Venomous Sting

You brandish the weapon used in the spell’s casting and make a ranged attack with it against one creature. On a hit, the target suffers the weapon attack’s normal effects and takes an extra 1d8 poison damage. If the target currently suffers from the poisoned condition, the target instead takes 2d8 poison damage.

At Higher Levels. At 5th level, the extra poison damage increases to 2d8, and the damage the target takes if poisoned increases to 3d8. Both damage rolls increase by 1d8 at 11th level (3d8 and 4d8) and again at 17th level (4d8 and 5d8).
