Disease Resistance

Disease resistance is a derived statistic in the SPECIAL character system.

Each consumable or attack from a creature has a percent chance of causing a disease. Disease Resistance decreases the chance of a player character contracting a disease.

Disease resistance can be increased by being Well Fed and Well Hydrated, which require maintaining a player character's food and water needs. Each effect increases disease resistance by 25%. The perks Iron Stomach and Thirst Quencher will also increase disease resistance, especially for player characters risking disease by eating and drinking to be well fed and hydrated. The Vaccinated perk increases resistance of diseases specifically from attacking creatures.
