Yesterday, my questmates and I did the Church and the Cult in House P. At the end, when we did it on normal, none of us had silver weapons and the vampire took us more than 10 minutes to kill.... It just won't die, and his hps kept getting regenerating everything it seems like we had the upper hand (it had that smirk on its face). It even chased us to the shrine and won't let us heal once we resurrected. Annoying to say the least. We took a lot of damage from his fireballs attack and I think I killed my keyboard too. There must be an easier way to kill a vampire.
