「Granblue Fantasy」Tiamat Omega Aura (Impossible)

Fenie's weapon is perfect for this. Along with Manadiver you can basically increase the drop rate every turn. Full auto is a bit difficult especially during overdrive when she keeps spamming Veil and Mirror Image. Although with Mugen's weapon it could get really easy imo. Magna 3 is here and luckily they are not hard at all. Although they have so much HP so just sharing the room would be the best.
