The Mass of Eating Melon Seeds

I was reincarnated into another world, and I brought the Horadric Cube from Diablo II with me. 
Being a knight is cool and all, but being a wizard is pretty neat as well.
So, which one will it be?
  

Abe the Wizard

"Sir, I'm telling the truth. I was just accepted into the Yveline Magic Tower four days ago."

As Abel tried his best not to let any blame go to Sam, he tried to be honest as he could to the wizard in front of him.

"Did you learn the 'fireball' spell in just four days?" the wizard asked, and Abel kept nodding his head."

The wizard seemed to be reminded of something, "You haven't met the Wizard of Yveline yet, have you?"

At least the wizard was starting to ask about something else. Abel began to sigh in relief. The wizard was putting too much pressure on him.

"Show me your 'fireball' here," the wizard said.

"Here?" Abel looked around him. He was just told that spells were not allowed in the city.

"Yes, right here!" the wizard laughed and then said, 'I'm not leaving any time soon. You'll be fine.'

So, What Now?
