Talisman of Secrets

 The Talisman of Secrets

   This amulet appears as a rather plan wooden disk inscribed in the center with a Penrose
   triangle and around the edges with characters that appear to be from ancient Flan.
   However the disk is harder than iron and near impossible to destroy or even mark.
   The script around the edges seems to be some saying or long phrase, or perhaps a code. 

   It is rumored that this powerful magic item was created by Vecna himself when he was
   a mortal and it is considered a holy relic of the Cult of Vecna. Any member of the Cult
   will immediately recognize the Talisman if they see it and go to great lengths to recover
   it for themselves.

   The Talisman has three powers:
      First, anyone attempting to understand the writing around the edge of the amulet must
         make a DC 20 Will save or permanently loose a point of Wisdom.

      Second, it blocks all divinations directed at the wearer such as ESP, Detect Evil, Detect
         Lie, Mind Reading, and Know Alignment.

      Third, it the target of a divination, the wearer may make a saving throw against the
         effect (even if it normally does not allow saving throws), if the save fails then the
         divination is blocked normally as per the second power above, but if the save is
         successful then the wearer gains some control over the divination attempt and is able
         to provide false results back to the diviner. The DM may require that the wearer make
         a bluff check against the diviner’s sense motive check to determine how believable
         the falsified information is.

   Example 1: A cleric casts Know Alignment on the wearer of the Talisman who is
      impersonating a paladin of Heironeous. The wearer makes their will save, becoming
      aware of the attempt and feeds back a reading of Lawful Good to the cleric. The DM
      decides that since this was what the cleric would expect of a paladin, no bluff check
      is needed.  

   Example 2: A wizard casts ESP and attempts to read the wearer’s mind. The wearer fails
      his will save and so is not aware of the attempt, but the wizard gains no information.

   Example 3: Another wizard uses a crystal ball to scry on the wearer while he is looting a
      temple of St. Cuthbert. The wearer succeeds on his will save and is aware that someone
      is scrying on him. He sends back an image of himself asleep in an inn. The DM decides
      that since the wizard had information that the wearer was in the temple a bluff check is
      needed with a -4 modifier.
