Sacrifices: 300 health - +1 fury
600 health - +2 furies
1200 health - +3 furies +1 minotaur
2400 health - +4 furies +1 minotaur
4800 health - +4 furies +2 minotaurs
You need to sacrifice for the exact number of health points at once; adding gradually does not work.
2 Raja Rakshasa: If you start with a level 1 town, there will be no raiders in the first week (just like no vampires, druids, or succubi, but for some unknown reason, mages and griffins have a privilege :( ). But more often you start with a tavern and a fort, then you make it in time:)
There are many useful abilities; it's just better not to engage significant shooters with small forces without tactics, as you will suffer serious losses of furies.
