Ok Anteaus, This is a perfectly simple idea. I think you didn't read it carefully.
Let's say your the average power-hungry-villain. Nothing to be ashamed about, my players took that role. Now, Somone had built a machine that can turn you into a demon, and grant you their powers. Before this can happen they need the flesh of a demon to do this. They also want the skin of three humans so you can still look like a human after you have transformed. If you would rahter look like a skinned demon though, that's up to you. After you go into the device, you are the one demon and have a demons powers. But the flesh they used to transform you is dead, so it will rot. As I mentioned before, it will only last for three days...and I want you to pay close attention to this part becuase you missed it before, it will only last three days unless it is somehow preserved. Either through a spell or application of the acids used to graft it onto you.
The overall point is you, or your players should you be a GM, are just normal people who kill off one demon and three humans and become powerful for a time. The flesh rotting is mostly for balance.
Brrrr, low marks becuase you think it's gross Cheka....so cold.
Echo, I know it could use some work. And for that I'm sorry but I'm not sure just how I could polish this one.
As for the process, I intentionally left it out. I wanted to avoid the low marks for gratuitous amounts of information on the way it happens.
To truly understand the reasons it was built you would have to get a complete understanding of the capmain the Lucint came from. Which is a long story...too long.
As for your variations. I suppose it could just add on individual parts. Such as claws or skin, maybe teeth as well. Or perhaps it could give a man a resistance to acid if you take away the flesh additive. Go to Comment
This is an interesting item in and of itself. Though I am having a small bit of trouble thinking of pratical uses for this. I imagine it would be quite large so it's not as if the players could take it with them. Which would mean that they would either have to travel back to it constantly, or if there was some way a player could tap into one of the crystals and tell it what to send from a distance it would be easier too.
Another issue would be that they are ony keyed to one other crystal, which means that even if the device were common it doesn't help much.
With a few minor tweaks though, this could be quite the creation. Go to Comment
I was thinking have the effects end when the amulet is removed.
So naturally a smart man would remove it immediatly. That is if he doesn't think the spell simply failed.
Having it appear to work from the casters point of view is an interesting idea. Though I'm sure he would be a bit confused as to why an enemies hair is blowing when a fireball smashed into him. He would also look insane to his allies and enemies alike. Go to Comment
Echo, I threw in the costom made bow for a reason. This thing is big. I was thinking the size of a large firework. Though I do like the idea of the rocket having more of a sharpel effect on it's enemies. Go to Comment
You receive a vision of a rooftop "somewhere close by", where a rare moss grows; in the vision, you know the moss is suitable for greatly enhancing the effects of certain types of potions. Now go and find that rooftop. Don't fall off. (Of course, rooftop runners *will* be taken for miscreants by the local City Watch....)
