Mutations are the profit engine of Storage Hunters Open World. Every item you win at auction can spawn with a mutation that multiplies its resale value — from the punishing Dirty at 0.8x to the legendary Void at 35x. Understanding mutation tiers separates players who build storage empires from those who overbid on junk lockers.
How Mutations Work
When you win a storage locker and extract items, each piece may carry a visible mutation effect. The mutation multiplier applies to the item's base value before condition, grade, and auction fees. A $1,000 base item with Gold mutation (4x) grosses $4,000 before other modifiers. This is why veteran bidders watch for mutation glow effects during locker previews and adjust their maximum bid accordingly.
Use our mutation value calculator to model any combination before hauling. Cross-reference rankings on the mutation tier list when deciding whether to outbid rivals on a glowing locker.

Top-Tier Mutations
Void (35x) is the undisputed profit ceiling. Finding Void on a high base-value item can single-handedly fund your next shop upgrade. Hologram (15x), Rainbow (18x), and Timeless (20x) form the elite band where auction competition intensifies. Gold (4x) and Diamond (8x) are more common but still drive solid returns on mid-tier finds.
Mutations to Avoid Overbidding On
Dirty (0.8x) and Rusty (0.9x) reduce sale value below base price. A locker full of Dirty items can turn a winning bid into a net loss after auction fees and transport time. Always factor mutation penalties into your bid cap using the calculator before the gavel falls.
