In the latest addition to the series of pet battle dungeons, we are revisiting the old home town of the Gnomes: Gnomeregan!

To start your journey through this dungeon, head over to Tanzil if you're Horde or Dana Pull for Alliance players. The breadcrumb leads you directly to the instance entrance of Gnomeregan, where you will meet Micro Zoox who will offer you the instance quests, start the queue for it and also sell you pets related to the Gnomeregan dungeon!

Your first playthrough grants an Ultimate Battle-Training Stone, and following runs in the Challenge Mode (no healing) give the new currency Pristine Gizmo which is used to buy pets from Micro Zoox.
