Are we reading the same doc, cuz I don't see a separate section for darkhold abilities.
I'd also believe that Wanda should get a new key for the darkhold considering that she was doing a lot of her stuff from WandaVision with significantly much more ease such as illusions, reality warping (doing it thought based instead of needing her hand flicks, and in a weaker body too), oh yeah and the entire HEX which she directly in the movie called easy (despite visually struggling with it back in WandaVision). And similar to Strange's evolution from DS1 to later MCU appearances, she should be reasonably FAR more skilled with her magic than she was in WandaVision, when the one thing she knew how to do properly was cast magic nulling runes. And her mindset is far different in general, being FAR more willing to use any of her hax in combat, something her WandaVison self did not do whatsoever.
I don't really care enough to try to argue against not making a new key tho, so go on.
