Recoil

A [Firearm] with [Recoil] is more difficult to shoot multiple times on the same turn. When you use a weapon with [Recoil], every [Attack] you make with that weapon beyond the first on the same turn has its Difficulty Level raised by one. This DL increase is cumulative. [Recoil] is a [Weapon Type] characteristic and is found on [Heavy Pistol], [Rifle], [Shotgun], and [SMG].

For example, the Desert Viper is a Heavy Pistol, which means it has the [Recoil] trait. The first shot with the Desert Viper using the Single Shot trick has a DL of Moderate (14). The second shot (with Single Shot) on the same turn has a DL of Hard (20), and the third shot has a DL of Severe (26).
