Regular mutations are rare rolls applied when you obtain Brainrots. Event mutations can use separate event mechanics: the 45× Nerd Mutation is crafted through the Nerd Machine rather than randomly dropped.
| Mutation | Multiplier | Drop Rate |
|---|---|---|
| Gold | 1.5× | 1 in 10 |
| Diamond | 2× | 1 in 25 |
| Plasma | 4× | 1 in 33 |
| Molten | 6× | 1 in 125 |
| Radioactive | 8× | 1 in 333 |
| Shadow | 12× | 1 in 2,000 |
| Electrified | 16× | 1 in 5,000 |
| Rainbow | 40× | 1 in 20,000 |
| Astral | 50× | 1 in 50,000 |
Nerd is guaranteed through the Nerd Machine and does not use a random drop rate.
The quality of your drop depends entirely on how far you kick the block.
Multiple luck sources stack multiplicatively:
This is the most important part: you only get the item if you survive.
For regular mutations, max your power, survive the Tsunami, and stack Luck boosts. For Nerd, save matching Plasma-or-better Brainrots and 350 Score, then use the Nerd Machine recipe.
