1 Year

Earned during the 1 Year Event, a seasonal celebration that briefly transforms the map with firework-like launchers lining the path, the 1 Year trait lands on brainrots at random while the event is active. Like all seasonal traits, it appeared for a limited window and cannot be obtained outside that event window — making any brainrot carrying it a product of timing as much as luck.

The x5.5 income multiplier is a meaningful mid-to-upper-tier boost. It sits well above the common x1.5–x2 range that barely moves the needle, and comfortably clears x3–x4 territory, though it stops short of the elite x9 Strawberry that tops the OG trait ladder. In practice, every brainrot this trait touches generates more than five times its base cash-per-second, which adds up fast on a well-stacked base.

Because traits are permanent and stack on top of any Mutation a brainrot already carries, a 1 Year brainrot with a strong mutation multiplier becomes a serious cash engine — and a serious theft target. Keep it deep on your base, away from easy reach, and treat it as a high-value trade piece if you ever want to move it.
