Through necromancy, when hit with what should be a fatal wound, you do not die.
Prerequisite: one talent from the Necromancy tree
Sacrifice: 2000 xp
Time Taken (At Hand): reaction (n/a)
Duration: 2 hours/level
When you are dealt a blow that would kill you, you may cast this spell as a reaction. You are not slain, even though the damage to your body remains. No matter how dire the wound, even a sword through the heart or decapitation, does not kill you. If your body is dismembered, you retain control of all the pieces, which continue to move and operate independently of your body. Your body may be so hacked to pieces that it can no longer operate, however; if it is burned to ashes, pulverized, or otherwise completely destroyed, this effectively renders your body unusable as well (although you remain "alive" until the duration of the spell ends).
During the time between the "fatal" blow and the end of the spell, you must somehow heal the wound, or you will simply die when the spell duration ends. The Manifest spell will do this; some other powerful necromantic magics will as well. A DC 40 Heal check may also work in the case of a "simple" wound (such as a skewered heart or a severed head) -- this is up to the GM.
Note that any piece of your body that is "missing" when the spell duration ends dies. If any necessary parts of you are gone, you are instantly slain.
Special: This spell may not be kept "at hand."
So far the project is some 60 pages long (in unformatted manuscript form) and practically a stand-alone game. Too bad the Saga edition isn't open gaming content, I could probably make some bucks selling this thing. ;P On the other hand, it's turning into the game I've been wanting to run for quite some time now, so it's not like I'm doing it for the money!
Next ... weapons and armor! Fortunately, there's a lot less work to be done there!
