The priest who casts this spell can determine the single most valuable item within the spell's area of effect. This information gained involves the item's monetary value only. Magical items are revealed to be only as valuable as the materials from which they are made. This aside, the caster learns the item's exact value (in terms of gold pieces).
For every 1,000 gp value of the item, there is a 1%cumulative chance that Abbathor himself takes notice of the item and desires it for himself. If this occurs, there is an equal chance that Abbathor sends an avatar to retrieve the object. The total chance won't exceed 95%.
The avatar's sole purpose is to retrieve the desired item and return with it to the Gray Wastes. Under no circumstances does the avatar of Abbathor become involved in the affairs of the priest. Any attempt to prevent the avatar from carrying out its duty is dealt with accordingly.
Notes: Granted by the evil dwarven deity Abbathor.
