Okay so I have played skyrim as a warewolf, completed the Dawnguard extension and remained a warewolf.

I was playing 'Lost to the Ages' quest and reached the forge and was fighting the guardians, my screen flashed purple and told me that due to my vampiric blood i have a -20% weakness to fire. I tried healing my self at a shrine but it didn't help.

Now I am confused as to what I am because when I go into the sun, it boils my blood, I have gained the Champion of the night, Nightstalkers footsteps and weakness to fire Effects and the Vampires servant Power, but I still have the Beast form power.

If anyone knows why/how this happened or if it's fixable, please let me know.

You are on the wrong forums, as a note. The Dawnguard forums are this way -> http://www.gamesas.com/forum/197-dawnguard-general-discussion/

Thanks.

Always a pleasure.
