>>115479944>Thompson seems to have almost jumped the rails by having her be a flat reality warper in her the star mini rather than a magician with rules.
Her original power is straight-up probability manipulation=low-key reality altering which, because Wundagore and Chthon, she would originally instinctively use to throw chaos magic energy around.
Over time she did learn to use formal magic, giving her a better control on her powers, both magic and reality altering.
Note: magic and reality altering are very closely tied in marvel cosmology; for all purposes and intents, magic is just a(many) specific way(s) to alter reality, usually by borrowing power from higher-dimensional beings who have the ability to manipulate specific elements of reality. For a cost.
Wanda is the chosen avatar of Chthon, so she empowers him every time she uses chaos magic, which was one of the reasons for her formal magic training, to get her use different magic sources.
