Bonehead

 is a Fallout Tactics and J.E. Sawyer's Fallout Role-Playing Game Perk.

Fallout Tactics
With this Perk, the chance of getting knocked unconscious is reduced by 50%.

J.E. Sawyer's Fallout Role-Playing Game
You've been banged around enough that you've developed a very thick skull. Critical hits against your head have to exceed 25% of your total hit points to achieve a maim, and over 75% to achieve a break. BONUS: When combined with Unbreakable, this changes to 50% for a head maim, with no chance of a head break.
