Desert Sun / Heart o Winter mechanics and question

[Norfleet]

DS/HoW causes your heat and cold to bleed out to neighboring provinces. I'm not sure exactly what the formula to determine this temperature-bleed is, but if you're using these domains, in conjunction with a level 3 scale, it'll greatly stabilize the temperature in your OWN dominion through cross-bleeding as your temperature scales bleed into each other. Without it, temperature scale tends to be somewhat unstable, even at mid to high dominion, and it'll be difficult to consistently enforce heat/cold-3. If your race does not have a strong temperature preference wired into it, there's no need for this dominion option: However, it pays off particularly well for races like Caelum and Abysia, which benefit massively from extreme temperature scale, and cause many opponents to suffer greatly.
