Sorcerous Origin: Wish

Wish is the most powerful spell that can ever be cast. The fabric of reality itself bends to the will of the caster. Sometimes, a wish has unintended consequences, sometimes the wish happens not as expected or intended. Sometimes the wish works exactly as intended. To make a wish is to create a destiny. 

Sorcerers created from wish origins, are made by the purest form of magic. They are a product of the raw altering of reality. Perhaps they are the wish, created to fulfill a desire. Maybe they are an unintended consequence of a wish gone awry. Possibly a lowly peasant wished upon a star or djinn and the fabric of reality altered to accommodate his desire. As a wish sorcerer you must always stride towards fulfilling destiny. 

No matter their creation all wish sorcerers are created from pure magic and as a result are more in tune with magic than any other. It is always certain that, wishes must be fulfilled and destiny must be followed. 

A Touch of Destiny

 You were created by magic and are considered a magical being. Starting at level 1 as a result of your closeness with magic and destiny you can shape magic to your whim, and fulfill minor desires. Prestidigitation is added to your prepared spells and does not count against spells known. 

Thief of Fate

At level 6 your closeness with magic allows you to change a spells intended target.  Once a day you can steal a beneficial spell from a target and place it randomly on you or your nearest ally. Roll a d4 if the result is even you gain the effects of the beneficial spell, if its odd your ally gains the spell instead. In the event allies are equal distance you may choose which one may receive the effect. The spell last until concentration stops from the original caster or for the specified time limit of the spell. 

 

Magic Mirror

 At level 14 due to your connection with magic, you can feel spells on a deep level within your being. On a reaction you may spend a sorcery point to reflect a cast spell  within 120 ft of you back at the origin of the spell or, a new target within the spells original range. This has no effect on already cast spells. 

Cosmic Wish

You were created from a wish and understand its function better than any. Wish is added to your prepared spells and doesn't count against your spells known. If you already learned wish it does not replace it. Additionally you have advantage on the random chance of never using wish again if it is used for any other effects aside from a level 8 or below spell effect.
