Tick Attack

From your unwashed, matted fur a snapping plague of ticks and fleas spring forth, momentarily swarming a creature you can see within range. The target must succeed on a Constitution saving throw, or it takes 1d6 poison damage. They say the itching does not stop for days afterwards. 

The spell’s damage increases by 1d6 when you reach 5th level (2d6), 11th level (3d6), and 17th level (4d6).
