Bladeback Blue sounded like some herb but it was actually a type of mineral. It looked like metal on the outside but its inner part was blue; the darker it's color, the better it's quality.
Black oil mineral was just like its name suggested, a type of black oily mineral.
Kieran skillfully crushed the two minerals and mixed them together according to the ratio. He then started to draw the required magic circle on the ground: a triangle enveloping a square in the middle.
The triangle was the base and the square inside was the advance plus conversion. Then, Kieran used the diamonds to draw a similar magic circle on the wolves as well.
Finally, the wolves with the magic circle drawn on them would walk into the magic circle on the ground.
As the spell was activated, two magic circles would resonate and [Brand. Strengthen Fur] would be complete.
