it's confirmed it's constant CoC coating that makes her durable?
i remember saying it might have something to do with Haki, but i didn't know about CoC
It clearly is coc at this point, because we already saw her use armement on top of her skin while she was in a normal emotional state
But anyways you guys are being ridiculous for thinking that big mom was as durable as she normally is when she was mentally a child
She literally got her skin pierced through by queen's men , you guys seriously think big mom in that state where she can be so easily damaged is more durable than sanji?
