How to make a Potion of Weakness in Minecraft

Potions have many uses, both positive and negative. A potion of weakness will lower your attack power making you do less damage with melee weapons. The effect of this potion can be upgraded to last longer but a “Weakness II” potion cannot be brewed. There are not many advantages for potion of weakness on its own. However, its splash potion variant can turn a downside into an upside. You can also use potions of weakness to cure zombie villagers.

Where to find Potion of Weakness?

Potion of weakness can be found in the creative menu three slots below flint and steel.

They are next to potions of strength and potion of decay.

Required Ingredients for Potion of Weakness:

To make Potion of weakness, you will need:

  1. Fermented Spider Eye
  2. Water Bottle
  3. Brewing Stand
  4. Blaze Powder
  5. Crafting table

The recipe for potion of weakness is simpler than most potions. It does not require brewing an awkward potion as a base. Its primary ingredient: fermented spider eye can be difficult to make as it requires brown mushrooms.

You will need glass bottles and a water source in order to make water bottles. Dig up some sand and smelt it in a furnace to get the glass needed to make glass bottles.

To brew your potion you will need a brewing stand. The hardest part of this step is finding a nether fortress to locate a blaze rod.


Finally, you will need blaze powder to fuel your brewing stand. If you have found a nether fortress with a blaze spawner you should have no trouble acquiring blaze powder.

You will need the 3x3 crafting menu of a crafting table in order to finish some of these recipes.

How to make Potion of Weakness?

Let’s start by locating a brown mushroom. I find the most consistent method is to find a dark oak forest biome. Brown mushrooms can spawn where it is dark enough, you could check caves, or even the nether. Dark oak forest biomes will generate tall brown mushrooms so they are easy to spot and will give you more than enough. It is also safer than dark caves and the fiery nether.

You can recognize dark oak forest biomes from its 2x2 trees and the tall mushrooms sprouting between the trees. Once you have found a tall brown mushroom, you can break it down with just your hands and every block has a chance to drop some brown mushrooms. If finding a dark oak forest proves too difficult you can also find brown mushrooms in a swamp.

For fermented spider eye, the recipe calls for specifically brown mushrooms. Next, you will want to locate some sugarcane. They can be found commonly along riversides and always adjacent to a water source block.

Sugarcane can grow on dirt or sand. Harvest some and start looking for spiders. Spider eyes are a rarer drop than string so keep a sword ready and track down some spiders.

Turn some sugar cane into sugar by placing it into a crafting menu.

You will need to track down some blaze to fuel your brewing stand. Blaze will only spawn near a nether fortress. Try to avoid their fireball projectiles, take it slow, and gather as many blaze rods as you can.

Minecraft overworld

Take your blaze rods back to the overworld and gather some cobblestone. Place three cobblestone along the bottom and the blaze rod above it in the middle to craft a brewing stand.

Place your brewing stand somewhere safe. All that is left is to make your glass bottles. Dig up some sand and smelt it in a furnace to make at least three pieces of glass.

With your glass bottles in hand right click any water source to fill it up with water bottles. Place these water bottles in the bottom slots of your brewing stand. Your blaze powder will be used to fuel your brewing stand. Place the blaze powder in the top left slot.

Now you will be rewarded with 3 Potions of weakness. These potions will inflict weakness for a minute and thirty seconds. You can extend this time by placing redstone above these potions in a brewing stand.

Use these with caution. As they are now you can only drink them yourself which will make your melee attacks do less damage. In bedrock edition the debuff is only 0.5 hearts less. In java edition it will make you deal two whole hearts less damage.



Congratulations! You have successfully brewed a relatively niche potion. These potions will make you do less damage so if you would like to impose a challenge on yourself this is a good way to do so. They can also be upgraded to last longer or become splash potions which you can use to inflict on other enemy mobs. Weakness is a detrimental effect but splashing your opponents with it can give you an advantage.
