In-game description
"Magical slings are the hallmark of stout halfling warriors. Usually their mothers or a talented aunt will create this sling for the halfling lad or lass who is about to embark on their second great adventure. The reason that the sling is given on the second adventure and not the first is that many halflings decide not to pursue the life of an adventurer after getting a taste of it."
