Kal'gerion battle commendation

A Kal'gerion battle commendation is a rare drop from Kal'gerion demons. When you click the commendation it will award you with a demonic title. These titles can be unlocked in the following order: In order to unlock a demonic title, you must have killed the respective boss in a dungeoneering floor.
 * the Bloodchiller To'Kash the Bloodchiller
 * the Riftsplitter Har'Lakk the Riftsplitter
 * the Pummeler Bal'lak the Pummeller
 * the Thunderous Yk'Lagor the Thunderous
 * the Warmonger Kal'Ger the Warmonger

If you haven't killed the boss yet, you can keep the item for use later on. Battle commendations will only drop if you have titles left to unlock.
