As i said early i do like this twist on death... I think losing exp is just a stupid way to deal with it...The death realm perhaps is your souls method of trying to find its way back to your body - if you fail you die.... or put a time limit on it, if you dont get out of the death realm in less than some given amount of time your body loses any chance of being saved and then "permadeath" takes place. Another idea could be that you lose all of your equipment in the area in which you died, you were resuccitated and then have to travel out and get your equipment... if you don't get there in time and someone else finds it they can loot it - it would become free game... just a thought.
