Superior Defender

Superior Defender is a perk added to Fallout 3 in the Point Lookout add-on.

It provides a bonus of 5 to damage and 10 to armor while standing still. This perk is extremely useful to a Sneak based character, most of whom will have a tendency to sit still lining up shots.

Because the +5 damage is applied for each shot, it may show exponential increases in weapons such as assault rifles and smg's. At 100 Small Guns, the Xuanlong Assault Rifle's damage jumped up by about 30 when fully repaired, to 91. It is most likely a bug, unintended by the developers.

Obtaining
The Superior Defender perk is earned upon completion of The Local Flavor quest.

Trivia
The icon of the perk is likely a reference to Hellenic foot soldiers or a Spartan soldier as they appeared in 300.
