Demons: Chaos value and Power
First of all, I own the Finnish edition of Stormbringer. I guess it's somewhat similar to the 2nd or 3rd American edition: there's only summoning-related magic, and race & character class are determined randomly.
I have couple of questions about creating/summoning demons. First, what does the Chaos value (or whatever it is called in English) actually do? The cost of sacrifices needed to summon the demon? Secondly, how to determine demon's POW? Is it determined from the Chaos value? In the demon shopping list it says you can buy any other characteristics with a price of 3 Chaos value / 1d8 of that characteristic, but that Power is not solved in similar way. However, I haven't found any rules regarding the POW and how to actually determine it.
