Hey guys!

Overall it's the same thing, but Y increases enemy chakra (only by 10 but it could be useful sometimes)

Go with the +2 if you want more damage, Y for a more supportive style

Y is the preferred one because of the cooldown reduction, you only lose the 30% damage bonus

A chakra battery passive

+2 is definitely better in my opinion, giving your team some chakra and more defense (only weaker vs ninjutsu I guess)

Some tanky clones and increased healing for the team

Breakthrough priority:

Mystery, Passive 3 > Standard Attack > Passive 1, Passive 2

Overall he could be a useful ninja as a chakra battery considering he's quite f2p friendly

But there are tons of other better replacements for him so I just made some f2p based teams here

1. Fire Main

2. Fire Main 2

3. Wind Main
