Wizard Arcane Tradition: School of Astronomy
The School of Astronomy studies the patterns of the stars and the movements of the planets. Wizards of the school often sit on the extremes of intrepid explorer or reclusive sage, their training enabling them to draw upon stellar energies to empower their spellcasting and summon creatures of starlight.
Astronomer's Profciencies
2nd-level Astronomy feature
You gain proficiency with navigator’s tools, which you may use as an arcane focus for your wizard spells, and you also gain proficiency in the Survival skill.
Astral Manifestation
2nd-level Astronomy feature
You can focus your power into a cosmic entity of pure starlight. As an action, you may expend a wizard spell slot, conjuring your cosmic entity in an unoccupied space you can see within 30 feet of you. When you conjure it, the cosmic entity gains a number of temporary hit points equal to three times the level of the spell slot expended.
The cosmic entity is friendly to you and ambivalent towards your companions, and it obeys your commands. You determine the creature’s appearance, such as a humanoid or bestial silhouette whose joints shine with interconnected lights, or a swirling nebula with miniature suns for eyes.
The cosmic entity shares your initiative count in combat, but takes its turn immediately after yours. On its turn, it can only take the Dodge action unless you used a bonus action on your turn to command it to Dash, Disengage, Help, Hide, or to take one of the actions from its stat block.
The cosmic entity lasts for 1 hour, until you use this feature again, or it is reduced to 0 hit points. You may use this feature once, and you regain all uses of this feature when you complete a short or long rest.

Celestial Alignment
6th-level Astronomy feature
Your studies of cosmic geometry allow you to capitalise on perfectly lined-up shots. When you target a single creature with a spell, you may choose to apply the same effects of the spell to one creature of your choice within 5ft of the target. If the spell requires a saving throw, both creatures roll independently; similarly, if the spell requires an attack roll, you must make two separate attack rolls.
Birth Sign
10th-level Astronomy feature
You can draw upon different constellations to empower your cosmic entity. When you summon the entity, you may choose one of the following constellations to empower it in a unique way. You may choose a different constellation each time you conjure it. Consider altering the appearance of your cosmic entity to reflect this constellation.
- The Archer. The cosmic entity’s Solar Flare action gains a range of 30 feet.
- The Bear. The cosmic entity’s maximum hit points are calculated using five times your wizard level, instead of three.
- The Chalice. The cosmic entity gains the following action: Cup of Life (once per short or long rest). The cosmic entity touches a willing creature, suffering necrotic damage up to your wizard level and restoring that many hit points to the creature. The damage the entity takes cannot be reduced or deflected in any way.
- The Mountain. The cosmic entity’s base size increases to Large, and it gains advantage on Strength checks and saving throws.
- The Looking Glass. The cosmic entity gains Telepathy out to 30 feet, and can see invisible creatures and objects within the same radius.
Stellar Motes
14th-level Astronomy feature
Your attunement to cosmic magic surrounds you with small motes of starlight. You gain a maximum number of motes equal to your Intelligence modifier, which hover closely about your person. By default, the motes shine brightly, and you may choose to dim or brighten them as a bonus action, and you may choose whether to affect all the motes or just some in this way. The motes must be shining for you to use them. Once you have expended a mote, you must complete a long rest to gain it back.
You shed bright light in a radius equal to 5 feet times the number of shining motes, and dim light for an equal radius beyond that. When you damage a creature with a wizard spell, or as a reaction when your cosmic entity damages a creature, you may expend a single mote to deal additional radiant damage to that creature equal to 1d10 + your Intelligence modifier. Alternatively, you may expend a mote as a reaction when you are targeted with an attack roll, causing it to flash brightly, imposing disadvantage on the attack roll and all future attack rolls against you until the start of your next turn.
