It’s pretty safe to say that Sylvanas got a pretty big power spike in between Legion (and expansions before) and BfA, even from the BfA cinematic where she can turn into a mist that just instagibs fully armored soldiers
Probably most obvious is the fact that she can flat out fly now, which always bothered me after the Undercity cutscene
Now it’s shown on top of all of this, she can just hurl blasts of pure death, which we witnessed recently, and it’s serious magic, with no charge time, didn’t even seem to exhaust her at all, and even the best spellslingers (Jaina, Khadgar, Thalyssra) have to channel their spells or charge up for a good while
It’s to the point that other mages are like, “wut hunter casts chaos bolt lol how dis happen” and have no idea how to categorize the ‘magic’ used, and it’s to the point Sylvanas, known as an extremely skilled archer, hardly uses her bow anymore
I mean granted yeeting Instagib Bolts seems a bit more effective than a bow
I know the popular theory is that Sylvanas is using ‘death’ magic, but outside of it being deadly I’m not buying it: Death Knights have been using ‘death’ magic for ages, and can actually perform necromancy without the aid of a Val’kyr, our Mage Gals™ would have picked up on this if this was the case
I’m of the theory that whatever the Banshee Goddess is using, it transcends magic, or at least what we know of it: It may not even classify as magic because it seems to go far beyond what is possible with it which is why the Mage Gals™ have no idea what it is
I’m sure more info will be released later but for now, I’m sticking to “Goes beyond magic”, or at least what we know of it
(On a side note Sylvanas is now a better mage than Jaina or Thalyssra, maybe even Khadgar, lol)
