Agility

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

Fallout, Fallout 2 and Fallout Tactics
Action point allocation is based on the AG stat. Therefore, a character that wishes to keep an enemy on its toes, or claws, needs to have a high Agility in order to have multiple combat moves. Additionally it allows the character to dodge better. It is a critical stat for anyone interested in the more mobile and visceral skills, such as unarmed and small guns. Other skills rely on it, but these have higher values in AG investment. In Fallout Tactics, the Continuous Turn-Based (CTB) style required real-time generation of action points that was based on the character's AG stat.

Ways to increase Agility

 * In Fallout 1, the Brotherhood of Steel in Lost Hills can perform an operation to permanently increase Agility by 1, assuming the player can afford it.
 * In Fallout 1 and Fallout 2, Agility can be raised by using psycho which gives a temporary +3, and by using Buffout which gives a temporary +2.
 * Agility can be raised in Fallout 2 by using Monument chunk which gives a temporary +3.
 * In Fallout 2, taking the Gain Agility perk also raises Agility by 1.
 * In Fallout 2, The Chosen One can get a permanent +1 Agility by first sleeping with Miss Kitty and immediately afterwards sleeping with one of her prostitutes. (Restoration Project only)

Fallout 3
Modifies: Action Points available for V.A.T.S., and the Small 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*2, and can be raised by perks and some items).

Fallout: New Vegas
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
