Circlet of Barbed Vision

The Circlet of Barbed Vision is one of the Vestiges of Divergence. Upon wearing this circlet of gnarled onyx, black barbs dig into the wearer's head, imparting power as it twists the wearer's appearance to amuse the Spider Queen.

History
The Circlet of Barbed Vision was robbed from the Blightstar in 842 PD by the Exandria Unlimited party. The item actively repulsed characters of good alignment who got too close, causing them to vomit black ichor. Additionally, the circlet gave Opal a vision of spiders and one large spider leg that reminded everyone else in the party of Lolth, and Dorian Storm was specifically reminded of the Vestiges of Divergence. After touching the Circlet, Dariax Zaveon's eyes turned completely black and stayed black for days; when he looked in a mirror, he saw spiders skittering across the faces of the people around him.

Later, the party encountered a forlarren resembling Fearne Calloway who had put on the circlet and become more powerful.
