I don't think that a chargen Dawn Caste being able to reliably kill elder Exalts is like, desirable, especially not if they don't even have to be a bizarre optimisation monster. That they are arguably capable of doing this is a combination of certain Solar abilities being badly overtuned and a lot of QCs for Lunar elders etc. being really conservatively written. Like, I think that Solar should definitely be one of the more dangerous people alive, but immediately trying to fight a millennia old Full Moon or Chosen of Battles shouldn't be a sure thing either that you feel confident about winning. That's not particularly good for the setting
I, on the other hand, think that it's actually very fine and good for the game and the setting if the category of "elder Exalt" has enough flex in it that you can kill some of them straight out of chargen. Anys Syn or Lilith? Probably not. Ma-Ha-Suchi? Maybe, on a lucky day - he's mostly an "army guy", not a "duels guy", in my mind. Ragara or Cathak Cainan? Now
that's a spicy question - I'm leaning towards "yes, but you shouldn't feel
too confident about it".
"How do I challenge my Solar PCs when the Dawn wrecks anything balanced for the group and if I balance for the Dawn the other characters would explode" is a legitimately serious recurring problem for new STs, and the stock "you don't" response at some point just feels like more of a cope than anything.
I get the concept that "mechanical challenge is an important thing a lot of people want to have in their game", but like--
- having a huge, freeform system where you can be multiple flavors of "sword demigod" or "socialite demigod" and have dozens of special magic powers you can buy for your shtick is clearly desirable
- having those individual special magic powers be actually impactful enough that the player who has significantly more of them has a commensurate edge is obviously also desirable
- if the socialite demigod and the larceny demigod and the investigation demigod want to be as good at their shtick as the sword demigod is at swording, then clearly they should be buying 12 Charms in those things instead of putting them into swording
- this means that right out of chargen, the sword demigod will have a 10-Charm edge and that edge will
keep growing as the game progresses because the Dawn's player will mostly keep buying combat Charms, and everybody else will buy Charms for whatever their shtick is
I don't think it's possible to design a game in such a way where "how do I challenge my Solar PCs with my cool boss encounter when one of my PCs has
5-10 times as much investment in combat than anyone else in the group" has a good answer
and having 5-10 times as many combat Charms as another player is, like, a value-add that feels commensurate with the investment.
The issue is not helped by the fact that for some groups, "low combat investment" will mean "I have Dex 4, Melee 3 and maybe a 3-dot daiklave if I'm feeling spicy", and for other groups, it means "I have Dex 5, Melee 5, a daiklave and a specialty in wielding that daiklave, like everyone else, but other than that, I'm just grabbing the standard package of ES, DSD, FSS, TAP, and an Ox-Body, as you do when you're feeling casual". Designing encounters in such a way that the Dawn can sweat a little but other PCs won't immediately explode is far easier for the latter than the former!
