that passive does not work on clones, tested thyself

From what I heard, it doesn't count clones; it counts the 4 units in your line-up only. Look on the bright side: at least Hidan does something else other than killing himself now.

Although, has anyone try this passive in rank battle/GNW yet? Does it count all 12 ninjas in your field?

so Arena prowess is useless

So if you use something like Sarutobi Hidan and Jigokudo you can basically keep getting buffed 20%?

As always, Oasis * at explaining stuff...when it says team, sometimes it works for whole field, when it says team (the same word) without additional word, it means only 4 players...they should learn how to write the differences between the two, if it's whole field, it should be written whole field, it is only partially written for some ninjas, but mostly it says just "team" and you can go and * your head against the wall trying to figure out if it means whole field or just your 4 ninja team...

It count all 12 ninjas

Every times a unit in the field is defeated (both teams), his Ninjutsu and Attack will be increased by 12 %. It's a powerful passive skill if there are more than 4 enemies or there are some ninjas can resurrect (both teams)
