Which Primals do you want to see?

[SuzakuCMX]

They each govern 3 elements, hence the 33%, and yes, increasing potency in xxx element will help with Banish or Scourge depending. I pimped out Fire potency so my Banish is consistently stronger than my Scourge, but not by a ton because it's only using 33% of that.

No, they each govern all 6 elements. Statwise they each govern 3 elements.
