Off the top of my head, not mentioning what you already said:

Targets a Single Team:

Sannin War Jiraiya's Standard Attack

Animal Path's Standard Attack (targets 4 entities only, so idk if it really counts)

Edo Tensei Deidara's Standard (also targets 4 entities)

Sage Naruto's Mystery

GNW Tenten and regular Tenten's Mysteries

GNW Kankuro and regular Kankuro's Mysteries

Mu's Mystery

Akatsuchi's Damage Mystery

GNW Choji's Standard

Targets Multiple Teams:

Kazekage Gaara's Mystery (up to 9)

Tendo Pain's Mystery (all enemies)

GNW Choji's Mystery (up to 7 I think? maybe?)

Deidara's Mystery (can target multiple)

Konan's Mystery (I think? Never tested)

Zabuza's Mystery (I think)

I Don't Know:

Torune's Mystery (up to 9... never tested it)

Onoki's Mystery?

Tobirama's mystery (targets 12, since I don't have him never tested)

Sasuke Skillbroken Mystery (targets 12 units... never tested)

Also, Mei Terumi only hits 7 total characters, though spread out among all 3 enemy teams.

Since this is just from memory I might be wrong about some of this stuff. You may wish to double check the factuality of this.

Tobirama targets 1 unit and 11 randomly selected enemy units, spread across the 3 teams.

Consider there are also translation errors.

Lots of translation errors, that's why i asked for those who actually tested the ninja in real battle to know the real range of skills.

Sasori mystery is multi too

anyone knows about darui's barrier?

Darui buffs the 3 teams

If you want to know it you can go look at the chinese simulator and look at all the tooltips. If there's the specific ideographic symbol for field is field if there's the one for team is team and so on. There's no mistakes there xd.

1st post Updated with 20 more Ninjas AOE attributes.

100 puppets is randomly spread out amongst 3 teams, just tested it out

Minato-Single Team

Anyone with a sweep styled attack attack 3 people from the front row, middle if nobody's in front, and back if nobody's in middle or front.(That includes Chojuro, Danzo, WB Asuma, and more, from what I know)

Tobirama and Minato passives affect the entire team.

Konan, and Killer Bee's passive pick 9 people and buff them (I tested those two in ranked)

I can comfirm that Torune attacks 9 units on the enemy side, 8 random, 1 selected.

So, in all.

Minato-Single Mystery

100 Puppet Sasori-Multi Mystery

Minato-Multi Passive

Tobirama-Multi Passive

Torune-Multi Mystery (You mentioned it wasn't comfirmed)

Konan-Multi Passive (I use her on a different team then my Tendo in ranked, it still buffed him)

Killer Bee (7 Sworded Thug)-Multi Passive

Kinkaku-Single Mystery

Normal Gaara (3*)-Multi Mystery

Yugito-Single Mystery

Fukurokumaru-Multi Mystery

Sage Jiraiya-Single Mystery

GNW Temari-Single Mystery

Cheongsam Tenten-Single Mystery

Chojuro-Single Mystery

GNW Kiba-Single Mystery

Cee-Multi Mystery

Kiba-Single Mystery

Jugo-Single Mystery

Chikamatsu Chiyo-Single Mystery

Temari-Single mystery (second time.)

Naruto+1 -Single Mystery

Anko-Single Mystery (After Barrier is activated)

...Oh wait, I just noticed Minato and Sage Jiraiya.

Snap

Tanks for this big list, will add it to the 1st post.

Ah, I edited it just as you did that, if you need me to look into anyone else, I'll do it

If I have them

Thank you that will help for sure. (Edited first post, more structured)

Also, for the record.

Chojuro's standard attacks 3 enemies from the front row from any of the the 3 teams, so it's technically multi (Even if it's just one person on the bottom, still hits)

Chojuro's mystery attacks a single team, so a single mystery

Also, from what I've seen, Iruka effects only his team.

(Mainly observed from TI, summon, and gnw)

Big Update with all Current ninjas we have in the game, and a much "easy on the eyes" list, also added a "Missing Skills" section with all the remaining unconfirmed skills for those who might know the answer, any Contribution is appreciated.

I'll get to work on finding out the unknown ones.

(But seriously, Chojuro is 1)

Also, all the auto-barrier ninja (Such as Edo Haku, DAnzo, KAzekage Gaara, Darui, Mei, and Onoki) effect all teams.

Anko: Mystery (Barrier) = Single

Chojuro (Mist's 7 swordman): Mystery = Single

Choza Akimichi: Mystery = Single

Danzo Shimura: Passive = Multi

Haku: Mystery (Barrier) = Single

Guy: 1st Passive = Single

Guy: 2nd Passive = Single

Jirobo: Mystery (Barrier) = Single

Jugo: Passive = Single

Kakashi (Make Out Paradise): Passive = Single,

Kakuzu: Mystery = Single

Kakuzu: Passive = Single

Lee (8 Inner Gates): Mystery = Multi

Mifune: Passive = Multi

Obito (Shonen): Mystery = Multi

Onoki (3rd Tsuchikage): Passive = Multi

Sakura (GNW): 2nd Passive = Single, presuming you mean the quick healing, otherwise, just Sakura, if you mean reserve seal

Sasuke (Play Boy): Passive = Multi

Sasuke: Mystery (Barrier) = Single

Temari (Five Kage Summit): Mystery = Single

Temari (Five Kage Summit): 2nd Passive = Multi

Yamato: Mystery = Single

Taking care of all of these, will fill them out as a friend of mine helps me.

Also, I'm pretty sure Hokage buffs affect the entire field, I'll try to find another friend who has Hiruzen (Only 2 on my server atm)

Ty for these updates, for Sakura (GNW) i'm refering to her 2nd part of the 2nd passive, the one concerning her damage buff with number of summons, does she gain more damage from 1 lineup summons or all summons on her side of the field ? (same for Jiraiya (ero-senning), Kurotsuchi and Chojuro's passive skill effect)

I'm Sorry but the Lifesteal passive of Guy affects all 3 Teams.
