Ninja Exam 75 as water main with out using Gnw Kiba lol instead you need itachi. Reason why i picked itachi
Well he gives ignite debuff for 3 turns + he has change of avoiding enemies attacks. Thought this combo might need bit luck but for me it worked pretty nicely. Just make sure that your hinata survives so she c*ed to seal kakuzu's skills but any way here is my line up for this one. While doing this my lvl was 57

Ninjaa exam 81-84 Team used Iruka Gnw Tentetn Itachi and WAter main

Line up Itachi/GnwTenten/iruka
Nothing/Watermain/ Wm clone

Skill set 2/3/1/2/1 with White snake summon

1st turn just interupt 1 of those big fellows at back row
2nd turn just combo those big boys and avoid using itachi's mystery it just messes things up lol
3rd turn gnw tenten mystery to deal massive dmg
and after that just repeat
