Having high alchemy and restoration magic (but almost none of the other magics, as I use those for support only)
I find it somewhat dull, if I hardly ever use those other than for healing my normal health.
As said : in morrowind there were multiple types of illness. (blight based one's, normal one's, and some special once's) so you always kept a couple of healing pots for illness on you.
However in Oblivion... it is near impossible to get any illness. I have litterly tried to stand in the mids of a den of vampires, only healing myself over and over, having 5 of them bashing in on me... no illness.
Nor does any other monster give me any illness.. no skeleton, no troll, no bear no nothing.
In Morrowind one would get a normal disease as a highelve 1 in 80 fights (each of about 5 hits, so say 1 in 400 hits, ofcourse in that game you could SEE if a being was infected.. it would list "diseased whatever" in oblivion.. not so clear)
nevertheless it also made sence, for normal chars without this highelve boost, indeed 1 in 20 fights gave an illness, or 1 in 100 hits.
I must have been hit like 30000 times now (not counting the hits that were ranged, only the normal close combat ones)
but I still have not distracted even ONE disease..
How can this be?
For all clearety I do not want to become a vampire, all I want is to get sick now and than as it should be and as I'm used from morrowind.
