Both she and Matt should have checked before this but now that she had things became clear.
Mana concentration was useful in and of itself, but the main reasons that any mage put essence into it were the residual effects of increasing maximum mana and mana regeneration speeds as well. If they didn’t put essence into mana concentration, the essence in the other two sections wouldn’t be as effective, after a point.
The returns would eventually get so bad that a mage without mana concentration cultivation would have weaker mana than a mage with less regeneration and a smaller maximum pool. The spirit needed mana concentration to allow for stable growth.
But with Matt, that wasn’t a problem. He just needed enough mana concentration to hit harder than a pillow. Luna made that seem like a hug
