Spiritlink

Syntax: cast spiritlink <item>
Prerequisites: consecrate

When prayed upon, a bond can be formed with an object while maintaining direct contact. With this spiritlink, any damage that would have been done to the object will instead be transferred to the person. (There is a chance of failure in making this bond and it is more severe against destructive spells.)

     'With a prayer, the cleric did care for the sacred Chalice of
      Goliott.  Tul-Sith be merciful.  Tul-Sith be praised.'
                            - Book of Tul-Sith, Chapter 2, Verse 12

Keep in mind, once you stow an item in a container or drop it, the bond is immediately broken.
