Mutations are one of the most effective ways to boost your income in Steal a Brainrot. They enhance the base earning rate of your units and can turn even common brainrots into strong money generators.
Some offer multipliers as high as x10, making them a key factor in progressing faster. This guide covers every mutation in the game, its effects, and the steps you can take to get them efficiently.
All Mutations in Steal a Brainrot

Mutations increase the income rate of your brainrots and slightly change their appearance. Each unit generates money based on its base rate per second, and applying a mutation multiplies this rate. Below is a list of all available mutations and their effects:
- Gold: Increases income by x1.25
- Diamond: Increases income by x1.50
- Lava: Increases income by x6
- Rainbow: Increases income by x10
These multipliers make mutations essential for faster progression, especially when you are trying to earn millions for rare brainrots.
Some older mutations are no longer available in the current version of the game. They include Bloodrot, Celestial, and Candy. You can only find these on servers with admins who can spawn units carrying them.
How To Get Mutations
There are only two ways of obtaining mutated brainrots: buying them from other players or stealing them during gameplay. Mutations spawn randomly, and rare ones such as Lava and Rainbow appear far less frequently, making patience and timing crucial.

To improve your chances of getting mutated brainrots, focus on increasing server-wide Luck. Use every Luck booster available, play with friends to stack bonuses, and purchase the Server Lucky Boost gamepass to double the server’s Luck in exchange for Robux. After activating these boosts, stay alert for Secret or Mythic brainrots, as they are more likely to spawn with valuable mutations.
Securing a Lava or Rainbow mutation can multiply your income several times over, but to make the most of them, you need to build a strong base of units. Prioritize protecting your high-multiplier brainrots from other players and use your increased earnings to invest in rare units. Combining effective defense with strategic trading and active hunting during rare spawns ensures that your mutated brainrots generate the highest possible return.
