Heavy-metal poisoning

Heavy-metal poisoning uses HEAVYMETAL and has three severity phases.

Effects in DayZ

Depending on phase and agent load, effects include water loss, tremor, pain, impaired hearing and severe health effects.

Chelating tablets activate a 300-second chelation modifier. Heavy-metal agents have zero resistance to chelation and do not grow during that attack.

The Purify Water recipe explicitly retains heavy metal. Ordinary purification tablets are not equivalent to chelation.
