whats the rarest mutation inopen acution roblox

In Storage Hunters: Open World on Roblox, the rarest mutation appears to be Secret based on the current guides I found, and it also has the highest listed value multiplier at 50x. Another guide says Void is extremely rare too, but it places Secret above it in value and rarity discussion.

What that means

• Secret : currently described as the most valuable mutation, with a 50x multiplier.

• Void : also listed among the extremely rare mutations, with a 35x multiplier.

• Rainbow : mentioned as even higher in value in one guide, but that source also says Black is currently unobtainable, so it may not be a practical in-game target right now.

Quick read

If you mean the Roblox auction game Storage Hunters: Open World , the safest answer is Secret. If you meant a different Roblox game with “open auction” in the title, tell me the exact game name and I’ll narrow it down.
