2-Plus I suspect when Yang goes all flamey she makes herself vulnerable 1-The sword? Most people that think Adam has such ability think it's his Semblance, not something done by the weapon. (You know, cause he himself glows).

2-Vulnerable as in "gets mad and drops her guard"?

In line with the actual topic....Adam's red blade is likely Dust, actually, in spite of what was argued here. Specifically Fire Dust. In the Black trailer some of his slashes have a flaming trail. There are even some pictures that prove it (though I don't know how they're called. Will look for them later if no one posts them here).
