Piglins, a hostile mob in the Minecraft world, are primarily afraid of water.
This fear stems from their natural habitat, the Nether, a dimension devoid of water. Piglins are ill-equipped to deal with water, and it can even harm them.
However, Piglins are also wary of players who are not wearing golden armor. This is because they are known for their love of gold and will attack players who they perceive as a threat to their gold.
Lastly, Piglins are susceptible to the effects of potions, particularly those with negative effects like poison and weakness. These potions can significantly weaken them, making them easier to defeat.
