SURVIVOR HEALTH · DAYZ
Heatstroke
Heatstroke is a four-phase condition controlled by survivor thermal bias.
Effects in DayZ
Its phases can increase water and energy loss and cause hot symptoms, blurred vision, vomiting, fainting and health loss at severe levels.
What helps
Reduce thermal bias to leave the heatstroke activation ranges. Phase conditions are tied to thermal bias rather than an infectious agent.
Important distinctions
Antibiotic or charcoal modifier duration is not a cooling treatment.
