Some quick questions

[Fate]

I still do not have the full game ( ) but me and my friend play the demo a good deal. I have done some tests on the game, and figured some stuff out, and read alot of the forums, but some questions I don't seem to be able to get answered.

Firstly, I noticed that death and nature give fear and suply bonuses, respectively. I was just wondering if these are the only two paths that do this, or if others do too (besides bless effects).

Second, I have seen cold + heat and untis frozen/on fire but I don't know what it does. Does anyone know?

Finally, I have always wondered how morale works. Does it effect one squad if another retreats? Do non-retreating units retreat if their squad members do? Does anyone know the equations for morale loss?

Any answers would be welcome, thank you very much.
