What increases combat power the most?

Used for upgrading active and passive skills an d you can get them from event packages or rare mine shop.

I don't know about the event but you can farm itachis secret at 21-4

Use/get hanzo he does lots of damage

You can get them at 20-5

Train your kabuto

You should also get a thousand sharks kisame to weaken the narutos, that's how I got pass 20-1

Thank you

I farmed it and it wasn't too bad, didn't take very long

Ok thank you

I'm pretty sure if your trading material ninja has a pill equipped you can't use it for material

I'm in the same boat as you
