god damn it deathclaws are pretty damn tough even at level 30

aka i got owned by an alpha male deathclaw.

i can't wait to fight the legendary one.

Me, Boone, and ED-E already wiped that S.O.B. off the face of the earth. Got a unique grenade machine gun called Mercy out of the deal.  Boone was armored in salvaged NCR Power Armor and was wielding a mini-gun, ED-E had the Followers of the Apocalypse weapons upgrade, and I was wearing Brotherhood of Steel Power Armor and was armed and extremely dangerous with a missle launcher.

Also eliminated two other legendary creatures beforehand.  First was the Legendary Cazador in Silver Peak Mine.  Killed with Sniper Rifle.  The other was the Legendary Nightstalker in Bloodbourne Cave.  Killed with Knock Knock, a unique fire ax found in Camp Searchlight Firehouse.
