During the Zatanna Arc of Season 4 we see a lot of magic and so my questions are regarding it.

Previously you told us the specialisms of Black Briarthorn, Felix Faust, Wotan and Wizard.

1. The Specialisms of Khalid seems to be biological manipulation which given his role as a Doctor fits. Is his knowledge as a Doctor a requirement for that kind of magic or does it at least enhance his skill at performing that kind of magic?
2. How did Traci settle on her Urban Magic specialism given her initial talent was at Bad Luck Magic?
3. Mary seems to be an absorber of magic, is this her specialism, is it tied to her connections to Sergeant Marvel or is it a thing all Sorcerers can do?
4. Are Khalid, Traci and Zatanna Homo Magi meaning they can use their Vim Vitai to perform Sorcery whereas Mary Marvel is Homo Sapien so must take magic from elsewhere to perform Sorcery?
5. Through the Crown of Arion all the magic we know of in the show has derived from the Lords of Order through to the Homo Magi with the exception of Klarion. Of course we don't know the source of some magic such as Neptune's Trident and The Sword of Beowulf. Are there other sources of magic or are Lords of Order and Chaos the ultimate source for all magic?
