Splitting the sky is a feat done by wills clashing??? It’s not AP??? Wtf are you guys saying. Almost no attack had any effect at all on kaido except ACoC. That proves that the AP is just that huge. Ulti took hits from napoleon,Hera one Prometheus. Took thunder bagua from Yamato. But one hit from big mom with ACoC knocked her out permanently. This proves the difference in AP. Zoro is nowhere near Luffy right now in AP
splitting the sky can only be done by 2 people clashing with advCOC not with strong punches and kicks
COC is an ability to overpower the will, so attacks from advCOC contain the users strong will within them, that's why unless you yourself can protect from the attack with advCOC you will get damaged and knocked out more often than not, it doesn't mean those attacks are strong!
strongest AP attacks cause tons of AOE damage, Luffy with KKG can probably destroy a city but base Luffy with his no name advCOC attacks wont even cause close to the same level of damage.
