Sling

Slings are simple ranged weapons, consisting of a cradle for a projectile situated betwixt two pieces of cord. They appear in  Ultima III,  IV,  V,  VI,  VII, and  VII Part Two, as well as in the  Ultima Underworld,  Ultima Underworld II and  Martian Dreams.

Description
Slings first came into use during the time of Exodus, where they afforded a means of engaging combatants from a distance for those unable to afford or properly wield a bow or  crossbow. As they required but simple stones as ammunition, many Ultima games featuring slings did not require the player to collect projectiles in order to operate such weapons.

In  Ultima VII, slings are listed as having an effectiveness rating of 2. In  Ultima VII Part Two, they have a damage of 3 and a reach of 8.

Magic Slings
On Serpent Isle, a number of "magic" slings could be found scattered throughout the realm - although it is not known how their enchantments cause them to differ from mundane slings.
