Shadow Heart

Trigger A creature approaches within 10 feet of the heart --- Effect The heart gives a slow beat, and all creatures in the room must succeed at a DC 30 will save or be Stunned 1 and unable to take reactions for 1 round (Stunned 3 on a critical failure). The dark heart then rolls initiative.

A swirling vortex of shadows forms around the heart, lifting all creatures in the room and slamming them forcefully to the ground, dealing 4d10 bludgeoning damage. Each creature must attempt a DC 30 fortitude save. Anyone adjacent to a wall may Grab an Edge with a successful DC 28 reflex save; on a success at Grabbing an Edge, the creature uses a result one step better than the roll of their Fortitude save. --- Critical Success The creature is unaffected. Success The creature takes half damage and is knocked Prone. Failure The creature takes full damage, is knocked prone, and is Clumsy 1 for 1 round. Critical Failure The creature takes full damage, is knocked prone, and is Clumsy 3 for 1 round.
