Steal a Brainrot Mutations List - Complete Guide 2026
Mutations are the rarest and most valuable modifiers in Steal a Brainrot. A single good mutation can transform a common brainrot into one of your most valuable assets. This guide covers everything about mutations.
What Are Mutations?
Mutations are rare visual and statistical modifiers that can appear on brainrots. Unlike traits, mutations:
- Are much rarer (0.01% to 5% chance)
- Often provide larger multipliers (2x to 10x)
- Include visual effects (glows, particles, colors)
- Some are limited-time or event-exclusive

|---|---|---|---|
| Common | 5% | 1.25x - 1.5x | Subtle glow |
| Uncommon | 2% | 1.5x - 2x | Colored glow |
| Rare | 0.5% | 2x - 3x | Particle effects |
| Epic | 0.1% | 3x - 5x | Major visual changes |

Trading

Mutation Stacking
If a brainrot has both a trait AND a mutation:
Total Value = Base × Trait Multi × Mutation Multi
Example:
- Base value: 100
- Mighty trait: 2x
- Golden mutation: 3x
- Final value: 100 × 2 × 3 = 600
This stacking is why brainrots with both good traits AND mutations are extremely valuable.
