The Sling of Unerring Accuracy is a sling weapon added in Baldur's Gate: Enhanced Edition.
This weapon adds a +2 bonus to attack rolls. It has the same speed factor as a regular sling. It can be found in a locked chest on the second floor of the Splurging Sturgeon and can be purchased from Black Lily in the Thieves' Guild in Baldur's Gate East.
|“||Dandifox was one of the greatest heroes of the hin, the small people also known as halfings. From the concealment of forest arbors he would attack rich caravans for a "tithe" which he then distributed among the local poor. The heroic robber finally met his end on the point of a guardsman's spear, but not before the constabulary had learned to fear and hate his infallible aim.||”|
