Sort Of f2p Exam 119 guide - I havent donated a cent, I do have some rare ninjas though.

Power is 36.9k

Lineup:
x------------------x-----------------x
WB Asuma-----Main--------------x
Mei---------------x----------------Ao

Summon - Hell dog.
Talents: 3,3,4,2,1

First round has to be perfect:
you have got to reflect blind either on Konan or Main - if no - restart
You have to control minato with AO ult - if no - restart
You have to control Konan or main (the one that does not have the blind on) with fire ult - if no - restart

Round two:
Asuma on Main
Round three:
Mei on Main
Round 4:
Main and konan should be dead
Ao on minato, main on minato (if you miss - chances are you will have to restart)
Round 5: everything you got on animal path - you can auto here on forward

I know its a hassle, but all the guides I have seen involve Sage naruto and like 42k+ power

Hope this helps
