Missile weapons fire projectiles toward an enemy target. Those projectiles are subject to a variety of calculations and randomness that can cause them to veer off the intended path. Among other things, learning some of the [[skills]] associated with missile weapons and improving one's [[Agility]] stat can improve the accuracy of missile weapons.
The first component to a missile weapon attack is determining the trajectory of any projectiles.

Each projectile fired is additionally affected by the wielder's aim variance. '''AimVariance''' begins with a standard {{dice tooltip|2d20}} dice roll shared by all missile weapons. The value can then be modified by attributes, skills, weapon mods, and other factors, and it can sometimes be reduced to 0.

Bow and rifle shots using [[Sure Fire]] or [[Beacon Fire]] always have an aim variance of 0.
In the following cases, aim variance is always set to 0.
* Bow and rifle shots using [[Sure Fire]] or [[Beacon Fire]].
* The final shot of a barrel from {{favilink|Ruin of House Isner}}.


Otherwise, the general formula for aim variance is as follows.<ref name="MissileWeaponFireEvent" />

When the projectile actually hits the target, regular damage calculations occur. However, there is a -5 DV penalty. If the target has [[Swift Reflexes]], the penalty will not be inflicted. If the creature is immobile, the DV is set to a flat -100.
 
Also, info on damage calculations is not found in the linked penetration article, as claimed. Rather than adding it there, it might be better to explain the damage calculation here for a ranged weapon & ammo, similar to the example in the [[Melee weapon combat#Damage Rolls|Melee weapon combat]] article.}}
