So I did a lot of the DB quests so I could get to the point where you can pick up a free 'Worn Shrouded Cowel' that I could enchant with fortify destruction and restoration to go with my black robes.
I also enchanted other items with 'Fire Resistance' and it took me ages to finally get infected with the vampire disease.
You see, I thought being a vampire would be the same as in Oblivion, where if you fast travel and arrive at your destination during the daytime, then your Health Bar would go down very quickly and if you didn't get inside a building within 15 or 20 seconds then you would die!
But oh no, in Skyrim, a vampire can stand out in the sunlight and wear any clothing and doesn't die. Only has 60 points taken off health/magic/stamina which don't regenerate in sunlight (but my magicka did?), a -100% weakness to fire and at level 4 vampirism gets attacked.
What a huge waste of time.
