Agatha's mask

Agatha's mask is a magical item of illusion.

Appearance
Agatha's mask is a plain white stage mask with a simple cord to hold it in place.

Magical Properties
When worn the masks magic bestows on the wearer the illusionary appearance of another race or a monster. This effect only works as long as the mask is worn and is only effective to the naked eye; any magical scrutiny will reveal the true identity of the wearer.

History
For a long time, the mask was in possession of the banshee Agatha.

When the drow Drizzt Do'Urden was in need of a way to enter the city of Calimshan without letting anyone know of his drow heritage, he and his barbarian friend Wulfgar learned of an item in the possession of the banshee Agatha which could help them with their task. They went and aquired the mask without killing the banshee on request of nearby villagers of Conyberry, who benefited from the banshee living in the area.

Drizzt gives the mask to Regis, when the halfling becomes the Pook thieves guild's new master. Artemis Entreri takes possession of the mask from the halfling, and transformed into Regis visits Mithral Hall, seeking a rematch with Drizzt. In the end of this story Entreri is found by Regis critically injured. Full of hatred, Regis steals the mask as well as all other magical possessions, and leaves Entreri to die. When Drizzt is getting himself ready for going to Menzoberranzan, Regis offers him Agatha's mask, retrieved from Entreri's body, but Drizzt turns down the offer. The same offer is soon afterwards made to Catti-brie, when she leaves in pursuit of Drizzt. She accepts and uses the mask to take on a drow aspect. Although she loses control over the mask for a short period of time to Jarlaxle, she eventually returns from the Underdark with the mask.

Jarlaxle uses the same technique as Drizzt Do'Urden to visit Memnon.
