[GBF/グラブル] Light GW NM 150 Full Auto Premium Magna / 光 古戦場150hellフルオート 

M3 Katana is goated. Basically the plan is to just dispel the hell out of the boss. Clear time is subject to the dodge RNG so you may go around 15-30 secs slower. This was my best run so far. If you don't have Harmonias just replace it with Chev Swords, Astral, Celestial Sword, Horus Bows, etc.
Lucio's hard to replace cuz he acts as the main DPS and oh shit button. Closest one that I can think of tbh is H.Illnott for dmg and Zoi with her S4
G.Vira only one who can replace her really is Kubira but you don't have dispels.
S.Horus is replaceable with any other DPS you have like V.Aglo or dispellers like Grea, H.Mahira, etc.
