Idk why people use the SFX “zzt “ or “.zat” to say if it’s Advanced CoC when it’s has been used on non advanced CoC user and Non CoC user like Kidd and law.
black lighting also isn’t enough because characters like jimbei also it’s used black lighting like CoC user
SFX + black lighting isn’t even enough because ulti also have used it against luffy
i don’t see gaban having CoC let alone advance CoC but we must admit oda failed to separate CoA and CoC because we don’t know who is using CoC or not.
the only way to know if it knocks out the people around you or the is massive black trail like the elders
