Roaming the lands of Tamriel are some awful and fatal diseases. What is belived to be the worst one(s) of them? Listed below are some known diseases. Reflect on witch disease that would be worst inn real life(based on the symptoms), and the most harmfull for your character/playstyle ingame.

Imo it stands between Serpiginous Dementia and corpus. Both of them altering your appearence to a ugly cripple with hallucinations.
Ingame i rather prefer not to contract anything that drain strength or health like "droops", as i always cary maximum amount of loot.

Gotta say, just going by their names, Ticklebritch and Brown Rot sound pretty bad...

Ash Chancre sounds pretty heavy, getting corpus like growth, but instead of muscle tissue gray swollen flesh

They all look pretty nasty, but I would have to say corpus is the worst.

Corprus is probably the worst, because everyone misspells it

Corprus is by far the worst.

Slowly and agonizingly having growths sprout out of your body, turning you into a monster. Having your own mind turned against you until you are no longer yourself, just a mindless slave with your 'self' dreaming an empty dream, all those memories gone and you are willing to rip open anyone (including those you used to love) on sight.

LOL!
