There was a link to a somewhat old blog post about 10 wizard illnesses/diseases that I saved and then lost the link. Does anyone have it? They were really creative and the writer had published a bunch of stuff on Drive Thru RPG. Might have been D&D or OSR.
One of them involved a contagious disease that eats your spell slots one by one and when you lose all of them you transform into a froglike creature that only says one word?
It isn’t, but that is similar and I’ll check it out.
