While inside the region, the player character gradually loses '''Body Heat''' over time. Losing all of one's Body Heat causes ''Frostbite'' and eventually ''Hypothermia''. Frostbite reduces direct damage dealt by 20%. If frostbitten for too long, Hypothermia sets in, which deals Health damage continuously, disables health and power regeneration, and reduces movement speed by 50%. Both effects can be healed by taking refuge in a warm area (for example near a lit ''Smouldering Fire ''' in Kur, or near a '''Glowy Yellow Crystal ''' outcropping in Gazluk). Left untreated, hypothermia will eventually kill you.

Body Heat depletes much more rapidly while '''underwater'''.
