Quest:From Whence He Came

Objectives
Weaken Archduke Calcinder, then use the Sanctified Tripetricine to banish him. Provided item: Consecrated Tripetricine
 * banished

Description
Archduke Calcinder squirms in the back of this very cavern. We are close to killing him.. but that is not what we are going to do.

Slaying Calcinder here means nothing. His acolytes can easily revive him. Instead, we are going to banish him.

I asked you to gather a precious stone from the Twilight's Hammer earlier. You will now use it against Calcinder. Engage him, weaken him, then use this device on him. He will be banished from this realm.

Good luck, brave.

("I won't stand to have any minion of this close to Thorium Point. Send him back where he belongs.")

Completion
Archduke Calcinder has been banished from Azeroth. All that remains is a small, ashy spot where he once stood.

Your work here is done.
