So it seems peeps who made it to the final mission of chapter 8 is having a hard time getting it to 3 stars. It took some testing but this is the comp that I used to beat it easy. I will let you know now that iruka will die when you fight all the paines in the blue portal but that's the only death I had.
I showed my power as well so people can have an idea of what I had when I beat it. Mind you my iruka was only 2stars. The best thing about this comp is that you can auto the fights and be okay.
With my power I only lost Iruka but I had full health on everyone else. Earth main becomes so tanky they can't kill him. I would put a vid but I dont have any kind of program to do it plus since you can auto there isn't much to show.
If you guys have any questions feel free to ask!
