Bone Yard

The ground in a 20-foot radius centered on a point within range writhes and churns as the arms of zombies and skeletons burst from the ground, grasping and swatting angrily. The area becomes difficult terrain for the duration. When a creature moves into or within the area, it takes 2d4 bludgeoning damage for every 5 feet it travels.

When you cast the spell you can command the undead arms to allow specific creatures to pass unhindered. Creatures designated in this way may move through the area as though it was normal terrain and receive no damage. 

You are able to move through the affected area unhindered.
