Dead Wind Cavern

 is a place in the Mojave Wasteland. It is an abandoned cave. 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. Using an Anti-materiel rifle with armor piercing rounds is an easy way to kill deathclaws as well as the Alien Blaster or the YCS/186 Gauss rifle. The Gobi Campaign scout rifle is also a great choice as it has a 5x critical strike multiplier and only uses 33 AP per shot with a 2.5 shots per second fire rate.

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