OP Summoning!

A man sat cross-legged on the stage as he listened to the teachings. 

Normally anyone would have laughed at such a fool. Learn a skill? He'd be better climbing a Tower to be awarded some! But none here would ever dare to underestimate the founder. 

They simply followed the lesson along with Josh, summons flooding the stage and flying around him as he tried to get a feel for it. 

"Sir, do you sense this? This is the magical "wavelength" that I use to summon. But for you it won't be the same one. You have to find one that fits you…." 

"I see…" 

Summoning was akin to manually changing the radio channel until something finally reacted…if there were infinite possibilities and only one active station! 

It was definitely a waste of time! — or so most people would have agreed. 

"Get a feel for it, get a feel for it." He kept repeating as she kept summoning while chugging mana potions.
