Exploding Skeleton (CR 1/3)
An exploding skeleton detonates in a burst of razor-sharp bone fragments when it dies. Anyone within 10 feet of the skeleton when it is destroyed takes 1d6 points of damage. A DC 10 Reflex save halves this damage.
Skeletons are the animated bones of the dead, brought to unlife through foul magic. While most skeletons are mindless automatons, they still possess an evil cunning imparted to them by their animating force—a cunning that allows them to wield weapons and wear armor.
