Potion of Poison (2:00) inflicts a poison effect on the player or entity it is used against, gradually reducing health over a period of two minutes. Unlike most damage sources, this potion cannot kill but can reduce health to a minimum of one half-heart. It is typically brewed by adding a spider eye to an Awkward Potion and can be thrown as a splash potion or enhanced to create a Potion of Poison II for a shorter, more potent effect.
