Empowered Nether Crucible
Empowered Nether Crucible is a Nether Crucible situated at the Fel Hammer. The pool of felblood is more powerful than any the Illidari had crafted before, the souls of the hundreds of slain demons in Mardum powering it.
"The fel blood froths violently, a swirl of obfuscated shapes bubbling just below the surface"
