Cold Blooded. How it works? Does it stacks from clones,sharks/e.t.c? Or nah? Why I ask is, Edo deidara has same discription text, as it goes - Increases Crit when a unit is defeated - , same as Cold blooded, where its Increases Atk/Nin when a unit is defeated. Why i raise interested here is, deidara has a text pop up when clone dies, Crit increase, while Orochimaru dont get the atk/nin increase text. So is it just typo and it works only when ninjas are defeated or does it still works on smaller units?

I ask this, cuz if it works, * can get *y with orochi/deidara/kisame team if you know what i mea, hehe.
