I wish I could help y'all but I am not having any issues with this event other power scaling. Got up to 34 before I was unable to beat it. I am running a team of FM, 6P Naruto, Jonin Minato and Kisame Fusion Mode. I just focus on the top group till they are wiped then go after the bottom team. Talents in case those wondering are Illusion, Bomb Blast, Burning Ash, Genjutsu, and Oboro Cclone. Gamaken as summon.
