Is Advanced Haoshoku the only way to split the sky?

[SSJ2]

And if not, is it proof that current Luffy > Admirals?

 

[Future Warrior]

Doesn't look like Advanced Haoshoku to me.

 

[SSJ2]

Maybe not. It could be that Oda didn't want to reveal it though in the second case. When Kaido used it for the first time we didn't see the black lightning coming from his weapon prior to the attack, only after. The same could be seen after Big Mom and Kaido clashed.

 

[Future Warrior]

I think he can use Thunder Bagua without CoC.

 

[SSJ2]

In which instance?

 

[Future Warrior]

When he 1-shot Luffy.

 

[SSJ2]

I thought Luffy said he used it in that instance.

 

[Future Warrior]

I assumed he meant when he did this

 

[SSJ2]

Yea, that would make sense.
