Dragonwilds Mount Guides
Quick answer
The Magic Carpet comes from Moon Garou quests, but the mount system still requires The Wild Hunt in Fellhollow. Earning a skin first does not bypass that prerequisite.
Available guide
The Magic Carpet guide explains the two-part quest requirement and the launch-era interface confusion around greyed-out variants.
Future mount pages
Individual variation pages should only be indexed when the exact source, prerequisite and cosmetic distinction are verified. Repeating the same generic mount text across skins would not help players.
