SURVIVOR HEALTH · DAYZ
Toxicity
The toxicity condition uses the survivor toxicity stat and can trigger vomiting.
Effects in DayZ
The toxicity modifier reduces the toxicity stat over time and checks for vomiting above its threshold of 70.
What helps
Stop adding toxicity. The modifier implements automatic toxicity cleanup over time.
Important distinctions
The toxicity stat is distinct from the FOOD_POISON and CHEMICAL_POISON agent pools. A drug acting on one agent does not automatically remove the toxicity stat.
