Issues I have:
a. If I stand still and go get a cup of coffee I die. I believe -1 regen should only occur when I go into "battle mode" just as normal health recover works (only opposite of coures).
b. If I fire my bow at its standard rate (short bow, long bow, doesn't seem to matter) by the time the hit has occured I've lost 2-5 life, to regain 2. Then my next firing I lose another 2-5 to regain 2. I do not understand the value of an item that heals you, but does more damage then healing. I can only imagine a +1/-1 string.
c. Is there something I'm missing? Do I need some other type of item to offset this dangerous slope. I have 5 bows, all with different strings, and that's the only one I have to change out when I get another string because I cannot afford to die and gain no type of advantage.
It seems that "upgrade" items typically make items _better_ for the user, but I'm not so sure about vampiric ones. Esp. bows since its rate of fire is so low compared to mad swinging of a sword.

Am I doing something wrong here? Or do they really server zero purpose? I'd love to know any tricks or tips if I'm in the wrong here..

PS: I bought the item assuming that a +2 drain was really a ratio where you hit for 10 then you gain 20. You hit for 1 then you gain 2, etc. Like a true "vampiric weapon" may work in other games like D&D.
