Perhaps a system for Necromancers to use the Create undead spell on PC bodies, allowing a fallen PC to be of some use other than as firewood, food or paperweight?
Upon being raised as a Zombie the PC would be just that, mindless, no weapons (would have been dropped on death, of course), no magic (possibly taking a leaf from the exhaustion system? reduced speed and 100% spell failure?), but all the benifits of death, immunities and the like.
I'm mainly thinking of this for the horror value of having ones loved ones or friends dissapear, only to return as a shambling corpse intent on devouring your brains. Would you be strong enough in yourself to put down your zombie husband or wife with a shovel?
This would also add more RP concequences to death instead of the standard wander around as a ghost/ wait to be ressed/ summon OOC help because the evil witch is bored and decided just to abandon the corpse. This would also allow an otherwise good PC to play a monster for a little while, albeit a limited one.
The PC would be curable with the standard Raise dead or Reserection spells. Thoughts?
