Steal a Brainrot is a Roblox game where you collect and optimize Brainrots to generate cash. Two systems directly affect how much money your Brainrots produce, Traits and Mutations.
Mutations are special variants that change your Brainrot’s appearance, including color and aura effects. Each mutation provides a multiplier boost to cash generation per second, with some offering better earning potential than others.
Traits are cosmetic modifiers that stack on top of your Brainrot’s existing mutation. They provide additional multipliers to your cash per second, letting you boost earnings beyond what the base mutation offers. In this article, we’ll break down every trait and mutation available in-game, what they do, and how to obtain them.
Complete List of All Mutations
The game currently features 8 different mutations that apply to any Brainrot. Each mutation changes your Brainrot’s appearance and provides a different cash multiplier boost. Players who buy Brainrots specifically look for mutated ones since they generate significantly more cash per second than non-mutated versions.
Here’s the complete list:
| Mutation | How to Obtain | Multiplier |
| Gold | Spawns randomly on brainrots | x1.25 |
| Diamond | Spawns randomly on brainrots | x1.5 |
| Rainbow | Spawns randomly on brainrots | x10 |
| Bloodrot | Could only be obtained from the Bloodmoon Event | x2 |
| Candy | Could only be obtained from the Candy Aurora Event | x4 |
| Lava | Could only be obtained from the Molten Event | x6 |
| Galaxy | Can only be obtained from the Space Event | x7 |
| Yin and Yang | Can only be obtained from the Yin and Yang event | x7.5 |
Three mutations spawn randomly on any Brainrot you encounter: Gold, Diamond, and Rainbow. Rainbow offers the highest multiplier at x10, making it the most valuable random mutation you can find.
The remaining five mutations are event-exclusive and can only be obtained during their specific events. If you missed an event like Bloodmoon or Candy Aurora, you won’t be able to get those mutations until the event returns.
Complete List of All Traits
The game offers 15 different traits that can stack with your Brainrot’s mutation for additional cash generation. Each trait has its own obtain method and multiplier boost.
