Recently Erich Schaefer compiled data on loot drops for a test character, and made this amazing infographic. This was sent internally for us to see how a specific character may encounter possible drops. Keep in mind that another character's loot drops will be affected differently depending on elements like play style, quests, and character.
It's rare to get such an elaborate and clearly defined loot breakdown, and we wanted to share it with you. As we continue to balance all aspects of the game, statistics like these will change. This isn't final data, but it's a great peek at just how much there is to find. Thank you Adam for the experiment, and Erich for creating this on your weekend.
