Blowgun

Blowguns are more tools of irritation than real weapons. Although they can be loaded with either sleep or poison darts, their effects can be easily shrugged off, and the dart itself will hardly injure an enemy. This means that the blowgun is fairly useless, except on the weakest of enemies.

According to Vetron's Guide to Weapons and Armour, the blowgun has a "1" effectiveness rating, and can be loaded with sleep or poison darts.

History
The blowgun first appeared in Savage Empire, as a weapon outside the "hierarchy" of weapons among the tribes of Eodon; it was most commonly used by Urali thugs. It appears again in the time of Ultima VII, used mostly by scoundrels, and can't be bought. In Ultima VII Part Two, the Goblin females of Serpent Isle are very fond of using this weapon with an annoyingly effective poison.
