[LDiCesare]

I cast it twice. Once, I got 1 chieftain, 5 warriors and about 15 regular unfrozens, which I found pitiful. On the second casting (other game), I got a chieftain, 5 warriors and 7 regulars, 2 mages (E2D1 and E2W2D2 if I recall well). The last mage is good, but the spell's still overly expensive and random in my opinion.
I haven't made any attempt to reproduce casting by season/mage/number of spells. I somehow doubt the number of castings has an effect, since these aren't unique, but I may be wrong.
