Although in the case of most warrior-nobles, their houses each had unique mana technique and had no reason to learn such a basic mana technique, but in the case of scholar-nobles and sons of powerful families that aren’t nobles, they needed the foundational mana technique that would strengthen their basics.
 * 1) Vasis Mana Technique was in fact the most basic mana technique that one learned when attending academy knight school in the Byron Kingdom.
 * 2) Batelein Mana Technique in the Rinse Kingdom
 * 3) Datio Mana Technique in the Istel Kingdom

But it was a mana technique in words only, and grasping the mana hole and moving the mana through the mana road was the all of this basic mana technique.

‘There’s also Datio Mana Technique.’

Roan also picked up the Istel Kingdom’s basic mana technique compilation that was next to the Vasis Mana Technique.
