Storage Hunters: Open World Mutations and Their Value Multipliers

Mutations are visual modifiers that roll on the items you pull from storage lockers in Storage Hunters: Open World, and they directly change how much each item sells for. Most raise the price, a few raise it dramatically, and one actually lowers it. Knowing which mutation you are looking at, and what it multiplies your base value by, is the difference between a break-even locker and a five-figure flip.

Quick answer: Void applies the highest obtainable multiplier at 35x, while Dirty is the only mutation that hurts you at 0.8x. Multiple mutations on one item stack additively, so Silver (2x) plus Gold (4x) totals 6x, not 8x.

How mutations change an item’s sell value

Every item has a base value, and a mutation multiplies that value before the game applies item condition and grade. A single Pure mutation on a $565 Scrap Dominus pushes its sell price up by 1.5x, which is meaningful on its own. The rarer mutations multiply by far more, which is why high-base-value items with a strong mutation can sell for a fortune.

When an item carries more than one mutation, the multipliers add together rather than multiply. A Silver and Gold combination produces 6x because 2 plus 4 equals 6. This additive rule matters when you plan stacks, because chasing two mid-tier mutations rarely beats a single top-tier one.

All mutations and their multipliers

There are more than 20 documented mutations in the game. The table below lists each one with its value multiplier, ordered from the lowest payout to the highest.

Void at 35x is the clearest high-ceiling pick for expensive items, and Hologram, Chrome, and Timeless form the next tier worth chasing. Black is currently unobtainable, and Rainbow’s exact multiplier has not been confirmed yet.

Weather-locked mutations

Some mutations only become more likely during specific weather events, so timing your sorting around the weather can change which mutations you roll.

How to increase your mutation chances

Every time you win an auction and sort the items, each one has a random chance of rolling one or more mutations. You can raise those odds with a few systems built into the game.

Certain accessories also raise your luck, which feeds into the same mutation roll. Equipping luck-boosting gear before sorting compounds with placed Gavel Trophies.

Stacking multiple mutations on one item

An item can carry more than one mutation, but it rarely happens by chance. Natural multi-mutation rolls are uncommon, so the dependable routes are Gavel Trophies with multiplier mutations and the Time Capsule. Because multipliers add rather than multiply, plan stacks around raising the total instead of expecting a runaway score from two small mutations.

Removing the Dirty mutation

Dirty is the only mutation worth removing, since its 0.8x multiplier sells the item for less than its clean base value. Take the Dirty item to the Cleaning Shop inside the Shopping Mall to strip the mutation and restore full value. No other mutation can be removed, so the value-boosting ones are permanent once they roll.

Note: Treat a Dirty roll as a discount signal rather than a reason to overbid. Even after cleaning, the item is only worth its normal base value.

The practical takeaway is to pair high-base-value items with the strongest mutation you can manage. A 35x Void on a cheap item still nets little, while a mid-tier mutation on a top-value find can pay off far more. Build your luck with Gavel Trophies and accessories, time your sorting to the weather, and save the Time Capsule for the items most worth boosting.
