Hey guys!

Not really f2p friendly but this is a really easy ninja exam if you have these 3 ninjas (also having these 3 ninjas makes all the other exams much easier too because they are simply strong)

Round 1: Wait for their standard attacks, use Earth Main mystery to gain chakra and then Kisame mystery

Round 2: Use GNW Madara mystery, Kisame if available

Rince and repeat
