Casting Time: 1 action
Range: Self (5-foot radius)
Duration: Concentration, up to 1 minute
A swarm of spectral rats, centipedes, spiders, ferrets, frogs, and other assorted vermin emerge from the earth beneath your feet. When a creature other than you enters the spell’s area for the first time on its turn or starts its turn there, the vermin claw and bite their way over it; it must make a Dexterity saving throw. On a failed save, the creature is restrained.
A restrained creature that begins his turn in the spell’s area must make a Constitution saving throw or take 6d4 damage, or half as much damage on a successful one and may make a Reflex saving throw. On a successful save, it is no longer restrained.
On each of your turns, you can use a bonus action to move the swarm 30 feet in any direction.
At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the damage is increased by 2d4 for each slot level above 2nd.
