 is a perk added to Fallout 3 with the Broken Steel DLC.

It increases the regeneration rate of Action Points.

It has been reported that the perk is non-functional on both the PC and Xbox 360 with the version 1.5 patch issued with Broken Steel. While the perk does function, the rate of regeneration of action points is extremely low (1 AP per 10 seconds).
