(I'm going to go out on a limb and guess that'd count as a Dark attack, which Zain has an expressed vulnerability to. That said, attacks specifically like that have failed to kill him in-canon before.)

I don't know if it was established that Zain's weapon can rust or not, but assuming it can (and that Yanald can overcome the straight-up power contained within it by proxy of Zain wielding it), the Tiphareth would repair it over time I'd imagine. There's also Babel, which is, y'know, made of wood, and thus doesn't rust. He'd probably respond with the Death Arcana, since that's how he beat Ruin, but eh.

So how do Soul Cores work again?
