I think that is most of the info of Allakhazam, hope it helps.
*NOTE* It appears a high percentage of the Karnor's loot was zone-wide random or trash random as well as certain named mobs.
This appears to be especially true for some of the "Kunark Class Armor" peices that dropped there, which include various classes boots, gauntlets, vambraces etc...more of them may have dropped this way and were just not reported to lucy / allak? Hard to say.
