Played first match of Neeko

Awesome, love it.

But i have one question concerning her W, and it's interaction with Sion that i didn't get a chance to test.

Would her W "stop" a Sion ult when he collides with it? I mean it's a clone, hes unstoppable yes, i get that, but if he runs into the clone it should collide right? Or does he just go through it?

Love the champ btw, super fun to play so far.
