Reaper and a question

[Behcio]

Hi there.

I've been wondering - is it normal that when Reaper levels up and I get the chance to improve Soul Drain (right now it's 30% for 20 rage - I got the "lower cost" on the way) it'll make that skill kill 40% for !45! rage? I mean, is the lower cost vanishing here or something? I'd love to improve that skill but not as such high cost. Maybe there's a way to bypass that problem?

And another question isn't really related to spirits but I didn't want to make an another thread.
I saw in the patch notes, that children are chosen randomly now after reloading the game. Does the same apply to the slot it takes? I want to know if I can just try [fighting the 10th battle -> checking the child out -> loading if not satisfied with the kid's bonus and/or slot -> repeat] approach. Or... I can resort to cheating but I'd rather not to
