Boxwood Oil

Potion, Very Rare
As an action you can apply the oil to your weapon or up to 5 pieces of ammunition, the effects of the oil last for 1 hour. A creature hit with the poisoned weapon or ammunition takes 4d8 poison damage and must make a DC 16 Constitution save or be poisoned. A creature affected this way takes 4d8 poison damage at the start of its turn. At the end of each of its turns, it can repeat the saving throw. On a successful save, the poison damage it takes on subsequent turns decreases by 1d8. The poison ends when the damage decreases to 0.
