I think your best bet is to cast Thundaga and summon Ramuh, hopefully the Attack node dies soon.
Luck has been cruel with me. It gives me 7 Ribbons from Dark Sages, 10 Minerva Bustiers, and 40 Artemis Arrows from Moongoddesses instead of an Artemis Bow :'(
I'm giving up on it, and I'm going to go for the Artemis Bow once I get on my third playthrough!
I've revised my whole Augment guide since I found a
fatal error in my plan, due to the fact that I got Rydia and Kain's augments mixed up

!
But I've found a solution to my problem! Revised yet again
I have two versions,
one for
Kain's Limit Break Adrenaline 3x Focus Darkness Jump, and one for
Rydia's Limit Break Adrenaline Dualcast Meteor!
Oh, both have
Twincast Adrenaline Limit Break Ultima!I think I can defeat Proto-Babil on my second playthrough, we'll see
