Illoai 's E

I was playing against an and I don't know if its me but I swear the tentacle that hit me didn't show the area it was striking and it wasn't when she was ulting either it was just off the debuff her e applies. I was running and the other ones show up and show the attack area but the one that hit me just popped up and then smacked with no warning.

Is that normal for it to just show up and then hit instantly. I thought there was the wind up and the area that it was gonna hit.

She was using the void skin.
