Aorry to bring this up again, but I've found that you don't lose attribute points randomly form being bitten by the vampire. I tried it three times in a row and lost the same seven points each time:
- 4 Strength
- 2 Agility
- 1 Inteligence
- 0 Constitution
I think it is pobably related to your Constitution, as I have a Constitution of 12 (even though I'm level 18!).
Come to think of it, has anyone lost Constitution to the vampire?
