Dark Craving

The Dark Craving is an addiction in Fallout 4. It is a negative status effect inflicted upon the Sole Survivor while in survival mode.

Effects
The effect is gained when the Sole Survivor feeds upon a corpse to satiate their hunger. Food will no longer sate hunger; the player character can only commit cannibalism to fulfill hunger requirements and will go straight from being satisfied to ravenous instead of the intermediate statuses (peckish, etc). The Sole Survivor will stay satisfied for 12 game hours before needing to commit cannibalism again (one normally needs to eat every 6 game hours). One corpse will take the Sole Survivor from ravenous to well-fed. This perk seems to ignore the Parasites disease. The game treats this as an addiction, which can be cured by any doctor NPC for 75 caps. This will appear as a dialog option. Addictol or Refreshing beverage will not cure the addiction, but a radscorpion egg omelette will.

Behind the scenes

 * This side effect may be a reference to the Wendigo legend of the native americans, where people who commit cannabilism will be possessed by a malevolent spirit and cursed to perpetually crave only human flesh and would be the only thing to satiate them, though only briefly.
