# Sling Bullet of Slaying
Rarity: Very Rare
A sling bullet of slaying is a magic weapon meant to slay a particular kind of creature. Some are more focused than others; for example, there are both bullets of dragon slaying and bullets of blue dragon slaying. If a creature belonging to the type, race, or group associated with a bullet of slaying takes damage from the bullet the creature must make a DC 17 Constitution saving throw, taking an extra 6d10 piercing damage on a failed save, or half as much extra damage on a successful one.
Once a bullet of slaying deals its extra damage to a creature, it becomes a nonmagical sling bullet.
