I Have an Idea, But First...

When I was in the - ahem - employ of the Lich King, we would often use a device known as a sovereign rod to keep some of the more intelligent Scourge in line. I require that you assist me in the construction of a new one. Luckily for you, all of the necessary components are at hand: a cultist rod, an abomination hook, a geist rope, and a handful of Scourge essences. This should not be difficult, <class>.
