To craft a fermented spider eye in Minecraft, combine one spider eye, one sugar, and one brown mushroom in any slot of your 2×2 inventory crafting grid. This shapeless recipe does not require a crafting table, allowing players to instantly craft it on the fly while exploring.
To successfully craft this alchemical modifier, players must gather three specific items from different environments across the overworld and the Nether. The exact resource details, target biomes, and required collection methods are detailed below.
| Ingredient | Target Biome or Structure | Acquisition Method |
|---|---|---|
| Sugar | Swamps and water borders | Harvest sugar cane and process in 2×2 grid, or defeat Witches |
| Brown Mushroom | Swamps, Mushroom Fields, or the Nether | Break from low-light ground, shear brown Mooshrooms, or harvest huge mushrooms |
| Spider Eye | Dark caves, surface plains at night, or Desert Pyramids | Slay Spiders or Witches directly, or search buried temple chests |
Locating the Ingredients
To gather sugar cane, explore riverbanks, lakes, or ocean shores. Break the stalks by hand. To bypass the farming stage entirely, players can hunt witches near Witch Huts in swamp biomes. Slaying a witch offers a direct chance to acquire both sugar and spider eyes in a single encounter.
For brown mushrooms, navigate to swamps, old growth taiga, dark forest canopies, or the Nether. In these low-light areas, mushrooms grow freely on the surface. If a Mushroom Fields biome is located, break blocks on huge mushrooms to receive multiple brown mushrooms at once.
To obtain a spider eye, wait for nighttime or descend into a cave system. Spiders have a 33.33% chance to drop a spider eye, but only when defeated via a direct player or tamed wolf attack. Environmental damage from fall height, fire, or cacti will yield zero eyes. To bypass early combat, players can explore Desert Pyramids in sandy biomes to search the four hidden loot chests beneath the temple floor.
How to Process Sugar
Open the player inventory screen by pressing E on the keyboard or the designated inventory button on a console controller to access the 2×2 crafting grid. Place a single piece of gathered sugar cane into any single slot of the 2×2 crafting grid. Immediately select the sugar from the output box on the right and drag it into the main inventory slots.
Step-by-Step Crafting Guide
Open the inventory screen to reveal the 2×2 crafting grid. Place the gathered ingredients into the grid as follows:
- One brown mushroom in any slot
- One piece of sugar in any available slot
- One spider eye in any remaining slot
Because this recipe is completely shapeless, players do not need to follow a specific pattern or use a crafting table. Select the finished fermented spider eye from the output slot on the right and place it directly into the inventory bar.
Brewing Recipes and Potion Corruption Paths
Once crafted, this item is primarily used as an alchemical modifier in a Brewing Stand. Open the Brewing Stand interface and place Blaze Powder in the top-left fuel slot to power the stand. Each piece of powder provides fuel for 20 brewing operations. Place the fermented spider eye into the top ingredient slot, then place up to three potion bottles in the bottom three slots to begin the corruption process.
This alchemical process is essential for to weaken enemies or sneak past hostile mobs. While players build massive bases using the to house their alchemical setups, understanding how to utilize the brewing stand is the key to defense. The specific potion transformations are detailed here:
- Potion of Weakness: Combine a fermented spider eye with a standard Water Bottle. This is the only potion in the game that can be brewed directly without using Nether Wart first. This is also the key ingredient path if you want to cure a Zombie Villager.
- Potion of Invisibility: Combine a fermented spider eye with a Potion of Night Vision.
- Potion of Harming: Combine a fermented spider eye with either a Potion of Poison or a Potion of Healing.
- Potion of Slowness: Combine a fermented spider eye with either a Potion of Swiftness or a Potion of Leaping.
Console Commands for Immediate Spawning
Players operating in Creative Mode or with cheats enabled can bypass the survival gathering process by opening the chat console and inputting edition-specific spawning commands. Press the forward-slash key on PC or the designated button on a console controller to open the text interface, then enter one of the following commands:
- Java Edition (1.13 and newer): /give @p fermented_spider_eye 1
- Java Edition (Pre-1.13): /give @p fermented_spider_eye 1 0
- Bedrock and Pocket Edition: /give @p fermented_spider_eye 1 0
