I know not everyone wants to be told the locations of the legendary items, but for those who are having trouble here is a list of the legendary items and their locations. I've seperated this from my other guide as it contains major spoilers.
I am listing everything by chapters, added separate headings to each chapter and item, so you don't have to view all the items at once if there is a particular item you wish to read about. The name of the quest is given if the location contains multiple quests.
Again you are about to read spoilers which will reveal the locations of the legendary items
