I hit Sivir with Zenith Blade while both spell shield and Banshee's were active. Normally, if one is active I do no damage and don't snare but I do dash. With both, however, I popped both but didn't dash either.
Well with both up at the same time you're gonna proc both. Two birds with one stone. If she had just let banshee's handle it, she would still have a spellshield.
It has two spell components attacked to Zenith blade. The first is the root which procced one of the two spell shields and second is the dash which procced the second spell shield.
