Braingrow

Braingrow: Only consumable that raises brain health; gives 20 minutes of rapid neuron regeneration sickness. In-game item, not medical advice.

Use, trade-offs and mechanics

Braingrow is an orally used brain-recovery fluid. Its twenty-milliliter reference gives ten brain-health points over one hundred seconds, reduces stroke during that period and adds sickness. Brain recovery is gradual rather than a single instant restoration, so removing whatever is still damaging the brain remains relevant while the effect runs.

The central restriction is rapid neuron regeneration sickness, usually shortened to RNRS. A normal use adds twenty minutes of this state. Taking more braingrow, or a neural booster, while RNRS is active triggers a mindwipe in the community mechanics. Consuming more than forty milliliters at once is another listed mindwipe trigger. Repeating an apparently helpful recovery item can therefore change the whole run rather than simply healing faster.

Mindwipe is not just another name for brain healing. It resets intelligence, changes crafting access and applies Hollow. The related pages describe those consequences separately. Check for RNRS before interpreting a second bottle as an ordinary follow-up dose.

The fluid is not craftable and is listed in braingrow bottles or mini-barrels. It is also an ingredient for neural boosters, making stock allocation relevant. Injection is not the useful recovery route: the entry lists sickness per injected milliliter without the oral brain-health package. Keeping the bottle name, fluid identity, current RNRS state and intended interaction visible helps distinguish recovery from an irreversible mindwipe decision.
