One, how the fucking fuck do you create a barrier that can only be dispelled by something that just happens to cure the very opposite of magic itself? That's garbage writing. Wahl didn't even analyze the barrier to see if it had a rule. What he did was do the same exact thing he made his proxy do to get into Magnolia, which was nullify magical barrier particles. The very fact that Wahl was had is complete nonsense as well, because if anything, if I was in that situation, I would have been like, "Okay, I'll just beat you death my robot fists," which is about as effective as anything else he could do because of how sick Laxus is/was.

And two, I said explosive/blood, because I have no way of knowing what it is without the raw. Therefore, I listed it as being either because of this. And the question is, where and how did Laxus get the ability to conjure percussive lightning? Please enlighten me. This is all out of nowhere.

And about Gajeel? Torafuzar simply had skin that was made of a composite that was weaker than steel. If it had been Erza fighting him, she would have had the complete advantage because her swords are made of steel, but it wasn't her, so an illusion as to how tough his skin was had to be made.
