Magic Stone (Theurgy) [Earth]
Level: Priest 2, Earth 1
Mana: 15. Persistant. Base Success: 90%.
  Casting this spell allows a priest to briefly awaken the spirit of any one stone (or stack of stones) of hand-held size or smaller. This can have any one of the four following effects:
   Stone Bolt: A mundane rock or sling bullet (or stack thereof), is transformed into a powerful magical missile: a +1 thundering weapon. The magical plus increases by one for every three caster levels the caster possesses.
   Stone Lore: The caster speaks with the stone, learning its nature -- this form of the spell works to identify any magical stone, rock or sling bullet it is cast upon.
   Stone Ration: This form of the magic renders the affected stone edible (by creatures that can normally subsist on vegetable matter). A priest can survive and even sustain a small group in times of privation in this manner, but in the long run eating stones has an adverse effect on one's health.
   Stone Sentinel: This form of the casting briefly animates the rock, turning it into a tiny stone figure called a stone sentinel. Such a creature is very weak, being less than a foot tall, but is difficult to hit and may serve as a useful distraction in a time of need.
