Mutation Values
Storage Hunters: Open World mutation values and multipliers.
Use this Storage Hunters: Open World mutations guide to check confirmed multiplier values, event sources, Time Capsule chances, Limited Passive values, Museum effects and calculator notes before pricing a mutated item.
Quick Read
How mutations affect Storage Hunters item value
A mutation changes the multiplier side of the Storage Hunters: Open World value formula. For players, the practical question is simple: is the item worth hauling, selling, or checking again in the calculator? Start with the item base value, add the confirmed mutation multiplier, then account for condition and grade.
Best for quick checks
Standard mutations such as Gold, Diamond, Void, Secret, Rainbow and Onyx are the fastest values to compare when an auction item looks unusually expensive.
Watch event-only effects
Rain, Moonlit, Acid Rain, Nuclear Meltdown, Sandstorm, Alien Invasion, Wild West and Police mutations come from their matching event windows. Unknown drop chances are labeled.
Separate special rolls
Washing, Time Capsule, Limited Passive and Museum mutations are separated because their sources and effects differ from normal auction mutation checks.

Standard Mutations
Standard mutations are the main value effects players compare during auctions and shop checks. Use these multipliers when an item already shows a confirmed mutation and you want to estimate its sell value.
Event Mutations
Event mutations are only obtainable while their event is active. Event mutation chances can be boosted with Luck Drinks, but the mutation still needs to come from the matching event window. Only mutations with confirmed fixed multipliers are available in the calculator; variable and pending entries remain reference-only.
Moonlit Event
The Moonlit Event lasts 4 minutes.
Rain Event
The Rain Event lasts 8 minutes.
Acid Rain Event
The Acid Rain Event shares the Wet and Shocked mutation pool with the standard Rain Event. Acid and Caustic are exclusive to Acid Rain.
The Acid Rain Event lasts 4 minutes.
Nuclear Meltdown Event
The Nuclear Meltdown Event shares the Wet and Shocked mutation pool with Rain. Radioactive and Nuclear are exclusive to Nuclear Meltdown.
The Nuclear Meltdown Event lasts 4 minutes.
Sandstorm Event
The Sandstorm Event produces the 12.5x Dune and 2.25x Sandy mutations.
Police Event
The Police Event produces Redacted and Seized mutations. Their drop chances have not been confirmed yet.
Limited Event Mutations
Event mutations are only obtainable while their event is active. Event mutation chances can be boosted with Luck Drinks, but the mutation still needs to come from the matching event window. Only mutations with confirmed fixed multipliers are available in the calculator; variable and pending entries remain reference-only.
Alien Invasion Event
The Alien Invasion Event produces Probed, Abducted and Extraterrestrial mutations during the limited event.
Wild West Event
Wild West mutations are obtainable during the limited Wild West event. Their drop chances are not yet confirmed.
Washing Mutations
Items carrying Dirty can be washed once, removing Dirty with a chance to receive Pure or Spotless, or no washing mutation. Mint items can also be washed, with a Luck-based chance to receive Perfect.
Time Capsule Mutations
The Time Capsule can apply one of four special mutations to an item. After an item is placed into the Time Capsule, it rolls every 5 minutes until one of the Time Capsule mutations is selected. Only one Time Capsule mutation is applied, so treat this as a separate upgrade path rather than a normal auction mutation pool.
The total chance to receive any Time Capsule mutation on a roll is 3.125%. Since the Time Capsule keeps rolling until one of the four mutations is selected, the final chance is based on each mutation's share of that total. This is why Cobwebbed is much more common than Timeless even though all four belong to the same Time Capsule system.
Limited Passives Mutations
Limited Passive mutations can appear only when the player is wearing accessories that provide a mutation chance passive. The chance depends on the stats of the equipped accessories, but confirmed multiplier values can still be used in the calculator.
Museum Mutations
Museum mutations come from the display and gift system rather than normal item rolls. Their effects are shown for reference and stay out of calculator candidates.
Special notes
Mint is reported as 1x plus a customer tip, but the tip formula is not confirmed yet, so it is not included in the calculator selector. Museum effects are also excluded from calculator and guesser candidates because they modify display Luck rather than item value.
Calculator notes
How to use this mutation table with the calculator
Calculator results use confirmed mutation multipliers with the current Storage Hunters: Open World item value formula: base item value, automatic markup, mutation multiplier, dynamic floor, condition multiplier and grade multiplier. Fossil is included as a calculator-ready 5x mutation. Unconfirmed special effects stay out of calculator candidates until their math is clear.
- Use the item wiki to confirm the base value before applying a mutation multiplier.
- Use the price calculator when you know the item, condition and mutation.
- Use the mutation guesser when you only know the shelf price and want to compare likely mutation candidates.
FAQ
Storage Hunters mutations FAQ
What are mutations in Storage Hunters: Open World?
Mutations are item effects that can change item value or provide special effects. Standard, Event, Washing, Time Capsule, Limited Passive and Museum mutations each have their own source and rules.
Which Storage Hunters: Open World mutations can be used in the calculator?
The calculator uses mutations with confirmed fixed numeric multipliers. Mint, Showcased and Artifact stay out of price calculations because they use a customer-tip formula or display-only Luck effects.
Do event mutations work the same as standard mutations?
Event mutations use normal multiplier values after they are obtained, but their availability depends on matching events such as Rain, Moonlit, Acid Rain, Nuclear Meltdown, Sandstorm, Alien Invasion, Wild West or Police.
Why are Time Capsule mutations listed separately?
Time Capsule mutations have special roll behavior and final-chance math, so they are separated from normal mutation pools to avoid confusing them with standard auction mutations.
What is the Fossil mutation in Storage Hunters: Open World?
Fossil is a 5x Limited Passive mutation. It is tied to accessories with mutation chance passives, so its chance depends on the equipped accessory stats.
