bellow. All expended Stars return after completing a Long rest. If you are knocked unconcious any currently active effects disappear immediately.

At 2nd level, you learn the Light and Dancing Lights cantrips if you don't already know them. Additionally, you have advantage on Intelligence or Wisdom checks related to checks about information about the Cosmos. If the night sky is visible you always know where true North is.

This is my moddification of a space-themed Wizard Subclass by reddit user groggen22. This moddification seeks to remove the RNG component of the spell buffs via adding a resource system. This is the very first draft of this subclass.

Cosmic Conscious

At 6th level you gain 60 feet of darkvision. Once per short rest you can project your conciousness into the stars and look downwards. You can see everything within a 50 feet area around you, provided it is visible to the sky.

Chaos Theory

at 10th level, once per long rest if a creature you can see rolls a 1 or 20 on an attack role, you can invoke your Cosmic Connections feature on them or the creature they're targeting.

Big Bang

at 14th level once per long rest as a bonus action you can expend 5 Stars to enhance the damage of the next Cantrip or spell cast. Any damage it will do is Maximized.

Alternative Features

The following are other ideas I have for features which may subsitute the existing ones.

Big Bang

At 14th level when you’re knocked unconscious, 1d10 Random creatures within 30 feet of you are afflicted by a random Cosmic Connections effect. Roll 1d10 for the effect.

Overview Effect

At 14th level as an action you can distribute your Stars to creatures you see within 60 feet. You transfer any amount of Stars you have to creatures within range. While these creatures have these stars, they can telepathically communicate to you or any creature who has your Stars. Once per Round they can expend Stars to invoke effects from the Cosmic Connections table when they cast a Spell or when they hit a weapon attack. All unexpended Stars return to you if you or the creature holding them are knocked unconcious or if 1 minute passes. You can use this feature once per long rest.
