Darius can't damage Yoricks cage when activating "W" . GAMEBREAKING BUG
If Darius activates his W-ability he cannot damage Yoricks cage anymore, which is a gamechanging bug and has to be fixed as soon as possible. I see that this bug is reported since over a year now so i beg riot to finally fix this.
You can see in the video that i do 3 w attacks after my first normal attack and the cage doesn't break down. (it disappears because the time ran out.) I did not hit a mist walker or yorick (he gets no bleeding damage). Also his cage is level 1. It has only 2 HP.
