The literal eyes of a basilisk, forcibly transplanted into Kevorkian’s face. Kevorkian’s eye sockets had to be surgically expanded to make room for the oversized, yellow eyes. The eyes cause Kavorkian regular discomfort and near-constant headaches, but offer some considerable improvements over his original eyes (and infinite improvement over no eyes at all).

The eyes see exceptionally well. In addition to normal vision capabilities, the eyes grant Kevorkian darkvision, allowing him to see up to 60 feet in dim light as if it were bright light, and darkness as if it were dim light. The eyes also allow him to clearly see creatures within 60 feet that exist on the Ethereal plane or that are incorporeal in nature.

If a creature starts its turn within 30 feet of Kevorkian and is able to see the eyes, the creature must make a DC 10 Constitution saving throw. On a failed save, the creature magically begins to turn to stone and is restrained. It must repeat the saving throw at the end of its next turn. On a success, the effect ends. On a failure, the creature is petrified for the next 24 hours, or until freed by a greater restoration spell or similar magic. This effect extends to creatures on the ethereal plane, which are turned to etheral stone.
A creature that isn’t surprised can avert its eyes to avoid the saving throw at the start of its turn. If it does so, it can’t see Kevorkian until the start of its next turn, when it can avert its eyes again. If it looks at Kevorkian in the meantime, it must immediately make the save.
If Kevorkian sees his own reflection within 30 feet, he must make the saving throw himself.

The constant pain from having the oversized eyes stuck in his skull (and some possibly bad wiring) is very distracting and slow Kevorkian’s reactions. He suffers disadvantage on all Constitution checks made to concentrate on a spell, and suffers disadvantage on all Initiative rolls.
