Bloodrot
Steal a Brainrot mutation × 2.
Bloodrot — In-Depth Analysis
Bloodrot lands a x2 income multiplier on any brainrot it touches, doubling the cash per second that character generates on your base. That puts it squarely in the mid-range tier: notably stronger than the common Gold (x1.25) and Diamond (x1.5) mutations you see constantly, but a good distance below the elite Phantom (x12), Cyber (x11), and Disco (x11) rolls that define true top-tier value. It is still a meaningful upgrade — a doubled earner pulls away from an unmodified copy fast over a long session.
Mutations are applied through the Mutation Spinner, which you can run on any brainrot you own, or they can emerge from a Gold Lucky Block drop. The higher the multiplier on a mutation, the rarer the roll, so Bloodrot sits comfortably above the most common outcomes without reaching the near-impossible odds of a Phantom.
Beyond the income boost, Bloodrot visibly recolors the affected brainrot and stacks on top of any trait multiplier already earned on Red Carpet events — making the final figure higher than either bonus alone. A brainrot carrying both a strong trait and Bloodrot becomes a premium trade piece, and a high-value target for thieves, so keep it guarded on your base.
