An oculus of Abaddon appears as a sphere of clear crystal that contains a black void at its center. When held, the oculus feels warm to the touch and fills the holder with a sudden desire to pluck out an eye and place the oculus within the socket—this causes 1d8 points of damage, 1 point of bleed damage, and 2 points of Constitution damage. Once placed in an eye socket, the oculus can only be removed by ripping it free (causing the same amount of damage as the initial plucking). An oculus placed in an empty eye socket immediately heals all damage caused by plucking the previous eye out. Once placed, an oculus allows its new owner to utilize its powers, as listed below.

• Darkvision to a range of 120 feet (constant)
• True seeing once per day as a free action
• Greater Scrying three times per day
• Planar Binding once per week (only to summmon natives of Abaddon)
• Familiar farsight at will

The oculus of Abaddon’s greatest power, though, is its haunting beckon. This ability is usable once per year, and allows the user to manipulate the minds of a huge number of targets, provided that the end goal of the manipulation is a tragic or otherwise horrific fate for those being manipulated. This functions as mass charm monster, but with a range of 1 mile, and establishes a telepathic link between the caster and all minds in that area. The effects are still language- dependant despite this telepathy—creatures without the ability to understand language (typically, creatures with an Intelligence score of 2 or lower) are unaffected. All other creatures are automatically affected unless they have 6 or more HD, in which case they gain a DC 22 Will save to resist the effects. Spell resistance applies regardless of HD.

The oculus of Abaddon is powerfully neutral evil and possesses a limited and hateful intellect of its own. while not capable of communicating directly with its owner, it refuses to activate its powers for any user who is not neutral evil.
