Group skills are way too low - I'm lvl 69 with 20k+ power, but I have all my group skills maxed to 35.

I have to say that group skills are the biggest contributor to overall battle power.

Also, getting at least 2 of your ninjas to 4 stars will also be beneficial to increasing BP.

Whenever I increase one of the main group skills, such as HP, attack, nin, def and resist, my BP jumps up by at least 30-40, so it's a significant amount when you compare it to strengthening equipment.

Joining a top group is very vital in getting stronger tbh.

You should definitely focus more on refining since the refining event is currently active so exploit the crap out of it as much as possible.

Refining does help in increasing overall BP as well as give you an edge in fights, so yes, if that is your only available option, go for it.

Every failed attempt gives you 1 blessing, and the ac*ulated blessing points give you a higher success chance the next time you try to refine the same weapon/armor piece. This post was last edited by Godsu* at 2016-9-23 06:16

Hinata can cause acupuncture via combos, so if you're able to target a specific ninja that's about to cast and are able to go first, then you can pretty much interrupt their cast plus apply acupuncture to the said ninja.

Neji is purely for control purposes and cannot be relied on as a suitable tank if you compare him with Hinata and Kimi.
Also, regarding refining, you're going to need ALOT more than 5 runes to bump one piece of gear, I'm afraid, event or not. :(

I'm just saying that the chances of a successful refine are more high during this event.

Oh, yeah, it took me a numerous amount of tries before RNGesus granted me that W.

Also, I used a Hinata, Kankuro, Sasuke, and MC to beat the 80 exam, so hopefully that helps. If you want more insight on the specifics, just ask.

I'm still trying to find out the screenshot for the team I beat 80 exam with. Once I do, I'll let you know.
