I can clear Strong approach hard mode with f2p ninjas with Fire main.. I'm lvl 75 too.

Fire 4*
Kabuto 3*
Kimimaro 3*
Tayuya 2*

All fully cultivated and kimimaro / tayuya are the only gold awakened... check there's a strategy guide around for fire main. This post was last edited by Ryonell at 2016-10-16 12:41
