The final act felt very rushed, and the ending it was building towards basically ruined the entire show for me, and made me feel like I wasted my time. Blocking white people from using magic shouldn't even be a possible spell due to how incredibly vague it is, and even if it was possible, how white does someone need to be for it to not work? There are children in India, born to seemingly entirely Indian parents, but has white skin, can they learn magic? What if someone's 75% white but has black skin, can they use magic? It doesn't make any sense!
