Trying to take these down by attacking them from the ground wasn't going to work. The best and easiest way was to let my fallen gods be hit first, then in the middle of the attack they'd start retaliating.
It was risky indeed, given that these star weapons looked a bit more powerful than the ones I dealt with before.
But I got enough souls to replenish what was lost. And with the thousand and half fallen gods here, I was sure to destroy lots of these star weapons in a short time.
"Go out, wreak havoc on these zombies to draw their attention," after watching them consume my stat crystals and getting stronger, I added, "once getting attacked, use your ultimatum to hit them back… Go now and may luck be on your side."
I watched them fly over and scattered all over the grand place. As they left, they started attacking the zombies, killing lots of them in no time.
