I was doing crota's end with a friend to get his new character up. I tried to use my ward of dawn, but it wasn't working. I thought that it was just glitching, so I left the game, and a couple days later, I got back on. I thought my super would work, but I did king's fall and crucible, and it still wasn't working. I need to know how to fix it, and how to make sure it doesn't happen again. Please help
