Haunted Inn is a small dungeon that can be found within Westmarch Heights in Act V of Diablo III. It is the site of The Haunted Inn event. The dungeon and event always appear together or not at all.
The inn is a small two-floor building along the main roads of the Heights. Upon entering, the doors lock themselves shut, although Town Portal still works. Two conspicuous piles of debris sit near the back of the large main room. A blue skeletal spirit is visible on the stairs but retreats up them when approached. From the top of the stairs, it is visible at the back of an upper floor dining room, waiting next to a Resplendent Chest. Entering the room reveals it to be a Summoned Soldier, and several Revenant Soldiers and Archerss join the ambush.
The chest can be looted after defeating them, but returning down the stairs causes more Soldiers, Archers, and Vicious Hounds to burst out of the debris and rise from the floor itself. After the second ambush is handled, Nikkorax, Converted Innkeeper, a unique Summoner of the Dead must be slain to end the event.
