The same night as after saving Katie, and after a small nap, I had started the process of brewing the Maladictus cure potion. Luckily, with the way I had designed the potion, it was mostly hands off. Similar to the Polyjuice potion. I would only need to visit it nightly to check it and a couple of changes if needed. Having my old cauldron with a self stirring enchantment was a time saver.
