Spell Experimentation

Your study of the arcane has led you to experiment with your spells in the hopes of creating something new.  

As an action, you can combine two spells to create a new spell. this costs two spell slots to do. in addition, you must make a DC 10 + the levels of the two spells, Arcana Check. on a success, you cast the new spell, which is added to your spell book. on a fail, you make a roll on the wild magic table. 

The new spell can't be at a higher level than the highest spell chosen in the combination. you may customise the new spell based on the two spells you used to create it. The spells used must be from the Wizard spell list.
