The Splash Potion of Poison (II) applies an intensified Poison effect to players and mobs within its splash radius for 21 seconds. It is brewed by adding Gunpowder to a Potion of Poison (II) in a Brewing Stand. This potion causes faster health reduction compared to the standard Poison effect, making it highly effective for quickly weakening enemies in combat. Like other Poison effects, it does not harm undead mobs, such as Zombies or Skeletons. The splash functionality allows for easy application to multiple targets, making it a potent tool for tactical use in battles.
