Imagine making soup.
Yes, I mean the one you eat!
The perfect brew is made by adding several diverse ingredients to form a perfect blend of varying items. These opposing flavors come together as they complement each other, forming a delicious harmony.
The same can be said for Fusion.
Mixing mana of varying kinds together to achieve a more powerful result… wasn't that just the epitome of mastery?
Just as it took great skill and time to achieve a desirable mix of ingredients when cooking the ultimate soup, arriving at Fusion took an equal— if not greater amount of ability. As a result, it was hard enough for a Mage to mix his/her Mana with a Familiar.
Yet, this man in front of me could Fuse with a thousand Familiars… and right before my eyes, he combined his Mana with five separate Familiars.
'This man… is most certainly the most skilled Magic User I have ever seen!'
