I was thinking about the plagued corruption and a few questions came to mind in terms of its interactions.
1. Can creatures immune to disease acquire the plagued corruption? While the catalyst involves suffering magical disease for a prologued period of time, the corruption also states you lose any immunity to disease.
2. How does the corruption interact with the Plaguebringer class feature? It isn't immunity to disease, but it does grant antipaladins immunity to damage and penalties resulting from diseases.
