Among the many secrets in Dragonflight Patch 10.2, the Cowl of the Wolf Ancient is a special cosmetic wolf helmet available only to Orc characters, hidden inside the Emerald Dream!
The Cowl can be found immediately after finishing Call of the Dream and entering the Emerald Dream, hidden away inside a cave on the westernmost island, with no other requirements to obtaining it — simply fly over to the cave entrance at 33,81 on the map and loot the cowl from its stand next to the oddly lifelike Statue of the Great Wolf.
The Cowl is lootable from this little skull stand adjacent to the Great Wolf, though only Orc and Mag'har Orcs can use it.
Non-Orcs aren't completely left out though! While not required to obtain the helm, that statue holds a different secret which any player can obtain with a minor detour. Shortly down the path at 30,80 on the map, players may see a shiny Mark of Goldrinn sitting upon a boulder.
Interacting with it will trigger a 60 second Wolf Spirit Guardian buff during which an Honored Wolf Spirit will follow you. Bring the spirit to that Statue of the Great Wolf (aided by the convenient Treasure Chest icon on your minimap), and it will have a special dialogue option, revealing a nearby treasure chest containing the Claw of Lo'Gosh!
Unlike the Cowl, the Claw is usable by all characters that can equip fist weapons!
Back outside the cave, players may spot a similar Mark of Ursol outside, which activates a similar 60 second buff and accompanying bear spirit leading to another treasure, but we'll save that mystery for another time!
