2 interesting bugs with Sylas

Sooooo, You know that item riot said they were going make available for Kalista (The Black Spear) to buy in the store so she can switch on oathsworn about a year ago but it never happened? Well when you play Sylas you are able to buy this item for 0 gold and use it on Allies but good thing it dosn't do anything but you are able to buy it as many times you want after you use it.

Bug Numba 2: when you steal a champs ult with yours you Apparently steal their voice too and voice lines too. For example my last game i stole Ezreals ult and used it on him, after he died i fat fingered and did the taunt #2 by mistake and heard him yawn and say " call me when the stakes are higher" i instaly checked and found out all his voice lines and in game voice lines are now Ezreal's. I don't know about you but if this is a bug or not but lets say its a feature.
