Wha? No, E10 is the maximum, even among Primordials. Even Ebon Dragon explicitly has Essence 10.
Furthermore, Essence 10 Solars are bound to surpass Primordials:
... oh god, I'd actually forgotten that RotSE statted out a Primordial.
Urgh. Let me just go and cry in a corner for a while.
To explain... what a lot of people have been saying about how the later period of 2e mechanised certain things in ways that clashed very badly with previous elements of the line, and gave prominence to areas of the game that until that point had been very deliberately avoided? That writeup - that whole book, really, but especially that writeup - is a good example. We have more
Yozis written up and fully mechanically statted out than we do
Third Circle Demons. You know; the endbosses that you're actually meant to interact with. Yozis are the
video game level. All the way back to 1e, you weren't really meant to be able to get into a punching match with Malfeas, because a) by that point the system has broken so far beyond belief that there's no point in having it anymore, and b) you fight Malfeas by
fighting his Third Circles culminating in an endboss fight with Ligier; that is what Third Circles are for.
1. Get Essence 7+ and Lore 7+ and Learn Shinmaic Calibration.
argh argh argh that charm argh
Yeah, it's not really a secret that basically any Charm with an Essence prereq of 6+ is terrible. Like, this isn't just me talking; it's a widely held opinion. Dreams of the First Age was
shit for elder Charms; it's where fucking
Zeal came from. That one in particular takes a good long look at Sorcery, and everything thematic about what Sorcery is meant to be able to do and what parts of the setting should be accomplishable by it, and how Charms are mostly your personal scale magic and for huge flashy wide-scope effects you become a sorcerer because it plays at the scale where the smallest attack spell takes out entire battalions, and then it goes "HAHAHA NOPE LOL" and boots it out of the way and makes something that should be a massive Adamant Working taking dozens of sorcerers conducting massive rituals at all five Elemental Poles into something that a single Exalt can casually whip off on their own.
