Bio-Optic Killshades

Bio-Optic Killshades are a variety of head-worn items created by Engineers with a minimum skill of 75 in Cataclysm Engineering. Each class is offered training to create only a select variety of these, usually limited to a single type.

All versions of Bio-Optic Killshades have two Cogwheel Sockets, allowing two Cogwheel gems (and only cogwheel gems) to be installed. Note that all Cogwheel gems are unique-equipped, meaning that only one of that type of gem may operate at a time.

While they all require a minimum character level of 81 to wear, they require a Chaos Orb to create, which requires a minimum level of 85 to loot, although these can be traded or bought on the AH.
