- "Through the vial's glass you can feel the warlord's blood swirling."
Blood of Zul'jin drops from Zul'jin in Zul'Aman. It starts Blood of the Warlord, which rewards 10 
(and a bit of personal amusement). There is only one drop per kill.
Rare to Epic
When Zul'Aman opened, the Blood of Zul'jin was a rare drop; in Patch 2.3.2, it became an epic drop, much like the other "parts of bosses" (Kael'thas' 
[Verdant Sphere], Magtheridon's Head, etc.)
