Crafting Recipe for Fermented Spider Eye

Making a fermented spider eye in Minecraft requires three simple ingredients that you can combine at any crafting table. You’ll need one spider eye, one brown mushroom, and one sugar. The arrangement doesn’t matter – just place all three items anywhere in the 3×3 crafting grid and you’ll get your fermented spider eye.

Where to Find the Ingredients

Spider eyes drop from spiders when you kill them, though the drop rate isn’t 100%. You might need to hunt several spiders to get one. Brown mushrooms grow naturally in dark areas like caves, swamps, and the Nether. They’re also found in mushroom biomes. Sugar comes from sugar cane, which you can craft by placing sugar cane in your crafting grid.

What Fermented Spider Eyes Are Used For

This brewing ingredient serves as a corrupting agent that transforms beneficial potions into harmful ones. When you add a fermented spider eye to a potion of healing, it becomes a potion of harming. A potion of swiftness turns into slowness, and night vision becomes invisibility. It’s also essential for brewing potions of weakness, which are crucial for curing zombie villagers.

Brewing Applications

In the brewing stand, fermented spider eyes work differently than most ingredients. Instead of enhancing effects, they corrupt existing potions or create entirely new negative effects. You can brew a potion of weakness by combining a fermented spider eye with a water bottle, making it one of the few potions that doesn’t require nether wart as a base.

The fermented spider eye represents one of Minecraft’s most versatile brewing ingredients, opening up possibilities for both offensive potions and essential utility brews like weakness potions for villager curing.

TL;DR

Craft a fermented spider eye by combining one spider eye, one brown mushroom, and one sugar in any crafting table arrangement. This ingredient corrupts beneficial potions into harmful ones and creates weakness potions.
