I feel as if I need to be a single class Cipher to get the most out of the Ascendant subclass. Once I get to max focus and become ascendant, I start casting Disintegration on everyone which is the highest power level spell I have at the moment (I'm only level 16). By the time the ascendant effect wears off and my focus resets to zero, I feel as if the number of casts I can get off amount to the same as if I didn't have the free focus costs. So if I'm at 240 focus and I wasn't Ascendant, I can cast Disintegration 4 times before reaching 0 focus. This is about the same amount of casts I can get off before the ascended effect wears off. So what's the point? Of course, the spells do more damage while ascended, but I don't know if it's worth picking the subclass for just the increase in power level.
I wanna add that if I pick a single-class Ascendant, there's the matter of not generating DPS quick enough to attain the ascended state. Also, the higher level Cipher spells aren't that great tbh.
Maybe a multiclassed Ascendant really shines once it gets access to level 7 spells. Anyone got recommendations for good level 7 Cipher spells to cast while ascended?
