Woah, I left this thread to it's own for a few days, and well, heh, It's grown.
Just to throw it out there, some of the ideas I was making up on the spot, and others were to keep some other people from whining, just a safety, don't question me.
*AHEM* The only real thing I'm sticking true with is 'hot' items, and durations. DAYS IRL is a little extensive. Maybe like half-a-day, or when the scents to the item are destroyed. All the times I put on aren't definite of my ideas, just variables that can be tweaked.
Sorry for improvising in most of the post, It's really only the 'hot' items I'm standing by.
