This concoction looks, smells, and tastes like a Potion Of Healing or other beneficial potion. However, it is actpally
poison masked by illusion magic. An Identify spell
reveals its true nature.
If you drink it, 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 in this way, you take 3d6 poison 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.
