To new players, or for those who haven't stopped by in a while, getting to level 50 in Fallout 76 may seem a bit daunting. But as you need to get to said level if you want to turn your character into a ghoul, it's a hurdle that you'll have to overcome.
Now, if you already have a character over level 50, there's nothing stopping you from converting that to a ghoul. But if you're like me and don't want to sacrifice your long-term character, even if you can reverse the process, then creating a new character is your best bet.
