>>3370286All right, I finished S rank enough times to complete the challenge. For the 10 Zetsus, I try to keep my units far apart so each Zetsu can only hit one of my units. If any Zetsu hits two then it's probably over. One shot from green Madara's secret tech wipes them, so using a max dupe friend unit and then pushing all the Zetsus towards him with my first two attacks gets most of them try to attack him, which usually gets him enough chakra by his first turn. I haven't tried it with green-only, but since it's a third turn kill the Zetsus only get one round of attacks so it should still work. Although HP might be a little low for the second screen since I believe you have to contend with a one-turn ninjutsu from Obito which can hit multiple targets.
I've also finished SS rank at last! It took like 2 hours. Even the second screen takes half an hour, how many defense buffs is he gonna stack? Third screen is extremely long and scary when trying to get healing up without being in his range. His secret tech hits for 5k per target and can hit multiple targets so I need to make sure only one unit is within his range and also that my passive healing is up when he does it. It also gives him 10 turns of +10,000 HP and he uses it every 8 turns so sealing his HP recovery is mandatory. On top of that only two elements can even damage him and his ninjutsu and secret tech determine which one is more effective. Compared to last week's Empty Spectacle, The End of Salvation is a lot harder but I think figuring out how to do it was also more interesting.
Half stamina and triple exp were really useful, I could challenge all the Super Impacts and it would just level me up and restore all my chakra. Now I can only do a limited number. Having to wait to try a mission again is a bit annoying, especially when I've come up with a strategy I want to try.
