Herbicide Potion

Herbicide Potion (or simply Herbicide) is a poisonous potion that kills or damages plants. It has a disgusting taste and is not fit for human consumption since it may affect the drinker's health. The recipe for this potion can be found in Magical Drafts and Potions.

If you drink the potion, you take 3d6 poison damage and you must succeed on a DC 13 constitution saving throw or be poisoned. At the start of each of your turns while you are poisoned, you take 3d6 additional poison damage. At the end of each of your turns, you can repeat this saving throw. On a successful save, the poison damage you take on your subsequent turns decreases by 1d6. The poison effect ends when the damage decreases to 0.
