As we all know the shield broke in Fear Itself, but it was broken by a skyfather which we know a lot of skyfathers have powerful magics that can manipulate things at a molecular level.
Yes, I understand why the shield had to break to show how much of a threat the Serpent was. But seriously?
Come on man. We don't need the damn thing breaking every time there's a planet level threat coming along. Especially after it was suppose to be stronger due to being brazed (brazing adds strength to material, welding does not) by dwarves and magically enchanted.
