School of Astromancy

Astromancers use techniques inspired by the heavenly bodies to strike their foes. You bend spells, be it yours or others', to suit your needs.

Wanderer

When you select this school, beginning at 2nd level, you know where true north is at all times. You also gain proficiency in cartographer's and navigator's tools. Additionally, you gain the ability to create star charts. At night, if you can see the sky and stars, as part of a short or long rest, you can make a star chart, mapping out the celestial bodies from where you are. If you have two or more star charts, you can determine when and where the star charts were made relative to each other, regardless of who made the charts.

Astrodynamics

Starting at 2nd level, you can manipulate your spells' range and trajectory. When you cast a damaging single-target or area of effect spell, you can extend its range by half its maximum range. Additionally, you can bend your spells' path, avoiding creatures and terrain, ignoring cover, in order to reach its intended target. You can use this feature equal to your highest spell slot. You regain all uses of this feature after finishing a long rest.

Stargazer

Starting at 6th level, you can siphon a spell's power and cast it later. Whenever you cast a spell, see one cast, or negate the effects of one, if you have the spell slot corresponding to that spell's level, you can copy it and cast it later without using a spell slot. Negating spells includes casting Counterspell of Dispel Magic. Copied spells ignore class restrictions, and are lost after an hour. Once you use this feature, you must finish a short or long rest before you can use it again.

Spell Conduit

Beginning at 10th level, whenever you cast a spell, if it affects an area of effect or creature, you can cast spells as though you were in the affected creature or area's space. Once an area of creature has been used, it cannot be used again until it is affected by another spell you cast that didn't use this feature. This effect lasts a minute after casting the initial spell.

Supernova

Starting at 14th level, you can use a large portion of your magic reserves at once. When you cast a wizard spell, if you still have spell slots at the level used to cast it, you can spend all spell slots to cast copies of that spell at once, equal to the number of remaining spell slots. You can also do the same when using the Stargazer feature. You can do this for each spell slot level. You regain all uses of this feature after a long rest.
