I was going to make a video of it when I did it on my account at just under 42k but I used Sage Naruto 4* so I'm not sure how f2p friendly that is. I did it with Earth main lvl 83 41.7k BP earth main in front with 2nd mystery and shield generator auto and pose of duel and steel body. Had sage Naruto behind main and Onoki behind Naruto to interrupt Ningendo with autos along with 5 kage temari under everyone to be shielded by narutos clone. Takes a little RNG but you want to focus Gakido because he holds the combos together, Jigokudo doesn't do anything so focus Gakido and the RNG you need will be based off of having your Naruto clone survive because if hes up Shurado will always mystery the clone. If anyone else gets hit by shurados mystery just restart that thing hurts too much.
