Sorry, I didnt mean usable as in VE, just RPing
I dont remember who said it, and for some reason cant find it now, but it there was an idea of actually using items : a silver bar is used, and the silver bar is not whole anymore, or if its completely used, is gone. Like wise, if a vial of blood/potion were used, the vial would be either half empty or completely empty. I agree with this idea, because it makes room for more interesting ideas, to see who can make what with the limited items we have already. ((As for the healing blood again - there is one last restriction on it. You have to get the blood as close to the 'patient's' heart as possible so it can be pumped to all regions of the body. It's usually only used for dire cases Too God-Modd-ish? ))
