Have you ever noticed the mysterious cave in the railroad area of Stardew Valley? This cave is part of a post-game quest called the Goblin Problem. In the quest, you will be dealing with the fallout between the Wizard and Witch, who were once married. The Witch isn't an NPC that you interact with, but she can be seen flying above your farm on certain nights, leaving surprises for you.

After completing Goblin Problem, Stardew Valley will reveal a few more of its many secrets to you. This guide will look at the requirements for this quest, how to finish it, and rewards for completion.

Updated April 29, 2023: To help you complete the Goblin Problem quest with ease, we've updated this guide for readability's sake.

Goblin Problem Quest Requirements

Prior to beginning the Goblin Problem quest, there are a few other tasks you will need to do. First, you will need to complete all the Community Center bundles (or JojaMart tasks, depending on which route you choose).

After you have finished completing all the bundles/tasks, you will have access to a ton of post-game content. With the main story finished, head to the railroad area of Stardew Valley. This area is at the very top of the map, directly above Robin's house.

Entering will trigger a cutscene, where the Wizard will talk to you about his ex-wife, the Witch. He will ask for you to find the Dark Talisman, allowing you to enter into the cave and Witch's Hut house to retrieve a bottle of Magic Ink.

How To Complete The Dark Talisman Quest

With the cutscene complete, you can now begin the Dark Talisman quest. To obtain the talisman, you will need to head into the sewers and talk to Krobus.

To get into the sewers, you will first need to obtain the Rusty Key. This is a unique item that you will be rewarded with after donating 60 items to the Museum.

The Rusted Key will permanently unlock the sewers, which can then be accessed by going through the sewer cover in Pelican Town near the graveyard.

After speaking with Krobus, he will grant you access to the Mutant Bug Lair. The Mutant Bug Lair entrance is on the left side of the sewer.

Proceed through the entrance into the area, where you will find a hefty number of enemies. These are mostly Mutant Grubs, with some Mutant Flies that'll fly into you as well.

The path is pretty simple, just continue along until you come to a chest that holds the Dark Talisman.

Now that you have the Dark Talisman, head back to the railroad area and enter the cave.

How To Complete The Goblin Problem Quest

With the Dark Talisman quest complete, you can now begin the Goblin Problem quest. After entering through the cave entrance, you will be on the outside of the Witch's Hut.

Once inside the cave, you will encounter the Henchman. This goblin prevents you from entering the hut, telling you that he isn't able to let you pass. You will have to discover a way to make the goblin move, which can be a bit tricky.

To find out how to get past the Henchman, you can look through lost books at the library.

These books are added to the library collection and can be read at any time. Some of the books are fun additions that are not important, but a few books are relevant to quests in the game.

For this quest, you will need the book 'Goblins' by M. Jasper. Upon reading this book, you will discover that goblins absolutely love Void Mayonnaise. Reading the book is not necessary to finish this quest, but it does give this answer.

To make the Henchman move, just give him some Void Mayonnaise.

How To Obtain Void Mayonnaise

There are a few ways to obtain this strange mayo, so let's take a look at them.

Using A Mayonnaise Machine

The first way that you can obtain Void Mayonnaise is by placing one Void Egg in the Mayonnaise Machine. Void Eggs are laid by Void Chickens, and can also be purchased from Krobus for 5,000g.

Fishing For Void Mayonnaise

When the goblin is present, you are also able to fish Void Mayonnaise from the waters around the hut. If you don't already have one in your inventory, then you will have a 25 percent chance to get one.

Delivering The Void Mayonnaise

After you have the Void Mayonnaise, return to the Henchman and present him with the gift. He will move out of the way, letting you proceed to the hut.

Once inside, grab the Magic Ink. It will be in a purple bottle on the table. Take the ink back to the Wizard's Tower to complete the quest.

You can quickly teleport to the Wizard's Tower from the hut by stepping in the red teleportation rune. This will take you to the basement of the tower, allowing you to quickly give him the Magic Ink.

Completion Rewards

Taking the Magic Ink back to the Wizard's Tower will complete the Goblin Problem quest. This quest unlocks a few different rewards.

Wizard Buildings

This is a set of Wizard-themed buildings that you can now add to your farm. Unlike typical farm buildings, you cannot build these from Robin's Carpenter Shop.

Instead, you will need to interact with the magic book in the main room of the Wizard's Tower.

Dark Shrines

In addition to the Wizard buildings above, you will now have access to three shrines that can be found inside the Witch's Hut.
