Definately an interesting idea. I like most of the components presented, though I think that any DM introducing these concepts will have to take a look at each item for balance within their own campaign. Personally, I found some that were too easy to come by for the effect that they granted (eg. Damaged by Chaotic Character or Creature), while there were some that seemed an awful lot of effort for the result provided (eg Nightmare's Hooves). Overall, though, I rather liked it.
