Destiny, Bungie's follow up to their iconic Halo Series, is all about that post-game grind. Players must improve their reputations through different activities and collect marks to turn in for better gear. However, these items can be improved through different equipment upgrades. Equipment upgrades are made from collecting upgrade materials. Upgrade materials are primarily obtained through exploring the PvE environments in the game. At early levels, you won't need many upgrade materials so some players choose to skip them when they see them. However, you should never pass up a chance to pick them up as at higher levels, you will need a ton. Some can occasionally be easy to miss, especially if you have never seen them before. So for those looking to do some upgrade material farming, here's the necessary materials and where to find them.
