In-game description
"Ripper +2 This composite longbow was one of many made by a half-elven craftsman whose name has been lost to history. At one time there were several hundred in use, a favorite of scouts who patrolled the Anauroch desert, but many have been lost or destroyed. Only a few are still known to exist, and they see little use due to the tremendous strength they require." .
