A little rules alteration suggested for Glass Magic. I rather feel that it's too harsh on unordained casters, too lax on the priests. So I propose the following:
A Caster who loses their last Psyche hit by casting Glass Magic immediately has one of their locations transformed into glass. A location that is transformed to glass loses one hit permenantly, and all damage to a glass location counts as Through damage. Damage to a glass location can be healed only by the vitrified individual spending one Psyche hit per hit to be restored.
If the caster is an ordained priest of the Vitriarchs, the glass is living and mobile. If they are not it is cold and inert.
If all of your locations have become Glass, then hitting 0 Psyche hits deals you one damage to the torso.
