Blood and Ice
Talisman of Reluctant Wishes
A talisman of this sort appears the same as a stone of controlling earth elementals. Its powers are quite different, however, and dependent on the Charisma of the individual holding the talisman. Whenever a character touches a talisman of reluctant wishes, he must make a DC 15 Charisma check.
If he fails, the device acts as a stone of weight. Discarding or destroying it results in 5d6 points of damage to the character and the disappearance of the talisman.
If he succeeds, the talisman remains with the character for 5d6 hours, or until a wish is made with it, whichever comes first. It then disappears.
If he rolls a natural 20, the character finds it impossible to be rid of the talisman for as many months as he has points of Charisma. In addition, the artifact grants him one wish for every 6 points of the character’s Charisma. It also grows warm and throbs whenever its possessor comes within 20 feet of a mechanical or magic trap. (If the talisman is not held, its warning heat and pulses are of no avail.)
Regardless of which reaction results, a talisman of reluctant wishes disappears when its time period expires, leaving behind a 10,000 gp diamond in its stead.
