With 24 mutations in Storage Hunters: Open World, not all mutations are created equal. Some multiply your earnings by 50x, while others actually reduce your item's value. This tier list ranks every mutation from S-Tier (legendary game-changers) to C-Tier (common duds), helping you instantly understand which mutations to celebrate and which to work around.
Tier List Methodology
Mutations are ranked based on four criteria:
- Multiplier Impact - How much the mutation changes an item's value
- Rarity - How commonly the mutation appears
- Stacking Potential - How well it combines with other mutations
- Practical Value - Overall profit contribution during normal gameplay
| Tier | Description | Multiplier Range | Frequency |
|---|---|---|---|
| S | Legendary, game-changing | 4x-50x | Very Rare to Rare |
| A | Powerful, highly valuable | 1.5x-35x | Uncommon to Epic |
| B | Decent, reliable earners | Medium multiplier | Uncommon to Epic |
| C | Common, marginal or negative | 0.8x-Varies | Common |
S-Tier Mutations (Legendary Game-Changers)
These mutations transform ordinary items into fortunes. Finding one is a landmark event.
| Mutation | Multiplier | Rarity | Stacking | Why S-Tier |
|---|---|---|---|---|
| Secret | 50x | Legendary | Overrides all | Highest multiplier, game-changing value |
| Gold | 4x | Rare | Stacks with Silver, Pure | Best ratio of rarity to value |
| Diamond | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
| Chrome | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
| Hologram | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
| Corrupted | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
| Gem | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
| Ancient | High | Legendary | Overrides Gold+ | Legendary visual, premium value |
Why Secret is #1: The 50x multiplier is unmatched. Even on a low-value item, the Secret mutation produces significant profit. On a Vampire Dominus, it creates 250,000 cash of value.
Why Gold is S-Tier despite being only Rare: Gold's 4x multiplier combined with its relatively high find rate (8% in Shipyard) makes it the most practically profitable mutation in the game. Volume of Gold finds produces more total profit than rarer mutations.
A-Tier Mutations (Powerful and Valuable)
These mutations provide major value increases and are worth celebrating when found.
| Mutation | Multiplier | Rarity | Stacking | Why A-Tier |
|---|---|---|---|---|
| Void | 35x | Epic | Overrides Gold+ | Second-highest multiplier |
| Timeless | High | Epic | Stacks with Silver, Pure | High value with stacking potential |
| Pure | 1.5x | Uncommon | Stacks with Gold, Silver | Excellent stacking partner |
Why Void is A-Tier, not S-Tier: The 35x multiplier is incredible, but the ~2% find rate in the Shipyard makes it too rare for practical farming. Its override behavior (cannot stack with Gold or Silver) also limits its ceiling compared to Gold stacking combinations.
Why Pure is A-Tier despite being only 1.5x: Pure's stacking potential elevates it. Pure + Gold = 6x, Pure + Silver = 3x, Pure + Gold + Silver = 12x. These combinations produce more value than the individual multipliers suggest.
B-Tier Mutations (Decent and Reliable)
These mutations provide moderate value increases. They are nice to find but not game-changing.
| Mutation | Multiplier | Rarity | Stacking | Why B-Tier |
|---|---|---|---|---|
| Silver | 2x | Uncommon | Stacks with Gold, Pure | Reliable doubler, good stacking |
| Rainbow | TBD | Epic | Under investigation | Unknown multiplier limits ranking |
| Antique | Medium | Uncommon | Stacks with some | Moderate value, limited data |
Why Silver is B-Tier: The 2x doubler is useful, especially on A-Tier and S-Tier items, but it does not provide the dramatic value increase of Gold or above. Silver is common enough to find regularly but not impactful enough to rank higher.
Why Rainbow is B-Tier: Despite being Epic rarity, the Rainbow mutation's multiplier is still being determined by the community. Without confirmed value data, it ranks conservatively in B-Tier.
