The Barrows is a haunted dungeon where the spirits of six legendary warriors wander, preying upon people who venture through their domain in search of their rare and valuable sets of armour. You will need to have finished the Priest in Peril quest in order to be able to get to the Barrows. The tricky part about the dungeon itself is the fact that your mini-map does not work, therefore making navigation extremely difficult. Not only that, but when you attempt to enter the room of the chests, you will need to solve a puzzle on the door that leads to the room. These doors are marked in blue.
