Simple Ranged Weapons
A blowgun is a simple ranged weapon consisting of a narrow, long tube designed for firing light projectiles or darts. You attack with the by inserting a needle inside the pipe, then blowing sharply into one end to shoot the projectile out the opposite side. Unlike most ammunition weapons, a blowgun can be both loaded and fired using only one hand instead of two.
Special. The force with which you shoot a blowgun needle depends on your exhalation power and lung capacity. When you use ammunition to make a ranged weapon attack with this blowgun, you can add your Constitution modifier to the damage roll instead of your Dexterity modifier.
