Are you seriously suggesting Melt is more powerful than the entire power of Tenrou Island?
Also please stop that was not Gildrats strongest attack. It was some magic that was stored in his arm.
Which is nowhere near this attack:
Also I pray to the heavens you aren't trying to claim that Gildarts attack was stronger than this:
Like's let's seriously cut the crap and actually look at feats shown. Outside of his sleep spell or Suicide Spell August doesn't have an attack that would take Erza Out or stop Erza.
1. Nakagami Armor can slice through Magic last time I checked. In the Manga no limitation was put on it so please stop with the Oh August magic is too strong for her to cut crap.
August can't nullify Erza Magic nor copy as a well known fact. Presented in the manga itself.
Present me with 1 spell August could use that he has shown outside of Sleep(Which is Mest Magic to make the mind follow an order), that could take Erza out that can be used in this battle.
