As of September 2022 on the Yelinak server (in kunark era), it is very difficult to single group this item because all the target mobs are in the Chardok palace. Your only hope is to find a small raid force who are doing Chardok royals and ask them to loot this. Or hope your guild does the Overking raid for cleric epic or something.
On the "sorcerors" the item is not common. It took about 20 kills to get a single one.
