✨ Steal a Brainrot Mutations
Every mutation, its income multiplier, how to get it, and what it means for trading. Mutations are the base multiplier on any brainrot — only one can be active at a time.
📖 How Mutations Work
One at a time
Each brainrot can only have one mutation active. You cannot stack two mutations on the same brainrot.
Base multiplier
The mutation multiplier is the foundation. Traits then stack on top using the formula: Total = Mutation + Trait1 + Trait2 − (N−1).
Collection bonus
Collecting all brainrots of the same mutation type grants +0.5x Base Multi and unlocks a matching Base for your island.
Trade value
Higher mutation multiplier = higher trade value. Event mutations are rarer and worth significantly more than common ones.
🟢 Common Mutations — Always Available
These mutations can appear on brainrots during normal gameplay at any time. No special event needed.
No multiplier bonus. The base state of every brainrot. Low trade value but needed for the Default collection bonus.
🎯 Always — base state
A subtle golden shimmer on the brainrot. 25% income boost. Common enough to find regularly, decent for early trading.

🔥 Event Mutations — Limited Time
Event mutations only appear during specific in-game events or when spawned by admins. They are rarer and generally worth more in trades.

📊 Mutation Tier List (Best for Trading)
📐 Multiplier Formula
Total = Mutation + Trait₁ + Trait₂ + ... − (N − 1)
Where N = total number of multipliers (1 mutation + number of traits)
Example 1 — Simple:
Gold (1.25x) + Taco trait (3x)
= 1.25 + 3 − 1 = 3.25x
Example 2 — Multi-trait:
Lava (6x) + Galactic (4x) + Fireworks (6x)
= 6 + 4 + 6 − 2 = 14x
Example 3 — Best combo:
Rainbow (10x) + Strawberry trait (8x)
= 10 + 8 − 1 = 17x
