I counted three demons in the demon zone when my group sent looking for a heart. it stands to reason if you got all three demons you might have three hearts. Then you might be able to make the jump to the knights dimension or anywhere else. So here's the question has anyone every tried to get even two of these guys and if so did you get more than one heart.

No point in it really. All you need is one demon heart, and two wouldn't help you out any because the planar sphere's machine has no more power to make planar jumps. The only reason I've seen to gather the other two demon hearts is to upgrade your weapons. You may not have the Items Upgrade Mod Mirror, so go here to download it.

I though the heart powered the golem that in turn powered the planar sphere. Well it doesn't matter since my PC can't set the controls anyway. Understand I look for unexpected twists in the story line or odd ways to solve game problems. Like when I used the ring of earth elemental control to charm the Earth Gate guardian and then tried to walk it into the drow directly north. AND IT ALMOST WORKED!!.
