This prized charm is a specially blessed symbol which has within it the power to affect all undead creatures as if a cleric were using his or her power to turn these monsters. 

While it appears ordinary at other times, the amulet glows brightly when presented strongly (as if it were a holy symbol) in the presence of un-dead. The success of the attempt to turn is determined as for a cleric of a certain level; the strength of each amulet varies, and when one is discovered its type is ascertained by rolling on the following table:

The amulet must be worn at all times to have it as an effective tool. When it is not worn, it becomes inert, and will remain so for the first seven days after it is put on. 

Its value is a function of its strength: 200 x.p. value per effective cleric level, and 1,000 gp sale value per effective cleric level.
