4Th Weapon->Start a level on Chaos mode or start a level 3 stars above on hard mode
Hints:Do the Samurai level 1 on Chaos mode it's easy there
My team:Orochi lvl 99,Sun Wukong lvl 99,Started with Lubu lvl 45 then Tadakatsu Honda 49
3rd Costume->Increase character proficiency to 10
Matzukaze/Red Hare->Raise Cavalry to 10 with Lubu or Keiji Maeda
Dodomeki(The evil ninja)->Collect about 5 to 10 gems
1000 KO-> The easiest way to get 1000 Ko is the 2nd last level of Orochi quest just distract Nobunaga then kill the soldier but get away from nobunaga i did it pretty quickly!
