The bow has a range of 75 feet, which is standard for shortbows. This item appears in Baldur's Gate II: Shadows of Amn and Baldur's Gate II: Enhanced Edition. This bow can be bought in Trademeet from an unnamed merchant after solving the genie problems.
|“|| Tansheron's Shortbow +3
The thin, frayed string of this bow appears unusable, but when it is drawn a solid but invisible arrow becomes tangible. The lich Tansheron gave this bow to his Watcher, the guardian of his keep who stood atop a tower with neither entrance nor exit. When anyone approached, down would fall a never-ending rain of phantom arrows until they were dead or fled. How this bow was wrested from the Watcher's hand is not known, but would probably make a great tavern story.
Note: avoid equipping normal arrows on your character, else the bow will fire these instead of the phantom arrows.'
