Just saying Water main is not that great for next few exams so if you are up for switching Earth/Fire/Light can do them all few k power earlier with minimal rares. I would not recommend trying under 35k as Water unless you don't mind restarts.

2 Talents with Ninja Dog Shiba, Dog of Hell works as well.

Turn 1 - Lee and Hinata mystery, from now on spam them every time they are up, Hinata MUST start combo with normal attack and immobilize Jiraya, yeh a lot of retries yey.

Jiraya has to die here or go into next round with less then 5% life to die from 1 poison stack.

Turn 2 - Main mystery on Zabuza.

Turn 3 - Guy mystery on Kakashi, do it after enemy water main healed to leave extra poison stack for 5% more damage if you can.

Turn 4 - Main mystery on Kakashi, after this turn only water main should be left alive and you won if you got to this part.