C-Tier Mutations (Common and Marginal)
These mutations provide little or negative value impact.
| Mutation | Multiplier | Rarity | Stacking | Why C-Tier |
|---|---|---|---|---|
| Dirty | 0.8x | Common | Reduces any stack | Only value-reducing mutation |
| Tiny | Varies | Common | Stacks with most | Minimal value impact |
| Black | Varies | Common | Stacks with most | Minimal value impact |
| Cobwebbed | Varies | Common | Stacks with most | Minimal value impact |
Why Dirty is C-Tier: The 0.8x multiplier reduces item value by 20%. While a Dirty item can still be profitable (a Dirty Gold item is 3.2x), the Dirty mutation actively works against your profit. It is the only mutation that consistently reduces value.
Complete Mutation Value Comparison
This table shows the practical value of each mutation on a 1,000-cash base item:
| Mutation | Multiplier | Item Value | Stacked with Gold (4x) | Stacked with Silver (2x) |
|---|---|---|---|---|
| Secret | 50x | 50,000 | Override: 50,000 | Override: 50,000 |
| Void | 35x | 35,000 | Override: 35,000 | Override: 35,000 |
| Gold | 4x | 4,000 | - | 8,000 |
| Silver | 2x | 2,000 | 8,000 | - |
| Pure | 1.5x | 1,500 | 6,000 | 3,000 |
| Dirty | 0.8x | 800 | 3,200 | 1,600 |
Mutation Value per Hour by Area
This table estimates the total mutation value you earn per hour of active play in each area:
| Area | Gold Value/hr | Silver Value/hr | Void Value/hr | Secret Value/hr | Total Mutation Value/hr |
|---|---|---|---|---|---|
| Junk Yard | 80 | 100 | 0 | 0 | ~180 |
| Back Alley | 1,200 | 1,000 | 200 | 0 | ~2,400 |
| Farmyard | 4,000 | 2,000 | 2,000 | 200 | ~8,200 |
| Shipyard | 12,000 | 4,000 | 14,000 | 1,500 | ~31,500 |
These estimates assume approximately 30 items opened per hour in the Junk Yard, 40 in the Back Alley, 35 in the Farmyard, and 25 in the Shipyard (due to longer auction times for higher-tier containers).
Best Mutation Combinations Ranked
| Rank | Combination | Multiplier | Probability | Best Item Example | Combined Value |

| 1 | Gold + Silver + Pure | 12x | Very Rare | Camping Backpack | 24,000 |
| 2 | Gold + Silver | 8x | Rare | Vintage Camera | 12,000 |
| 3 | Gold + Pure | 6x | Uncommon | Gold Watch | 6,000 |
| 4 | Silver + Pure | 3x | Uncommon | Portable Speaker | 1,500 |
| 5 | Gold alone | 4x | Rare | Power Drill | 3,600 |
| 6 | Silver alone | 2x | Uncommon | Cookware Set | 800 |

Mutation Impact on Bidding
Use this table to adjust your maximum bid based on the area's mutation potential:
| Area | Adjust Max Bid Up By | Reason |
|---|---|---|
| Junk Yard | +2-5% | Low mutation rates, mostly Dirty |
| Back Alley | +6-12% | Gold mutations possible |
| Farmyard | +13-25% | Gold and stacking possible |
| Shipyard | +25-50% | All mutations possible including Secret |
Frequently Asked Questions
Which mutation should I hope for most? The Gold mutation (4x) is the best practical mutation to hope for because it combines high value with reasonable find rates. Secret (50x) and Void (35x) are more valuable per item but too rare to expect regularly.
Is the Dirty mutation ever useful? A Dirty-mutated item is still worth 80% of its base value. On high-value items, this is still meaningful. A Dirty Vampire Dominus sells for 4,000 cash, which is more than most non-mutated items.
How do I increase my chances of finding S-Tier mutations? Play in the Shipyard and bid on Diamond Safe containers. These have the highest mutation rates in Storage Hunters: Open World. Also, use gamepasses to increase your efficiency and open more containers per hour. Visit the official Roblox page to start mutation hunting.
What is the best mutation combination in the game? Gold + Silver + Pure at 12x is the highest achievable combination through stacking. However, Secret at 50x overrides all combinations and is the single highest multiplier. See our All Mutations Explained Guide for full details.
