Dead Wind Cavern

 is a location in the Mojave Wasteland. It is an abandoned cave near Primm Pass and slightly south of Harper's Shack (which itself is south of the REPCONN Test Site). The Brotherhood of Steel raided the place but the mission was unsuccessful. The Mercy gun is in here. It is home to a wide variety of Deathclaws, including the most powerful enemy in the Mojave wasteland, the Legendary deathclaw.

Layout
The entrance of the cave rests at the end of a long, shallow valley running north east to south west, inclining towards the cave. A small pack of Deathclaws and Young Deathclaws congregates near the entrance, and there are good sniper positions along higher ground to the north west, and lower ground to the north and north east. Approaching from the west, along the mountains also provides a good position to attack this pack from atop a large rock the Deathclaws cannot climb.

Once inside, there should be one or two Deathclaws patrolling the area near the entrance. This initial "room" funnels into a single passage which quickly forks left and right. The right fork leads to a long, rectangular hallway/room and contains two or three deathclaws before it dead-ends. Looking left at the end of this room reveals an impassible formation of rocks and columns which you will not be able to shoot through (despite looking like you should be able to).

The left fork also opens into a long, rectangular area with another two or three deathclaws. A passageway to the left leads to a hatchery area, containing a Mother Deathclaw and a few Baby Deathclaws. The Deathclaw mother usually has 3 Deathclaw eggs, worth 400 caps each, on her body. Just past this passageway, after being forced to turn right, is the impassable rubble between this area and the "right fork" from the first split. There's a skeleton and a duffle bag lying up against this rubble, accessible from this side.

The final room of the cavern lies to the left, just before the duffle bag. It should contain two normal Deathclaws and a Legendary deathclaw. This is also the location of a dead Brotherhood of Steel Paladin wearing Brotherhood T-45d Power Armor and a T-45d Power Helmet, with a few dozen 40mm grenades on her body (both normal and incendiary varieties). Mercy, a unique Grenade machinegun should be lying beside the body.

Notable Loot

 * Mercy in the room with the Legendary deathclaw.
 * There is a dead Brotherhood of Steel Paladin with some 40mm Grenades, Brotherhood T-45d Power Armor and T-45d Power Helmet in the room with the Legendary deathclaw.
