here's all i found talked about them in the ask the devs thread

>While Abyssals and Solars have much in common, theirs is not a perfect symmetry. The Abyssal Exalted are masters of necromancy—it says so in their prestige spread!—and we need to be able to give them something unique and powerful in necromancy without outdoing the Solars completely. Weakening Abyssal's proficiency with Evocations creates room to give them more power in other places.
so are abyssals not stolen exaltations anymore? or is it more complicated than that?

And, for the bonus round... Necrotech. Is it best to treat Craft(Necrotech) as, say, Craft(Artifacts) [or First Age Artifice, but less difficult to start learning], and then allow characters to build, say, siege engine-esque creatures as part of superior projects?
>Necrotech isn't going to exist as a discrete >category any more. Undead siege engines are >likely to be the result of necromancy in Ex3, >rather than Craft.
Will there still be something like resonance that forces the abyssal to kill?
>My current plan is to call it Limit rather than >Resonance, but otherwise have it largely >resemble their Dark Fate in First Edition.
Do people still have to promise to murder the entire world to become a Deathknight?
>There are still Abyssal Exaltations unclaimed >by any Deathlord, as described in Ink >Monkeys, so no.
>Also, even if you are Exalted by a Deathlord, >you can cross your fingers. It's not like most of >them actually plan to murder the entire world; I >bet they'd be willing to overlook it.
