Yeah, I should have not used durability. I used it referring to Meliodas and Diane then put all of them together, what I wanted to say is that, the Sins Meliodas, Diane, Ban and Gowther can take deadly hits much more easily than King, who has no healing powers or a body making him particularly durable compared to the others, Merlin has very powerful barriers, and Teleportation. He is the most vulnerable of the Sins so far against opponents of his level, Helbram only managed to hit him with slaps because he was not serious at this time, the four I cited would be even less affected by that. Gowther was pierced by break and the hole was still visible when Dreyfus awakened.Durability is a murky issue all around. Meliodas has his demon based regenerative abilities. Ban is effectively immortal and has infinite stamina. Diane is a giant that can seemingly survive being pierced, in this regard she did better than meliodas when gilthunder attacked him. Gowther's body is not real... Given fraudrin's intervention we can't even tell to what extent being stabbed affected him. King is supposedly weak but he took helbram's slash rather well and survived being thrown around by helbram. Merlin is supposedly physically weak. We know nothin of escanor. With that in mind, ban is not particularly durable either. If he takes damage he will simply regenerate. Its not like he can take the damage or go otherwise unaffected by it. I guess it depends on what exactly you consider durability...
