A gleeok head is the literal decapitated but still animated head of a gleeok. It is usually only created as a last resort by a gleeok, which magically separates one of its heads into this glowing, hovering undead skull. One of these heads can nonetheless persist on its own under unusual circumstances—most likely, the gleeok which created it yet lives.
