[@KillamriX88] Ooh, sounds interesting >:D. I've said before that you can grab new powers when you feel like you should, so if you think your character's developed enough through the adventure I won't say no to a new power.

In that regard, after the Apartment you'll all be able to get a new minor power if you want, or save the 'exp' so to speak for a major one later on. There'll also be a handy timeskip to fasciliate this so you can say you trained it or something along those lines.
