Coffee

Pathologic 2=

Coffee is a ration in Pathologic 2. It can be bought from groceries and the Broken Heart, or acquired via trading from Goose NPCs (who always carry 2 Coffees). When consumed by the player, Coffee reduces exhaustion by 20%, but also reduces health by 10% and increases hunger by 5%.

Besides Coffee, Lemons are the only other food item that reduces exhaustion, however Lemons reduce exhaustion by just 10% (but do not have any other stat modifiers).

"Has a strong effect on the heart and blood vessels which this environment makes even more harmful. On the other hand, coffee decreases fatigue, making it essential during emergencies."
