Common, Uncommon, Rare

Emily pressed a button on her watch. A large picture was then projected on the whiteboard. It had five words that said, 'Common, Uncommon, Rare Magic' in bold.

"Can anyone give a few examples of common magic?" Emily asked.

A few students raised their hands, others were quietly using their watches, and Marcus had his right hand below his chin.

"You" Emily pointed to one of the students.

A girl with short hair a black hair tied into a ponytail stood up and said "Fire magic, water magic, and earth magic"

Emily nodded."You are correct. Although they are common magic that doesn't mean they are weaker compared to other magics. Especially if you advance in them or if you find a good magic book that can turn them from common magic to uncommon magic, and even to rare magic. Can anyone give me an example of this?"

A few hands were once again raised. Most of them were the same people who raised their hands last time.
