Some Questions

[Hadrian_II]

I have some questions.

1. When the Pebble Skin Suit changes a mage into a troll, what happens then, does he just change his unit type into a troll, or does he also loose some magic?

2. When i understand the Stonesword correctly its able to kill its wielder. But stonebeeings are immune to it, so which chassis should i use for a stonesword thug/SC?

3. How is the path distribution of Kitsunes (Jomon national summun) i got one with N4S2 and others with just N3?1 so i suspect that he has at least 2 50% randoms, does someone know how the real thing works?

4. Melancholia has a chance that enemy soldiers desert, is this chance high enough that it would make sense to spam melancholia on enemy armies?

thanks in advance
