Potion of Poison

This concoction looks, smells, and tastes like a potion of healing or other beneficial potion.
However, it is actually poison masked by illusion magic. An identify spell reveals its true nature.
If you drink it, you take damage, and you must succeed on a saving throw or be poisoned. At the start of each of your turns while you are poisoned in this way, you take damage. At the end of each of your turns, you can repeat the saving throw. On a successful save, the poison damage you take on your subsequent turns decreases by 1d6. The poison ends when the damage decreases to 0.
For convenience, you can use these enrichers ( or ) to perform the damage roll for the reduced damage.
