Stellar Reading
Starting at 2nd level, you search for the stars in the inky black and use them as a sign of hope. When you cast a spell, a mote with a number of stars equal to the spell's level appear at a point within 60 feet of you.

When you cast a spell, you can choose to consume stars or produce more, but not both.

You learn to do a few things with these stars. The options are listed below.

Evaporate: When you cast a spell that deals damage at a mote or a target within 10 feet of a mote, you can consume any number of stars to deal an extra 1d4 damage.

Entropize: When you cast a spell that has a saving throw at a mote or a target within 10 feet of a mote, you can consume any number of stars to reduce one creature's saving throw caused by the spell by 1 for each star consumed. You can do this before or after they roll.

Star's Will
Starting at 6th level, the cosmos begin to show their true form. You gain a new mote option.

Align: When you cast a spell at a mote or a target within 10 feet of a mote, you can consume a number of stars equal to double a spell's level to cast that new spell as a bonus action. The spell must only target a creature within 10 feet of the same mote. This additional spell does not create new motes or stars but it can consume them.

Light in the Void
Starting at 10th level, you become resistant to radiant and necrotic damage.

Additionally, as an action, you can cause your motes to flare with energy. You can split motes into any number of stars and move each new mote to a point within 60 feet of you. The next time you consume stars, their efficacy is doubled; Evaporate deals an extra 2d4 damage per star, Entropize reduces the saving throw by 2 per star, and Align allows you to cast a spell with a level equal to the number of stars consumed rather than half.

Once you do this, you cannot do so again until you finish a short or long rest.

The Cosmic Definition
Starting at 14th level, you begin to understand parts of the universe that make yourself feel infinitessimally small. When you generate a mote with Stellar Reading, you can increase the number of stars in the generated mote or another mote within 60 feet by 1. You also can consume stars when choosing a target within 30 feet of a mote rather than 10 feet.
