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
A lot of twists and turns, it's easy to get lost. Several Deathclaws (2-4) are located within the first chamber (be careful, they can easily ambush and kill you). There is a Brotherhood of Steel paladin near the far end of the cave after you kill the Legendary Deathclaw inside. The Paladin holds Mercy, a unique Grenade Machinegun, as well as Brotherhood T-45d Power Armor and Helmet, and about 30 rounds of ammo. Several of the Deathclaw den mothers contain Deathclaw eggs that are worth 400 caps each.

There are several ways to defeat these deathclaws, you can use an Anti-materiel rifle with armor piercing rounds, the Alien Blaster, the YCS/186 Gauss rifle, the Gobi Campaign scout rifle (as it has a 5x critical strike multiplier and only uses 33 AP per shot with a 2.5 shots per second fire rate) a Riot Shotgun (with a heap of slug rounds and used in conjunction with the Shotgun Surgeon perk) and even This Machine, will help you provided of its high DPS. The easiest way is to equip a Sniper Rifle with the Silencer mod and just sneak through the cave taking out the Deathclaws from a distance.

There is a section near the entrance where you can climb and Deathclaws won't be able to hit you.
