If you're an empowerment class and you haven't met your immortal how many character hours and real time days do you wait before concluding that there's something wrong with your character concept and that it's not going to work out? What if you have an IC hint from another PC that there could be an issue (but not necessarily a highly reliable hint)?

Does the not-strictly-necessary nature of empowerment mean that the RP-quality bar for empowerment is pretty high? How do you know if your RP isn't going to be good enough?
