Voli can flip through morg spell shield

It works vs enhanced magic autos. But her spell damage shield only stops spell damage and effects related to those. Now if it worked instead like a banshees veil shield were it just eats the next skill that targeted her that'd be different. There are other skills that bypass her shield. Pretty sure Garens enhanced auto with silence also bypasses her shield.

So short answer if voli did magic it would prevent it but he does physical so it doesn't.
