Agility/Fallout: New Vegas

Agility is one of the seven primary statistics in the SPECIAL system.

Modifies
Action Points available for V.A.T.S., draw and holster speed, reload speed, and the Guns and Sneak skills.

Agility determines the number of action points available for use in V.A.T.S. (base AP determined by 65 + (Agility x3), and can be raised by perks and some items).

The holster/reload time is modified in percentage by 10*(1+Agility)% from 100% base value. Agility below 5 makes reloading slower.

$$reload\,time\,in\,seconds = \frac{WeaponReloadTime}{((0.5+Agility*0.1)*modifier)}$$

Modifier Rapid Reload = 1.25
