There are several bonuses to stat points, which will more than make up for those lost to the vampire.
minor Spoiler
There is an object (south of the dwarven village, IIRC) which will give you either a +5 bonus or -5 penalty to one primary stat. The effect is random, so save first so you can get the bonus to the stat of your choice. There is also an item which can raise you up a level and another which can either give you a level or a stat bonus of your choice.
And just where will I find these little gems? That is if I ever get out of the death grip of the scummy butt.
