I strongly empathize the "the" in this line, meaning there is only ONE weapon described as the "true" weapon of light, of course. I have had word that many people, though very few, may already have this weapon. I dare say it is the Vex Mythoclast. I personally think this is genius of Bungie to do, nurfing the VM until it is of true value in the dlc. But hey, I'm not here to ramble, I'm here to offer my services. I just so happen to be a lvl 30 warlock WITH a fully upgraded VM. Add me. Don't add me. It's o.k, I'll be fine, I promise you. PSN: charlie_boy_410
