Spider Eye

Spider eye is a poisonous food item. It is dropped by either Spiders or Cave Spiders when killed by the player, but is not dropped by spiders that die from environmental damage (such as a mob grinder). It can be eaten, but will poison the player for four seconds, causing of damage. This damage cannot kill the player (it cannot reduce health below ). Spider eye can also be used in brewing to create mundane and poison potions.

As a Crafting ingredient
Spider eye can be combined with brown mushroom and sugar to craft fermented spider eye.

Trivia

 * Despite the fact that the spider eye is poisonous and can be consumed to slightly replenish hunger, it will only harm a player's health instead of just the player's hunger.
 * Although spider eyes can only produce negative effects for potions to drink, they can be used as an attack when made into a splash potion (brewing gunpowder into a potion will make it a splash potion).
