Fusion magic II

"Last semester we focused a lot on arcane magic, this semester we will be focusing on fusion magic." 

"If you hear fusion magic and think about the fusion process, then you are correct." Professor Gibson said. "The fusion process fuses your elemental stars into one, while fusion magic is the process of using both elements at the same time to cast spells."

His words confused a lot of the students because wasn't this what they had been doing since the awakening test?

"I know what you are thinking, but being able to double or triple-cast doesn't mean you can use fusion magic." He immediately dispelled the confusion in their minds.

"Double casting is the ability to simultaneously cast different spells as separate entities, but fusion magic is casting spells of different elements as one entity." Gibson explained.

"Professor Gibson, can you please give us a demonstration?" Blake asked.
