Battleplate of the Highlord
Plate set. Warlords of Draenor. Doesn't allow bottom half of a tabard through :(
Battleplate of the Highlord is a transmog reward obtained from the Cache of Nightborne Treasures, which is earned through weekly quest events and Mythic+ activities.
Complete weekly event quest
Complete the weekly event quest "Emissary of War" marked with Heroic difficulty to receive a 
Cache of Nightborne Treasures. The cache guarantees a minimum item level of 885.
Open cache for transmog
Open the Cache of Nightborne Treasures to reveal the Battleplate of the Highlord transmog piece.
Tips
The quality of the cache is determined when you obtain the mission, not when you complete or open it; Mythic difficulty missions reward higher-quality caches than Heroic or Normal.
