Agatha's mask

Agatha's mask was a magical item of illusion.

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

Magical Properties
When worn, the mask bestowed on the wearer the illusionary appearance of another race or monster. This effect only worked as long as the mask was worn and only effective to the naked eye; any magical scrutiny would reveal the true identity of the wearer.

History
For a long time, the mask was in possession of the banshee, Agatha. In 1356 DR, the drow, Drizzt Do'Urden, needed a way to enter the city of Calimshan without anyone knowing of his dark elf heritage. He and his barbarian friend, Wulfgar, acquired the mask without killing the banshee on request of nearby villagers of Conyberry. Near the end of 1356 DR, Drizzt gave the mask to Regis, when the halfling became the Pook thieves' guildmaster. In 1357 DR, Artemis Entreri took possession of the mask from the halfling. While seeking a rematch with Drizzt, Entreri transforms himself into Regis on a visit to Mithral Hall. In the end of R.A. Salvatore's The Legacy, Entreri is critically injured and left hanging on a cliff, after Regis steals the mask and other magical possessions of Entreri. Later in the year, Regis offers Drizzt the mask to help him on his journey to Menzoberranzan, but Drizzt turns down the offer. Later, Catti-brie takes the mask to aid her in pursuing Drizzt, by disguising herself as a drow female. She lost control over the mask and it fell into Jarlaxle's hands, but she eventually returned from the Underdark with the mask. In 1368 DR, Jarlaxle used the same technique as Drizzt Do'Urden to visit Memnon.
