At Rank 3 and Rank 5 in Iron Banner, players will have the opportunity to purchase Etheric Light from Lord Shits-on-Lawns. No one knows if you can only purchase one from him at those ranks, or if you can purchase many; but you will be able to purchase it from him in the Iron Banner. Further proof that Bungie is making it far easier for PvP-centric players to hit end-game content than they are for PvE-centric players...
