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 weapon itself know as The Flamer. Basically by obtaining this perk 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. If you don't mind constantly repairing your weapons, this perk is somewhat decent, but not recommended for hardcore mode.
