Hello fellow wizards🧙
I suggest a horcrux challenge! Preferably run over a period of time to mimic the extended drama and adventures of the horcrux searches in the book. There could be one registry page with items related to each of the seven horcruxes. Destruction of each horcrux would complete (or prestige) the registry page. Then, there would be and a final challenge, with rewards, when all seven pages are completed. The horcuxes may not obviously relate to the calamity story, but I feel the game needs to be reenergized with a strong dramatic connection to the books and movies.
