Defoliator (Flask)

When you take the Attack action, you can replace one of your attacks with throwing a flask of Defoliator. Target one creature or object you can see within 20 feet of yourself. All Plant creatures within 10 feet of the point must succeed on a Constitution saving throw (DC 8 plus your Dexterity modifier and Proficiency Bonus) or take 2d4 Poison damage. Medium or smaller natural plants in the area wither and die, and wooden objects and structures take double the damage.
