YouTuber "TheVMPshow" made a series on m&b a world of ice and fire 2.2, during the series, he had a video where he'd taken prisoner a Lannister Lord and gave him the option to take the black and go to the Nights Watch, when he'd done this he'd obtained all of that lords unique Lannister Lord amour and all his gear. I'm wondering if there are certain conditions that need to be met to do this on 4.2 or know at least whether they've removed it as a whole since 2.2?
You have to own King's Landing, making you the king or queen of the Seven Kingdoms.
