quite frankly, my 5 girls in my sig are all waiting on blooms (aside from sakura) so they all add to my setup...

they already get a rather large atk increase (about 70%-100%), but all bosses take a 1.05 damage multiplier and raid bosses face all this and an extra 35% atk boost to my team...

but when some blooms come in, i'll start getting SB increases, atk increases from SB, more skill rate (i think it hits double at that point), and 3 girls (iberis always being one of them) will be dual element each fight (doing extra damage to both magic and striking weakness).

that's honestly quite a massive set of abilities when you think about it. which already includes someone dodging (lycoris) and someone doing counters (helenium)
