When it comes to potion ingredients for all that wild and wacky concoction you may be thinking of brewing, Fermented Spider Eye in Minecraft is one of the most useful items in the game. Fermented spider eyes are capable of turning potions into their opposite effects. If you have not brewed potions before, it can be difficult to get used to the recipes. Here is a quick guide to help you craft fermented spider eyes and make very powerful potions.

What is a Fermented Spider Eye?

Well, besides the sarcastic obvious answer the fermented Spider Eye is an item used in brewing alongside brown sugar to create an item that can make Potions of weakness when you brew it into a bottle of water. The fermented spider eye is not edible, not that you should ever think of snacking down on one,

You can collect spider eyes by killing the nasty bugs

To get spider eyes, you need to farm spiders. Unlike items such as string, the drop rate for spider eyes is much lower but you should not have too much trouble getting them.

Sugar can be acquired by farming sugarcane. Simply put sugarcane in the crafting menu and you will be able to turn it into sugar.

Where to find brown mushrooms in Minecraft

Do note that only brown mushrooms work and other variants of mushrooms do not work.

In case you do not have any brown mushrooms, try looking in dark oak biomes, swamps, and dark caves which are usually laden with mushrooms. Basically, head for shady areas and you will find some brown mushrooms soon enough. If you simply cannot find any, then Nether biomes are usually overrun with this particular fungus.

Once you have all the ingredients, place them in the crafting grid in any arrangement.

What potions can you make with Fermented Spider Eye?

  • Potion of Harming: Fermented Spider Eye + Potion of Healing/Poison
  • Potion of Invisibility: Fermented Spider Eye + Potion of Night Vision gives you three minutes of invisibility at basic level
    (Note to make a Potion of Night Vision you need Nether Wart, a golden carrot, and a water bottle)
  • Potion of Weakness: Fermented Spider Eye + Water Bottles – This causes mobs to hit you with less damage (reduced by 1, or by 4 in Java edition)
  • Potion of Slowness: Fermented Spider Eye + Potion of Swiftness/Leaping – this splash potion will slow your enemies down by a minumum of 15% at its lowest enchantment level.
    (Note: Potion of Swiftness is made with Netherwart, Sugar, and a water bottle. Potion of Leaping can be made with Netherwart, a Rabbit’s Foot, and a water bottle.

We recommend brewing all of the potions as they can be very fun to play with. If you love alchemy and the creation of potions in Minecraft, we recommend getting as many fermented spider eyes as possible. Most potent poison brewing requires netherwart, gunpowder, glow stones, and fermented spider eyes. You also get a small number of experience points as well.

All potions apart from the Potion of Invisibility have negative effects that affect melee damage.

In case this is your first rodeo when it comes to alchemy in Minecraft you might well find this next section a lot of use too…

To cook up any of the above potions in Minecraft you are going to need a brewing stand in your inventory. To knock one of these up you will need the following.

  • 3 x Cobblestone
  • 1 x Blaze Rod

Now cobblestone is in plentiful supply but the Blaze Rod is going to be a little tricker to get your blocky hands on.

How to get a Blaze Rod in Minecraft

To get hold of a Blaze Rod you will need to venture into the Nether and defeat some Blazes. The rod should drop easily after that. Once you have one, hit up your crafting table and place three cobbletone on the botoom row and the Blaze Rod directly above in the center.

If you don’t wish to venture into the nether you will occasionally find Brewing Stands in Village Churches or Igloos, so if there are any in the vicinity right now, that may well turn out that looting here will be a quicker way to start your home brewing empire.
