There already is a penalty system in place. Raise Dead has expensive components, and even then, you lose a level, or if you are level 1, 2 points of Constitution. Even then, it requires a mostly intact body. Reincarnate is better, but there is no control over what the target is reincarnated as.<br/><br/>More powerful means of resurrection cost more, and only the most expensive do not require any body part at all. Still, 25,000 GP in diamonds each time you get digested is a hefty price tag.
