That's is what I mean, how Wendy had knowledge of that advanced level of enchantments, I understand that with the power of Irene body sh could cast any spell. If Eileen use her dragon magic with a single roar she can wipe out both Erza and Wendy due to the sheer amount of power she possess.

Exactly non of their attacks should be able to injure Eileen yet they do, that why I said that I'm disappointed.
