As a model student who had never skipped a single class, Reese's mind raced, and he immediately recalled the contents of Theory of Circle Tiers and Spell Mana Consumption.

A mage's total mana was directly tied to their Wisdom points.
Roughly speaking, it could basically be understood as equivalent to their Wisdom stat.

With a mage around level 30 having a mana pool of barely over a hundred at most, they could only fire off four or five [Lightning Bolts] in one go!
