In Terraria, there are items and bosses that are exclusive to particular biomes – and the Corruption is no exception. Alongside its Crimson counterpart, there are many features to the game that are only accessible in these biomes.

Some of these items are easier to obtain than others and some of these bosses are easier to fight than others.

Worm Food is an example of an item that is relatively easy to obtain but can be an crucial part of your adventure. It is therefore essential to know how to make Worm Food in Terraria, and we’re going to show you how in this guide.

What is Worm Food Used For?

Similar to the Voodoo Doll, Worm Food is used to spawn a certain boss – the Eater of Worlds. The Eater of Worlds is a pre-hardmode boss spawned in the Corruption.

Spawning the Eater of Worlds is simple. You must be in the corruption at any time of the day (knowing how to make it night isn’t necessary as it is with other bosses) and have a hammer, explosives, or Worm Food with you. 

Destroying 3 Shadow Orbs found in the underground Corruption will spawn the Eater of Worlds. It’s worth noting that Shadow Orbs are a finite resource. To destroy these Shadow Orbs, you must use any hammer or explosive. Alternatively, using Worm Food to spawn the Eater of Worlds is easier and can be done as many times as you like – provided you have the required resources.

There are many benefits to defeating the Eater of Worlds. Beating this boss is the only way to obtain Shadow Scales in Terraria, as well as being one of the few ways to acquire large amounts of Demonite ore at a time.

The Eater of Worlds is a worm-like boss of many segments – each of these segments with separate health bars. To defeat this boss, all segments must be killed. Each segment drops a small amount of Demonite ore, and when the entire entity is defeated, a larger amount will drop.

Defeating the Eater of Worlds is an important task because it allows the Tavernkeep to spawn, the Nightmare Pickaxe to be crafted (using 12 Demonite Bars and 6 Shadow Scales – both dropped from the Eater of Worlds), and meteorites to land. The Nightmare Pickaxe is required to mine meteorite.

Tips for Defeating the Eater of Worlds

The Eater of Worlds is a large, multi-segmented boss, meaning that attempting to dodge it may prove a challenge. Therefore, full preparation is recommended in order to compensate for the extra damage from not dodging. 

Due to the fact that there is typically a large underground cave in the Corruption, little block breaking is generally required. However, it is still good practice to take explosives to the Corruption caves to ensure maximum space is made (since ebonstone blocks cannot be mined with any pre-hardmode pickaxe).

Once you’ve cleared space with the explosives, it’s best to make multiple layers of platforms, going across the entirety of the space made. The vertical difference between each platform layer should be 4 or 5 tiles – low enough to default jump onto.

Prepare your platform boss-battling arena by ensuring campfires and heart lanterns are scattered around. These will assist your health regeneration. On top of this – particularly if you are playing the mage class setup – placing Stars in Bottles will increase mana regeneration.

Make sure you always carry at least a stack of the highest-tier healing potion available – and have potions bound to a hotkey. Having potion use bound to a hotkey is very important as it allows quick use from anywhere – without having to go into inventory and do it all manually mid-fight.

If you are a magic-user, make sure you also carry at least a stack of the highest-tier mana-potions available to you.

Finally, it’s worth noting that went a segment dies, the segment in front and behind it will form together as a new worm – with a head and a tail. It’s important to remember to prioritize attacking the heads of the extra worms as they deal the most damage, but also have the least defence.

How to Get Worm Food

Worm Food is a relatively easy item to obtain, especially considering the impact that using it can have on your game. It’s a craftable boss-summoning item and can only be crafted at a Demon Altar or Crimson Heart.

Demon Altars and Crimson Hearts are found in the depths of their respective biomes and there are several found per map. Upon being broken, Demon Altars and Crimson Hearts will drop an item exclusive to its biome.

The resources required are 30 Vile Powder and 15 Rotten Chunks (per 1 Worm Food). 

Vile Powder can be crafted at any workbench using Vile Mushrooms. Vile Mushrooms are commonly found on grass in the Corruption – where they can be harvested by 1 swing of any weapon or tool. A Vile Mushroom will create 5 Vile Powder meaning that, in total, you need 6 Vile Mushrooms to craft the required amount of Vile Powder for Worm Food.

Additionally, Vile Powder can be purchased from the Dryad NPC for 1 silver each during a Blood Moon in a Corruption world.

On top of being an ingredient for Worm Food, it can be used to turn any block into their Corruption equivalent – including being able to convert Hallowed and Crimson blocks. When thrown at a bunny, penguin or squirrel, they will turn into their Corrupt counterparts. 

Rotten Chunks can also be acquired in the Corruption. They have a chance of dropping from Devourers, Eaters of Souls, and Corruptors. The drop-rate of Rotten Chunks is 33%, for all of the mentioned enemies.


To conclude, Worm Food is a very important boss-spawning item in Terraria that – upon successfully defeating its respective boss – can reap many rewards.

It is simple to make – requiring only Rotten Chunks and Vile Powder – and is almost exclusive to Corruption worlds.
