Skiprock

Skiprocks were specially made, polished stone projectiles invented by halfling weaponsmiths and prized by members of that race.

Weaponology
Skiprocks were finely weighted and shaped to ensure they were perfect for throwing. If thrown well enough, after hitting a target they would typically ricochet and hit another.

Besides their use as pure projectiles, skiprocks were known to be used as bullets for slings or the heavy warsling. However, when shot from a sling they typically did not ricochet.

Notable Users of Slingrocks
Skiprocks were primarily wielded by halflings, especially lightfoots. They were also a standard weapon in the arsenal of any warsling sniper.
