Thanks so much for the water stratagy for 85, helped me get through it fairly quickly.
For 86 water mains, there's some rng involved and poison was the main thing i was using to kill people, but hopefully this helps;
3* Kankuro is the imporantant thing, and there might be a better placement for Tobi
Focus on the other three first, otherwise their attack will get too high for you to last. Be as strategic as possible with your heals, and with using Kankuro's skill. Resummoning his puppet saved me several times, and I ended up with only a few hundard health myself. Way faster to do this as a fire main, but I'd just switched back from that so this is *ternative.
