Game changed quite a bit from the more cynical v1/2.1.
Also are we going to a "Wheel of Time (Book)" kinda magic issue one piece of worldbuilding sticks out to me, Ms.Lilith said that magic has become "unprofitable", but things like the swiss army combat knife that is a wand and easy to store (when not stolen and broken) brooms seem to be pretty useful for a myriad of purposes. So my guess is that it is something else and that something is that the witches are just plain weaker than they could be. The girls seem to have some issue levitating a banana, the demon can't transform for that long before meeting the MC. After their oral exchange, she could only transform for days on end she also had enough juice left over to burn the shortstacks berries. There is also the fact that the MC seems to take to the magic alot more easily than Jade, who we can assume has similar amount of magics training (if not quickdraw training).
Probably gonna be explained later and this will end up just being one of my maddened ramblings.
