Er, correct me if I'm wrong, but the cure /minor/ wounds that the original post called for was just to stop the character from bleeding, correct? In that case, I would say that the item would be very cheap...cheaper than the periapt, at least, because it doesn't have any alternate uses, and it only cures 1 hit point. Also, there is some precedent for the cure light wounds item...the renewal domain in FR (i think) gives this very same ability. I really don't think that it would be worth so many thousands of gp, either...or at least the cure minor wounds wouldn't. Also, another thing to consider...who is going to have contingency and cure minor wounds? There aren't too many level 11+ wizards who also have a divine spellcasting class, so I hope your DM isn't very tough on things like that for the availability of items (it does make sense that those are the prereqs, but perhaps they could be eased a bit considering the periapt of wound closure only has heal as a prereq...)
ive got to stop checking the boards at 3 in the morning
