But Harry learns (from Luccio?) how to FOCUS his fire into a laser like beam.
He does see Luccio do it in Dead Beat and internal monologues about how there's a big difference between him and her. He does get closer to that level of precision with his blasting rod, where she didn't appear to use a focus, but Harry was already getting more focus and control of his fuego spell. I wouldn't say he learned it from Luccio. I'd just say Luccio is a bench mark for what a wizard can accomplish after a lifetime as a combat specialist.
I don't think escalation of power is necessarily inevitable in serial fiction broadly or even serial fantasy fiction specifically. I do think it's almost necessarily inherent in the framing of the idea of the Dresden Files as Jim has talked about how he broadly conceived the idea. He's said things like it's about the young hot heads who haven't earned respect yet, he wanted a wizard who threw fireballs (I'm assuming that's a direct DnD reference), etc.
To be fair I think the term "Power Creep" is usually taken to mean how characters slowly become to powerfull for the obstacles they are facing. Like in DnD at lvl 5 the world is full of deadly threats, but at lvl 15 a good party can really steamroll a lot of things. Jim then states that he is not going to have this problem in Dresden Files because he has planned out the books till the end. In this way Dresdens power will never creep too high relative to the things he is fighting, i.e. there will be no power creep.
I agree, but I really like the thread so I just took the thread to mean Power Increase, which I think was Bad Alias intent.
Yeah. That was my understanding of the term from general usage as well. A good example is in collectible card games where the cards slowly get better and better so that cards from early releases become useless garbage which undermines the supposed backwards compatibility of earlier releases. TV Tropes says:
This trope is the Gameplay Mechanics counterpart to So Last Season, Overshadowed by Awesome, Sequel Escalation and Serial Escalation, which refers to narrative or thematic elements.
So power creep isn't really applicable because 1) it's not a game, and 2) Jim does it too well for the pejorative connotation of power creep to be fitting, but it's what Jim says, so I went with it.
One thing I like related to power creep is the realization that comes from meeting something that used to be a threat, but is not (much of a threat) anymore. Like in a DnD game where we early in the story had a boss fight with a troll and somewhat later had to conquer a small castle manned by lots and lots of trolls. That made the progression of our characters very clear. I hope we will see that in Peace Talks, e.g. Dresden punching an Octokong in the face.
One thing I like about how Jim handles power escalation, is that Harry, who was always way more powerful than "tiny fairies," to quote Bob, is still vulnerable to them after getting so much more powerful. And it's really enjoyable because it's not like Jim is just nerfing Harry to make them still a threat. Tiny fairies killed Aurora in book 4. Harry wouldn't have to worry much about a pixie, but a swarm is another matter entirely.
Another thing that I enjoy is that Jim explains why Harry doesn't just smash opponents he probably should be able to. The tiny fairies in CD were too close to the Za Guard and Harry just couldn't bring himself to immolating them anyway. In SG, he probably could have torn through the Octokongs, but he was surrounded by potential innocent victims.
