How To Get Krobus To Move In: The Ultimate Stardew Valley Roommate Guide

Securing Krobus as your permanent roommate in Stardew Valley requires donating at least 60 unique items to the Museum to acquire the Rusty Key, navigating the Sewers, and offering a Void Ghost Pendant. This process bypasses traditional marriage mechanics, allowing you to live with the shadow person platonically without jealousy or divorce proceedings.

Prerequisites and Unlock Criteria

Achieving this unique living arrangement requires careful preparation and adherence to specific game milestones. Because Krobus is not a marriage candidate in the traditional sense, you cannot use a standard Bouquet or Mermaid's Pendant. Instead, you must unlock deep-game content and build a strong platonic relationship with Pelican Town's sole resident shadow merchant.

• Required Tools and Materials: The Rusty Key (unlocked via Museum donations) and a Void Ghost Pendant (crafted from 200 Void Essence and a Void Salmon, or purchased from the Desert Trader).
• Prerequisite Knowledge: You must reach 10 hearts of friendship with Krobus specifically. Friendship decay is disabled for roommates, meaning once you move him in, your status remains locked at max friendship unless you actively choose to evict him.
• Time and Resource Benchmarks: Reaching 60 museum donations typically takes anywhere from Year 1 to Year 3 depending on mining efficiency. Gifting Krobus twice a week with universally loved items will take approximately 4 to 8 in-game weeks to bridge from initial meeting to 10 hearts.

Step-by-Step Guide to Relocating Krobus

Step 1: Unlock Access to the Sewers

To even begin interacting with Krobus regularly, you must gain entry to the Pelican Town Sewers. This requires donating a total of 60 items (artifacts and minerals) to Gunther at the Museum. Once the threshold is met, Gunther will visit your farmhouse the following morning to hand you the Rusty Key. Head to the southern grate in Pelican Town or the drainpipe in the Cindersap Forest to unlock the heavy door leading into the Sewers, where Krobus operates his shop.

Pro-Tip: Keep a stash of duplicated minerals and common artifacts in chest storage rather than selling them immediately, ensuring you can quickly hit the 60-item threshold once your mining levels stabilize.

Step 2: Maximize Friendship to 10 Hearts

Initiate a gifting routine to raise your friendship with Krobus from zero to the maximum ten hearts. Krobus is an NPC with distinct tastes who appreciates items related to the void, monster drops, and rare foraged goods. Deliver gifts twice a week, and remember to speak to him daily to maximize point gains.

Warning: Do not gift Krobus items he dislikes, such as most standard flowers, cooked dishes containing fish, or eggs, as this will slow your progress significantly.

Step 3: Acquire the Void Ghost Pendant

Unlike a human spouse who accepts the Mermaid's Pendant during rainy weather on the Beach, Krobus requires a Void Ghost Pendant to move in. To obtain this item, you must visit the Desert Trader in the Calico Desert. Trade 200 Void Essence—farmed efficiently from Shadow Brutes and Shadow Shamans in the Mines or mutant bugs in the Mutant Bug Lair—in exchange for the pendant. Alternatively, you can craft it if you purchase the recipe or trigger the necessary desert conditions, but trading is the standard method.

Step 4: Propose to Krobus and Finalize the Move

With the Void Ghost Pendant in your inventory and your friendship standing firmly at 10 hearts, travel into the Sewers and present the pendant to Krobus. He will accept your proposal with surprise and gratitude, noting that shadow people do not typically live among humans. Three days after your proposal, Krobus will pack up his shop in the Sewers (though a mail-order chest will remain in his place so you can still buy items from him) and move into a specialized room attached to the right side of your farmhouse.

Roommate Mechanics and Lifestyle Adjustments

Living with Krobus introduces distinct gameplay mechanics that separate this arrangement from traditional marriage. Understanding these parameters ensures your farm runs smoothly without unexpected surprises.

Common Site Failures and Field Fixes

Even with careful planning, players occasionally encounter roadblocks when attempting to transition Krobus from vendor to roommate.

• Root Cause: The proposal option does not appear when interacting with Krobus despite having 10 hearts.
  
  
  • Actionable Fix: Ensure you actually have the Void Ghost Pendant in your active inventory slots rather than stored in a chest or fridge. Additionally, verify that your farmhouse has been upgraded at least once to include the nursery or extra rooms necessary to house a resident.
• Root Cause: Krobus's shop inventory disappears entirely after he moves into the farmhouse.
  
  
  • Actionable Fix: This is a common misconception; Krobus does not stop selling items. He simply leaves a small mailbox chest behind in the original Sewers location where you can still browse his weekly inventory and purchase void eggs, solar essences, and monster items.
• Root Cause: Inability to initiate divorce or eviction proceedings if you decide to change living arrangements.
  
  
  • Actionable Fix: Head to Mayor Lewis's Manor and interact with the ledger book. You can choose to evict Krobus for a fee of 50,000 gold, which returns him permanently to the Sewers and resets your friendship to five hearts.

Frequently Asked Questions

Can I still marry a villager if Krobus is my roommate?

Yes. Krobus acts as a roommate rather than a legal spouse, meaning the jealousy mechanic is entirely disabled. You can maintain platonic cohabitation with Krobus while dating or even marrying any eligible bachelorette or bachelor in Pelican Town without penalty.

Where does Krobus go during festivals and town events?

Krobus generally stays inside your farmhouse during most community festivals and public events because shadow people are sensitive to bright sunlight and large crowds. However, he will occasionally make rare appearances at specific outdoor night markets or secluded festival zones depending on game updates.

Does Krobus help around the farm like a human spouse?

While Krobus will not water crops or feed animals in the traditional marriage rotation, he contributes uniquely by cooking full meals for you, locking down the house at night, and occasionally decorating your shared living space with strange, eldritch items.

What happens to my items if I decide to evict Krobus?

If you choose to evict Krobus using the book at Mayor Lewis's Manor, he will immediately move back to the Sewers. Any unique furniture or items inside his custom room extension will be safely transferred into your inventory or lost if there is no remaining space, so clear out the room beforehand.

Can Krobus catch the flu or experience friendship decay?

No. Once Krobus moves in as your roommate, his friendship level is permanently locked at 10 hearts (2500 points). Friendship decay is entirely disabled, meaning you do not need to speak to him or give him gifts daily to maintain maximum status.

Mastering the mechanics of bringing Krobus into your farmhouse opens up one of Stardew Valley's most rewarding and unique domestic partnerships. Optimize your Museum donations, stockpile your Void Essence, and enjoy a quiet, stress-free household dynamic today.
