Fire and temperature scales

[Edi]

No effect on flame weapons. Heat and cold scale affect units, not their equipment. Units with the fire power and cold power abilities are affected positively by their own scale and negatively by the opposite. National heat scale preferences can also affect at least some troops.

[Folket]

Wyatt Hebert is right. There is an indirect effect. Flaming weapons can turn people on fire and in heat that fire is likely to last longer.

Also, heat and chill auras are affected.
