When using an area of effect attack the book states that you need only hit the hex. Does this apply to mental attacks as well or do you have to roll against the ECV of each person in the AOE?

I am building a character and want to give him the disadvantage " Can not spent experience points". The reason is that I have very carefully considered his background and based on his heredity he will, at some point in his career, suffer the classic "radiation accident" and significantly change. At that time all the experience points he has been saving will be spent on his new form. How many points would you give this disadvantage?
