@321zigzag1: what protects erza is not the armor itself. it a magical barrier that the armor casts. anyways erza's equip is extremely verstile not to mention she has more stamina and could eventualy outlast byakuya.
she can summon other weapons at the same time you know? she often mixes her armors. either you know little about FT or you just have read about it.
What magical barrier? She has shield thing that forms in front of her but even if it does, it doesn't change what I said, a gate can't win by offense. I don't recall the barrier in the manga actually.
Strange question to ask, because when was the last time she switched her armors or weapons? Weapons I could understand maybe but armors?
Even the Fairy Wiki editor in this thread admitted not remembering when Erza switched. Knightwalker switched weapons but one at atime. Erza switched armor and weapons but one at a time.
Have you ever seen her use adamantine armor with otherthings? No. Have you ever seen her use Heaven's Wheel with other armor and weapons? No.
Kagura vs Erza should tell you that Erza switched not mixed if I recall.
Erza vs Ikaruga should tell you Erza switched not mixed if I recall.
Erza has great offense to put Byakuya down for sure and Isuppose one can argue on nakagami armor but I am not too sure how that wouldapply technically, perhaps you can tell me.
