This magic item takes the form of a small silver pin or medallion, shaped into the form of a necromantic sigil. A Good test of divination magic will reveal the item is enchanted with Superb necromantic and protection magics. A Great test of divination magic will reveal the process of attunement required to activate the item's protective magic.
To attune the item the owner must procure a flawless ruby of Great value, place it within a crystal container, then drench it in their own blood (at least one pint). The container is then sealed and placed in a secure location. The owner then keeps the sigil on their person at all times.
Should the owner be slain, the sigil will transfer the owner's life essence to the sealed vessel. The contained ruby and blood will burst forth and begin to form a new body for the transferred life essence. It will take one week for the new body to take shape. Once complete the new body is identical to the original in all regards, save any diseases, curses or poisons affecting the original will no longer be in effect.
The process of transference destroys the sigil.
