My buddy owns the PS4/5 version of D2R. I have it on my Steam account. Can he use his Battle.net credentials to log into his account to play D2R on my PC? He is also on my Steam family plan. I can't seem to find a way for him to do this. From what I understand if I disconnect my battle.net account from my Steam version I can't add his for 365 days. Is there something I'm not doing right? Does he really need to buy his own PC license to play on PC as well?
