So, there will be character advancement in the Dresden RPG and Player characters must have positive refresh according to what's been revealed so far. Changeling characters loose refresh when they take additional powers, and get closer to becoming full out fae. Wizards can become more powerful over time, which might include buying additional powers, and losing refresh.
So does character advancement include increasing a character's refresh at certain points? If so, could a changeling become fae, or at least buy more fae powers over time without becoming an NPC. If not, does that imply that certain levels of Wizarding power are locked away for NPCs only(i.e. Merlin is always an NPC, so no PC will ever stop the entire Red Court attack with a single ward)?
It would make sense to me that advancement would increase refresh ... lycanthropes could have better control of their rage(more refresh means it's cheaper to spend fate points avoiding compels), Werewolves could buy a more powerful wolf form(the previews from Turn Coat suggest Billy's gotten more powerful then he used to be). Wizards could buy additional powers, or have more fate points to power up the powers they already have.
