If the crafting of a poison goes wrong, this is created. It looks identical to the poison that the player attempted to create, and a character must succeed on a DC 15 INT check to see that it is actually a failed poison. The poison is applied normally, but when the target would be affected, roll a d20 and use that effect instead.
