Exterterminate

You bring death upon Tiny non-magical Beasts. You fire a green mist at a point you can see within 30 ft that instantly kills pests. It does not affect creatures that have been polymorphed or were the subject of a spell that changes a creature’s size. It is effective on common vermin such as a mouse, a rat, a beetle, or a fly. If the target was sufficiently small, such as tiny ants or fleas, a volume of up to 0.5 cubic feet could be made free of the pest.
