As for the other flow state—Overload, it was kind of the opposite of Overdrive in how it worked, and it required even higher control of Mana than in Overdrive.
In simple terms, it was basically chugging a Mana potion while still having full Mana in one's Mana pool.
With exceedingly excess Mana in one's Mana pool, the mana would become volatile, and it could severely injure them as well.
But as long as one retained control, the Mana would turn violet from blue, increasing in potency by 100%!
Suppose Almond had a capacity of 5000 mana, and he added 5000 More before trying to enter Flow State—Overload and even succeeded.
That would make his skills and whatever moves he used that consumed this 10,000 violet and violently potent Mana in his Mana pool extremely powerful!
Overdrive strained one's body, making them exhausted after usage, and requiring 24 hours before using it again.
