how i do that? i need to do for every killer?
You find the crown in a trail and interact with it. If sparkles appear at the side of your screen you have it.
Yes you must do this for every Non-licensed killer if you want them to have it.
í just need a kill for the skin?
No. Just get a Crown and dont DC.
I tried this when I was playing on PC and use Demogorgon, after the game it did said Crown unlock but when I look at my costumes I dont have the crown. But when I used a Wraith I got the crown, Is this a bug??
Demo is a licensed killer. Skin is for non licensed
