EDIT: bumped for 2015 Iron Banner EDIT:Friday December 12th. I saw my man Xur is selling upgrades for the weapons. It costs a TON of glimmer if you want them all upgraded. I am guessing each week he will show different weapons and armor to upgrade. I just do not want some of you fav weapons left behind! This video is about getting glimmer back for the Iron Banner. Same rules apply for Xur upgrades. You need glimmer! It has been used as a long time. I am very surprised it has not been patched yet! A lot know about it and some do not. This is for those people. Good luck!
