Anybody know which armor pieces go into looking like this and where I can find them.
There’s a tab in that article called Outfit that will give you answers. If you want the chest in plate, https://www.wowhead.com/item=26030/jesseras-fungus-lined-hauberk is from Bloodmyst Isle questing.
https://www.wowhead.com/item=25556/oversized-ogre-hauberk is the mail chest that’s available by questing. (The one they had listed is not available.)
