Basic Pest (D)

You have a swarm of mites, fleas and other parasites that immediately appear on every creature you can see. The target must succeed on a Constitution saving throw or take 1d6 poison damage and move 5 feet at random (if it can move and has a speed of at least 5 feet). Move d4 direction: 1, up; 2, down; 3, right; or 4, left. This move does not provoke attacks of opportunity, and the target does not move if the turning direction is blocked.

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