I never played Dark Sun. Similar concept?
It's an interesting idea; spend a fairly high level spell slot in order to make your subsequent spells more effective, but can't move around very much.
You dont have to stay in it, you are already empowered by killing the land, its just on a 5 round timer.
I'd have to go back and see how it was implemented in Dark Sun but the theme is there.
