With Noblegarden starting today we finally learned how to obtain the new mount added with the event, the Noble Flying Carpet.
The mount is a rare drop from the cache of the event Loot-Filled Basket. While we have limited data, it seems like the mount is a 1% droprate from the cache.
Loot-Filled Basket is obtained from the daily quest Feathered Fiend. The daily quest starts from Noblegarden Trinket, which can be obtained by killing Daetan Swiftplume, a new special summoned elite from Noblegarden. You can summon Daetan Swiftplume as part of the Noblegarden questline. You do so by dragging the golden egg to its nest.
Note that you don't need to do the questline to loot Noblegarden Trinket and obtain Loot-Filled Basket; all you need to do is help kill Daetan Swiftplume.
Once you obtain the Noblegarden Trinket, you can turn it in at Razor Hill to Sylnaria Fareflame or at Goldshire to Zinnia Brooks.
The following items can be inside your Loot-Filled Basket. You can loot Loot-Filled Basket once a day per character. Unlike past Dragonflight Holiday additions, you don't have a higher chance to receive rare items on your first character of the day.
