Granblue Fantasy Relink : Gallanza & Maglielle, Solo Narmaya, No deaths, No potions

Fight was a bit tough, but I found out I just have to wait for an opening which is more tedious than difficult. Once one opponent is down, the fight is basically over. Did still get a little reckless at the end though...
I'd highly recommend any +invincibility time sigils, because without them it will be extremely difficult to gather butterflies and use her abilities at full potential.
