Do you pay for the attribute increases on top of that? It seems like that would make sense if they have no cost but it's not entirely clear.
Metatypes get their same bonuses. The main difference is that Attributes have an
exponentially increasing cost in karmagen. In other words, in build points, an ork starts out with a 4 in Body and you spend 10 BP for each point that you want to increase it. In karmagen, an ork starts out with a 4 in body, and then you have to pay 25 karma to increase it to 5, 30 more karma to increase it to 6, and so on. So things like an ork with a Body of 8 or an elf with a Charisma of 7 are more expensive. It's not like build points, where increasing an Attribute from 1 to 2 costs the same as increasing a troll's Strength from 8 to 9.
While I disagree with how karmagen was originally set up, with metatypes for free, this is the reason it
was that way - because metatypes such as trolls had to pay so much more for higher Body and Strength.
