You summon a spectral herd of ponies to drag off a creature that you can see within range. The target must be Large or smaller. If it gets a failure on a Dexterity saving throw, a spectral rope wraps around the target, which falls prone and is restrained.   It is immediately pulled 60 feet behind the galloping herd, in a direction of your choosing. The target also takes 3d6 bludgeoning damage from being dragged across the ground. While the target is restrained in this way, it is dragged another 60 feet and takes another 3d6 bludgeoning damage at the start of each of your turns. The ponies continue running in the chosen direction for the duration of the spell. Once the direction is chosen, you can’t change it, but the ponies do swerve around impassable obstacles. They ignore difficult terrain and are immune to damage. The restrained creature can escape by using its action to make a successful Strength or Dexterity check against your spell DC. The spectral rope can’t be severed.
