I don't know if anyone has tried this but...

I'm still carrying the Vamp ring around because I thought I might use it later (and it's worth a lot!). I have noticed a number of items which have the Regen characteristic, usually just +1. I can buy them back if I want 'em. Can a Vampire compensate for health loss by equiping a few such items, maybe up to Regen+3 or so? I heard wearing the Vamp ring causes crashes but I am getting attacked by a number of Succubi in the Pyramid who give me a nice nibble. It would be nice to try a Vamp without the hassle of constant healing.
