"We can see that the everyone is excited but all of you might be wary that these are fake. I, myself, might not be a great magician but I will try my best to show you that these rune stones are true." The announcer stated as he picked the Blazing Shield Rune Stone and inserted mana into it.
A flaming shield suddenly appeared in front of the announcer that surprised the crowd. They did not expect that the rune stoen was that great. The fact that the spell immediately activated when he just inserted some mana into it meant that it is of the highest quality.
The empty mana stones used to create them has the best sensitivity. A rune stone's quality can be divided into Poor, Mediocre, Average and High Quality. The fact that a small amount of mana can create such a reaction meant that the materials used are excellent.
