Everyone in Fallout tells you that Deathclaws are bad news. Everyone tells you it would be suicide to take them on alone. But this is a game, I'm the hero and I win against impossible odds all the time.
Well, it seems they really mean what they say this time. Deathclaws are extremely dangerous. They are fast, can take an absurd amount of damage, have a very high damage threshold and they kill you in a few swings.
So a typical encounter starts like this
and ends like this
In Fallout 3 you could just shoot them with the dartgun and they hobbled along while you walked backwards emptying your gun into their face.
What are effective tactics for killing Deathclaws in Fallout New Vegas? I'm not really looking for exploiting glitches like bad pathfinding, but legitimate tactics to have a good chance against those beasts.
