Sorry if this has been asked before, but searching the forums and checking the FAQs, I haven't seen the answer.
I have a multipower with 30 active point pool, no advantages to it, with a total -3 in limitations on it, so 7 points. There are 4 fixed slots under this, each using the full 30 active points.
The limit I can raise my pool is to 50 active points in the campaign.
So, if I raise my pool to 50 points, do I have to spend exp to raise each slot, since the cost of each slot would still round down to 1 each? Or should I pay the exp per slot to bring it up to the 50 points?
