Allowed items: ring, amulet, wristlet
This spell grants item the power to make its wearer invisible. The effect
is basically the same as powerinvisibility spell, only it is provided to the
character by conjured item instead of an enchant, so the user either has to
remove the item (destroying it in the process as it is conjured and vanishes
when unequipped) or purge the power from the item, if she wants to become
visible. If you wonder why it may be needed to get rid of invisibility, just
remember that most shopkeepers won\'t trade with invisible characters.
