Reverberating Stone

Activate ◇ (concentrate)

Trigger You use the affixed shield to Shield Block a melee attack

Requirements You're a master in Athletics, and you have the affixed shield raised.

This heavy metal emblem is mounted on the face of the affixed shield and has a dull gray gemstone embedded at its center. When you Activate the talisman, the gem shatters, releasing a powerful shockwave in a 15-foot area that must include the enemy who struck the triggering blow, if possible. Each creature in the cone takes 2d6 sonic with a DC 28 fortitude. Any creature that fails its save is pushed 5 feet away from you (or 10 feet on a critical failure).
