all buffs stack. If you have doubts about abilities stacking or who they stack on, just look at the little buff symbols appearing at the beginning of battle. When you are not sure bring a friend, battle some kakashi clones and watch those little buff animations!

I know the shields stack, that much is obvious, you can visibly see the shields apply.
The extra statistics part of the passive however is a bit harder to test. I was hoping to hear others experiences.

it should, konan who is the akatsuki version of bee will stack her buff

Konan's buffs do not stack but her shields do. Killer Bee, havent paid much attention even though we run 2-3 in GNW, will run some tests later unless someone else has already.

he stacks:P thats why ppl in china make teams with bee's and roshi combined do a lot;P

What have you been smoking?? Konan's buff stacks if you have multiple Konans, like killer bee, Great ninja war Ino or any ninja that has a passive that uses a number in its description. If an abillity says it will buff 6 ninjas it will buff 6 ninjas and if you have multiple ninjas with the same passive they all apply. Now, on the off chance you have tested multiple Konans and only one applies buffs, then its a very much a huge bug and it needs to be reported immediately.

What have I been smoking obviously the right things, cuz her buffs don't stack it's been tested and proven by countless others and myself.

yeah, i really think that the buffs should totally not stack in between teams, because that way you'd just get 3 exact teams like this: NARUTO SAGE MODE, KILLER BEE, 1ST hokage, WIND MAIN 2 of the teams in gnw, and 1 team with onoki instead of 1ST hokage(just to buff all narutos 40%), and you'd just have 2 teams with naruto buffed to...well let's do the math 90%(killer bees), 60% Hashiramas, 40% onoki, and 40% from wind main, that's a total of 240% buffs(so you got 340% of the initial stats, so a 10k nn would transform in a 34k nn, good luck dealing with that)...that ain't right, you'd basically just 1 shot entire teams

fck, i just remembered that gaara(kazekage) is entirely superior in terms of damage to naruto, so 3 kazekage gaaras will most likely 1 shot the entire enemy in GNW(sincerly i rather think that 2 are enough but...) This post was last edited by 122***@facebook at 2017-3-8 09:40

it stack dude, that why akatsuki or jinchuriki team is very good in group fight lol :lol:lol

Same passives NEVER stack. (eg. Asuma WB and Earth Main pose of duel)
It's same for Killer B. Whether you have 1 or 3 of them, the buff will still be 30%.

I've tested it myself.

Yes same passives stacks.. Have u tried leech passive from LM or Guy?

IT DIDNT STACK, the only thing that stack was the shields, for example buff like mifune konan or killer bee didnt stack, of course there is some exeption like ligtning anbu or guy's leech or SB leech, GO TEST it out on ur own before saying anything

The damage portion of buffs like these do not stack. The shields however do.
