Okay, I forgot to say this was a crafted house item in my last post of this idea, so I came back to repost it the way it should be. The "Heart in a jar" will be in the same kind of red jar as the brain is. It will be a legendary crafter only crafting item. It will contain a human heart, not the valentine shaped heart, thats not realistic. It could maybe even still be beating. I know that may sound a little graphic, but I have seen the beating heart of the skeletal dragon mount so I don't think this Heart in a jar would steer away from the E10+ rating of Wizard101.
