You conjure a small toxic cloud of billowing poison centered on a creature within range that you can see. The creature must succeed on a Constitution save or take 1d4 poison damage and have disadvantage on the next attack roll it makes before the end of its next turn. Creatures immune to the poisoned condition are unaffected.
This spell's damage increases by 1d4 when you reach 5th level (2d4), 11th level (3d4), and 17th level (4d4).
