In the Horde's Grip

When your skeletons and zombies attack, their skeletal claws and rotting hands clutch and tear flesh. Weaker foes are caught in their grip. You command your horde to perform a Mobbing Assault. Instead of being Off-Guard, a creature who takes physical damage from failing the saving throw is Grabbed by your horde (Restrained on a critical failure). The DC to Escape from your horde is equal to your spell DC. Creatures grabbed by your horde that fail a saving throw against the horde's Mobbing Assault take 2d6 persistent bleed damage.
