The Splash Potion of Harming (II) deals 12 damage (6 hearts) instantly to players and mobs within its splash radius. It is brewed by adding Gunpowder to a Potion of Harming (II) in a Brewing Stand. This enhanced version is a powerful weapon for quickly weakening or eliminating enemies, especially in group combat scenarios. However, it is ineffective against undead mobs, such as Zombies or Skeletons, which are immune to its effects. Careful use is recommended to avoid accidentally harming allies or yourself.
