What to teach?

After telling them the insane amount of 2-star mana art available, Sir Trevor asked, "So What do you guys think 3-star mana art is?"

Elie said from the middle section, "Sir, I think if we add one more core art, then the combination of 3 core arts will be 3-star mana art."

Sir smiled, "Well, this may sound simple, but the complexity and versatility of 3-star mana arts are in a different league than 2-star mana arts. Just to give you an idea, let me tell you there are only 156 mana art within the academy library."

Silence!

For a moment, he thought he heard it wrong. One guy even asked, "Sir, did you say 156 thousand?" 

"Nope, only one hundred and fifty-six." 

"What that low" 

"Why so low?" 

"Is 3-star mana art tough?" 

"There are such a few options for us…" 

Chaos started, everyone started asking multiple things, and some even started complaining.

Sir taped on the stage. 

Tak Tak!
