Quick Answer

Open a Police auction in your highest affordable area, pick up a Redacted item and let the police arrest you. Talk to Mike in Jail, collect a Home Carpet and several Spoons, then return to finish the escape. Start his Back Alley Bank Heist conversation, come back with 1,575 Luck and accept The Onyx Contract before farming all 337 required mutation items.

What You Need Before Starting

The Onyx Contract sits behind Mike's jailbreak sequence, so prepare the escape items before making repeated trips to Jail. Your quest tracker asks for one Spoon, but the digging minigame can break Spoons during the escape.

RequirementWhere to get itWhat to know
Police auctionYour highest affordable auction areaLook for caution tape around the auction
Redacted itemInside a Police auctionPick it up to gain the wanted level needed for arrest
Home CarpetBack Alley auctionsRaise your Luck before farming it; start around 100% and adjust your setup if needed
SpoonsJunk Yard auctionsBring roughly 5-8 so broken Spoons do not end the escape attempt
1,575 LuckAccessories, drinks and other active bonusesRequired when asking Mike about Onyx in Back Alley
Tip: Farm the Home Carpet and spare Spoons before your second arrest. Jail visits are brief, and leaving to replace a broken Spoon means repeating the arrest route.

How to Find Mike in Jail

Police auctions appear in the best auction area your current progression can support. Check that area for an auction marked with caution tape, open it and take a Redacted item. When the police begin chasing you, stop running and let them arrest you.

  • Go to the highest area you can currently afford to use consistently.
  • Scan its auction buildings for police tape rather than checking every normal auction.
  • Open the Police auction and pick up a Redacted item to raise your wanted level.
  • Let the pursuing police catch you so you are transported to Jail.
  • Talk to Mike immediately and accept Jailbreak Supplies before the Jail visit ends.
Warning: Do not spend the short Jail window searching menus or inventory. Go straight to Mike, take the quest and prepare the requested items outside Jail.

How to Break Mike Out of Jail

Jailbreak Supplies asks you to find a Spoon and a Home Carpet. Once both objectives are ready, trigger another arrest through a Police auction, return to Mike and place the carpet in the cell to begin digging.

  • Farm Spoons in Junk Yard; lowering Luck can make it easier to see common auction items instead of rarer replacements.
  • Farm the Home Carpet in Back Alley with a useful Luck setup equipped.
  • Carry several spare Spoons even after the tracker marks its one-Spoon objective complete.
  • Get arrested again, talk to Mike and place the Home Carpet at the digging point.
  • Complete the dirt-block minigame, replacing broken Spoons until the tunnel opens.
  • Talk to Mike outside the tunnel to finish the escape and receive the permanent +7% Luck reward.
Tip: Treat 5 Spoons as a practical minimum and bring more when possible. The exact number consumed depends on how the digging attempt goes.

How to Unlock the Onyx Conversation

After the escape, Mike moves to Back Alley near the graffiti and auction area. Talk to him and begin his Bank Heist quest. You only need to open that quest line for the Onyx conversation to appear; the four-C4 heist does not need to be completed first.

  • Follow Mike's post-escape cutscene or head to his Back Alley position.
  • Start the Bank Heist conversation, then speak to Mike again.
  • Equip your strongest Luck accessories and activate drinks before choosing the Onyx option.
  • Reach at least 1,575 displayed Luck and accept The Onyx Contract.
  • Check that all ten objectives appear in the tracker before opening more auctions.
Warning: The 1,575 Luck requirement only unlocks the contract conversation. You still need to find every mutation item after the contract is active.

Complete Onyx Contract Checklist

The contract covers the full standard mutation ladder from Silver through Rainbow. In total, you need to find 337 qualifying items after accepting the quest.

MutationItems neededRunning total
Silver100100
Gold75175
Corrupted50225
Diamond35260
Gem25285
Chrome20305
Hologram15320
Void10330
Secret5335
Rainbow2337
Tip: Do not assume Rainbow will always finish last. Mutation-specific luck can leave a mid-tier target such as Chrome, Gem or Diamond as your final objective.

Best Way to Farm the Mutation Checklist

Use an area you can clear repeatedly without draining your cash. Business Bay works for wealthy players because every auction can also produce valuable side finds, but a cheaper area is better when high bids would interrupt the grind.

  • Equip gavels that improve the mutation currently falling behind on your tracker.
  • Keep a mixed set of Silver-through-Rainbow gavels instead of building only for the rarest mutation.
  • Use Luck drinks during focused sessions rather than letting their timers run while sorting your shop.
  • Check the tracker after each group of auctions and swap gavels as objectives finish.
  • Sell or store completed mutation tiers quickly so your vehicle and shop do not become the bottleneck.
  • Keep bidding discipline: the contract counts finds, not profit, but running out of cash stops both.
Tip: Plan for several focused sessions rather than one short run. Optimize the mutation that is actually behind, not the one that looks rarest on paper.

Claim Onyx and Use It in Auctions

When all ten counters are complete, return to Mike in Back Alley and claim The Onyx Contract. Onyx then joins the mutation pool in the same auction areas where you find standard mutations and applies a 175x value multiplier.

  • Confirm the quest tracker shows every objective complete before leaving your farming area.
  • Talk to Mike and claim the reward rather than assuming completion unlocks it automatically.
  • Keep your Luck setup equipped when hunting for the first Onyx item; unlocking it does not make it common.
  • Use the calculator to compare an Onyx item's final value after markup, condition and any additional mutations.

Onyx Quest Mistakes to Avoid

Most failed attempts come from entering Jail unprepared or starting a long farming session before the contract is active. Check each gate in order and you will avoid repeating the slowest parts.

  • Looking for Police auctions in an area above or below your current best affordable tier.
  • Running from the police after gaining the wanted level instead of allowing the arrest.
  • Returning to Jail with only one Spoon and losing it during the digging minigame.
  • Trying to finish the entire Bank Heist before checking Mike's Onyx conversation.
  • Using Luck drinks before you are ready to talk to Mike or begin auction farming.
  • Farming mutation items before confirming The Onyx Contract is visible in the tracker.

Storage Hunters: Open World Guide FAQ

How do you start The Onyx Contract in Storage Hunters?

Free Mike from Jail, find him in Back Alley and start his Bank Heist quest. Talk to him again while you have at least 1,575 displayed Luck, choose the Onyx conversation and confirm the contract appears in your tracker.

How many items do you need for The Onyx Contract?

You need 337 mutation items in total: 100 Silver, 75 Gold, 50 Corrupted, 35 Diamond, 25 Gem, 20 Chrome, 15 Hologram, 10 Void, 5 Secret and 2 Rainbow.

Where do Police auctions spawn?

Look in the highest auction area your progression can currently afford. Police auctions are marked by caution tape. Open one, pick up a Redacted item and let the police catch you to reach Jail.

How many Spoons should you bring to free Mike?

The quest tracker asks for one Spoon, but Spoons can break during digging. Bring about 5-8 from Junk Yard so a broken tool does not force you to leave Jail and repeat the arrest route.

Do you have to complete Mike's Bank Heist before Onyx?

No. Start the Bank Heist quest so Mike's next conversation becomes available, then talk to him again with 1,575 Luck. You do not need to finish the four-C4 heist before accepting The Onyx Contract.

What does completing The Onyx Contract unlock?

Claiming the completed contract from Mike unlocks Onyx in the normal auction mutation pool. Onyx multiplies item value by 175x, but it remains rare after the unlock.
