Attribute energy is something that existed inside every Arcana master. However, not everyone could bring it out. Stats say that only one in every ten thousand Arcana master can have the talent to bring it out.
But, what's the truth?
Well, ninety nine percent of those Arcana Masters who could do it were all experts that reached Rank-7.
Inadvertently, one can say that those who reached Rank-7 has 99% chance of extracting the attribute energy from their cells.
However, this theory also applies to those who lived longer than the longest ever lived mortal (at least 200 years). The longer one lives, the more they could extract the attribute energy.
For someone like Avia, who was only 44, it is already amazing that she possessed the talent to extract the attribute energy from her body. But, her lack of experience made it tough for her to keep extract the attribute energy and use it in battles.
