The extended Potion of Poison (2:00) inflicts the Poison effect for 2 minutes, gradually reducing the target's health over an extended period without killing them. It is brewed by combining a Potion of Poison (2:00) (0:45) with Redstone Dust in a Brewing Stand. This Potion of Poison (2:00) is useful for sustained weakening of enemies during combat, leaving them vulnerable for a longer time. Like its shorter version, it does not affect undead mobs such as Zombies and Skeletons, which are immune to Poison.
