Of course, Taylor would first need to know that sorcery is a thing that she can learn. And then she'd have to know that summoning was an option. And then she'd have to figure out the kinds of things she could summon. So clearly there's a bunch of hurdles that Taylor needs to overcome because last time I checked, Earth Bet doesn't have any sorcery books for Taylor to get her grubby, min/maxing hands on.
Which is unfortunate, because summoning would be right up Taylor's alley since it works off a couple of her major traits/personality aspects:
- Command/support. Beyond summoning an army, you also get access to a lot of nifty support demons like Perroneles, Sesseljae, etc.
- Utility. Summoning lets you approach problems from unconventional angles with proper demon selection.
- Min/maxing. There's a lot of power that you can squeeze out of even basic Terrestrial level Demon of the First Circle.
- PR. Proper demon selection allows to project a carefully crafted image. Positive, "Good" PR: summon harpists, dancers, Agatae. Fear-based PR: summon Tomascu, Luminata.
As an example, think about how fights against Leviathan might go differently if the PRT had something as simple as access to a couple squadrons of Agatae. It doesn't trivialize the fight (which is good, from a narrative standpoint), but it makes it much more likely that the PRT will walk out of the fight with significantly fewer losses thanks to the incredible mobility boost.
And since Agatae are supernaturally beautiful creatures, they also serve a great PR function. Taylor, of course, is going to need a better cape name. Lightshow is a bit...underwhelming.
