Humans may dwell here

By the way, you mentioned here that the "Philactery" ability disappears after it activates. Does this mean that it has to be re-learned and that it costs experience points to do so? How complex is the process of creating a philactery, and does it cost the mage anything other than the item that becomes the new vessel for the soul? What limitations exist regarding new bodies?
