Druids have a selection of four armor sets in the Dungeon category. All of these sets will have class restrictions and individual stat bonuses for each piece that the character is wearing plus set bonuses for having complete sets. These are ranked sets and are in stages. These are the stages that you can get the dungeon armor sets in, what they are comprised of, and the total stats for the set. The links will open into further indepth articles of each of the armor collections.
