as i don't have any good healer to use for my dark formation, i think that i'll pick andromeda as soul for this event.
wanted to use mordred at first so i can have a nice combo of black propaganda+satan skills, but then i don't have healer nor def buff to my team, so if she strike hard my team may get wiped out.
or...i can use arc, cut damage for her overdrive attack and her regeneration may help my team to survive, i remember that in dullahan event, a kami that got beaten from death instant could revive with the effect of regeneration lol.
though now i'll have to either pick sniper shot to reduce damage and hit harder or black propaganda so along satan's skill it'll take her longer to use her overdrive attack.
