stoffe

Hello, I'm working on a power idea, and I was wondering, is it possible to edit the following (just so I don't propose anything impossible):

What powers are acquired when a prestige class is chosen (for example, in TSL, I'm thinking of three rage powers for the first fifteen levels, then the fury buff; If marauder is selected, all three rage powers are added).

Is it possible to have a power requisite setup like this;

push -> whirldwind -> wave

blast (req push) -> imp blast -> mas blast

or

shock -> lightning -> storm

sith lightning (req lightning) -> master sith lightning
