Heh I had tried her too and still got walloped. I waited to recharge my command spells to do the trick (I categorically refuse to use my SQs!) but eventually easily clobbered the fool right back with someone's fully levelled Orion. It was purely down to the luck of the draw with my getting enough of Orion's arts/buster cards, which is exactly what I had needed with
@Vincentdante's Heracles but hadn't been as lucky then heh. The gacha effect comes into actual gameplay as well! But yeah, he was very annoying to have to fight, so many times as well, the jammy git.
