- "Carved of human bone, the Whistle of Warding is a favorite artifact of the practicing Necromancer. The enchantments placed upon the item allow its possessor to invoke its magic simply by blowing a tune on the whistle. The whistle can only be blown one time, for once its enchantment is released, its power is spent and the item crumbles to dust."
The Whistle of Warding is an unused item in Planescape: Torment 's game files.
