At TwitchCon, I promised @KaidaWrath I would post an update on the “Legendary Hunter of the Shrouded Ghost” Commendation. We will soon be reducing this so that each grade requires defeating one Shrouded Ghost. Happy hunting, I promise it’s out there folks!
I am one of the lucky ones to have actually killed the Shrouded Ghost so my question is, does this mean I will need to kill the Ghost again to get this commendation or will killing any flavour of the Megs again trigger it?
