Replicate (Izzet League)

"But then...oh, but...which means...which would lead to...exactly!"

Your involvement with the League has awakened your explosive nature! If one is good, more is better!

Whenever you cast a spell and consume a spell slot to do so, you may also expend any number of other spell slots of the same level to copy the cast spell that many times. 

For example: If you cast Guiding Bolt with a 1st level spell slot, you can expend all other 1st level spell slots to copy Guiding Bolt that many times.
