how come that Hiruzen's buff doesn't stack with Warrior's Killing Intent if this skill is not a jutsu enhancement

Lightning Style Enhancement - Increases Ninjutsu and Attack by 40% up to 3 Lightning attribute units from your Lineup, lasts for 5 rounds.(this is the passive that is not stack-able)

I didn't mention that Mifune's buff can stack in Tobirama i included their that Tobirama is not a sword type user that's why i didn't added up his buff!

and also i just didn't included Guy or Asuma buffs to others because guy and asuma buffs is for group only + i included Guy's buff the lifesteal because konan can still lifesteal cause her standard is taijutsu :)
