Frostbite

Each space can be affected by Frostbite.

Frostbite occurs in Winter on all Grass, Dirt, Desert, Rubble, Soil and Crops tiles if at least 20% of the map is covered by Chaos.

In the Decay phase, ground units that remain in Frostbite become Chilled. Chilled units cannot attack or use abilities until they move at least one tile. This effect wears off at the next Decay phase.
