What do you mean by that?

Mood? His main attributes are ninjutsu/attack so a mood that maximizes one of those and minimizes something irrelevant.

mood xD mistakes were made

even if he's the tank?

I guess he could be tanky if ya boost his defense and who's ya Rayet-chan?

I use him in front of Kabuto; he's my best tank. Ideally I'd have a row like:

Kiba Akamaru Hinata

so the heat gets taken off Akamaru, but I'm surviving with my team right now.

what main are you using ?

I have fire main. You?

In regards to a mood, I would choose one of the following depending on what you need him more for.

+Life, -Ninjutsu
+Atk, -Ninjutsu

Kiba is mostly physical so you don't really need ninjutsu that much. Either life is he is your tank or atk if you have enough tanks on your team and need more damage.

I will say I haven't seen a mood for +Life, -Ninjutsu yet but still experimenting. I have seen the +Atk, -Ninjutsu (forgot what its called).
