— In-game description, Fallout: New Vegas

Hot Blooded is a trait in the Fallout: New Vegas add-on Old World Blues.


When your health drops below 50% you deal +15% more damage (see Bugs below), but you also suffer -2 to Perception and Agility.


  • The negative effects of this trait can be offset through the use of chems, armor, clothing, other perks or other traits. Sustaining the effect by remaining at the required health level or below allows it to combine exceptionally well with Ferocious Loyalty and high companion nerve.


  • Although the trait description claims the bonus is 10%, it is actually 15%, making this trait even more useful.
