Built to Destroy

 is a Trait which only appears in Fallout: New Vegas.

Though it says that "The flamer that burns..." it is not directly referring to the flamer weapon; instead it is substituting "flamer" for "candle" in the proverb: "The candle that burns twice as bright burns half as long." By choosing this trait, you are increasing the chances for your weapon to do critical damage in combat as well as increasing the rate at which it will eventually break.
