Meta description:

This small, jagged piece of black granite is etched with glowing runes that seem to pulse with an energy. The stone is rough and textured, with a weight and density that belies its size. When thrown, the stone explodes in a burst of sound, causing a loud, disorienting blast that can disrupt an enemy's focus and resilience. The character throws the stone, which causes all creatures within 2m of the impact to succeed a Vigor test or suffer a -2 malus on their Resilience for 12 seconds.
