Hollow

Hollow: Permanent for the run: removes trauma and depression but blocks speech, trading and crafting until INT is rebuilt.

Use, trade-offs and mechanics

Hollow is the state produced by a mindwipe, not a normal unhappy-mood tier. It can follow drinking Mindwipe, consuming more than forty milliliters of braingrow at once, or using braingrow or a neural booster while RNRS is active. The community reference describes it as permanent for the run.

The immediate mindwipe sequence includes a delay, ragdolling, pain, hearing effects and forced sleep. It then raises living brain health, clears stroke, resets intelligence and resets recipes to their not-yet-crafted state. A player choosing it for emergency recovery is consequently accepting changes to cognition and progression, rather than taking a stronger version of an ordinary brain medicine.

Hollow removes trauma over time and moves both positive and negative mood toward zero. It also makes the display grayscale and prevents speech. Brain integrity above ninety-six is gradually reduced, creating a practical cap. The absence of depression after the change does not mean that all other health problems have been cured.

Reset intelligence affects fluid identification, crafting access and trading. Blueprints and later intelligence gains can restore some practical abilities, but they do not remove Hollow itself. Previously identified supplies may still be useful if the player remembers what they contain; the game no longer provides the same recognition. This distinction explains why the status can keep a run alive while also dismantling its previous crafting plan. The Mindwipe and RNRS article supplies the mechanics; the Moodles page is a second page of the same community source, not independent verification.
