Hi Oasis, i think your recommended power for ninja exams pass 120 is grossly wrong.
I have been stuck at lvl 123 and which has recommended power of 43468 but i am 45139 and still not able to clear it despite countless attempts.
I understand that formation and choice of ninjas are very important but still the health of the enemy and their dmg does not seem to be right.
I am sure I am not the only person struggling, maybe you can revise these figures so that players like me do not waste time until we get to a more appropriate power level.
