Elemental Affinity

"And an elemental affinity with [Comprehension]... I need that…"

When Mathias realized that there was an Elemental affinity crystal that was being auctioned, there was no way for him to calm down.

This was even more apparent when he realized that it was an [Comprehension] Elemental affinity. They were extremely rare and thus very expensive. 

Many Originals would pay a lot for an [Comprehension] Elemental affinity because the affinity's strength would always be strong as long as one had a high enough understanding of the ability.

For Mathias, whose Innate ability was [Elemental Comprehension], Elemental affinities with the [Comprehension] tag were the most important. His strength would elevate manifold the moment he bound a new affinity to his mana core and he would continuously become stronger the more affinities he got his hands on.
