Spider Eye

Spider eye is a poisonous food and brewing 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). Spider eyes are mainly used to craft fermented spider eyes and brew mundane and poison potions. 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 ).

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 often 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).
