Just Lucky I'm Alive

Just Lucky I'm Alive is a perk in the Fallout: New Vegas add-on Lonesome Road.

Effects
You've had lots of close calls. Whenever you finish a fight with less than 25% health, your Luck increases by +4 for 3 minutes. You are also immune to critical hits, and your own critical hits inflict +50% damage. This perk requires you to have neutral karma.
