Patch 10.1, Embers of Neltharion, is adding a new outdoor zone, the Zaralek Caverns. In this underground zone, players will be able to obtain new pieces of gear, and they do not look too shabby! These are Black Dragonflight inspired. Lead Quest Designer Maria Hamilton mentioned during the Patch 10.1 Reveal Video that these are inspired by Blackwing Lair as well:
Our outdoor sets for weapons, armor and even mounts are themed to the Black Dragonflight.
