Preemptive Strike

This is an Act 7 side quest, offered by Vorak in the Vanguard of the Three.

Korvaak's zealots are trying to release an eldritch monstrosity imprisoned within the Tomb of Ariath. Vorak proposes to release it first, and destroy it before it can gather strength.

Objectives

 * Destroy the Eastern Conduit
 * Destroy the Northern Conduit
 * Destroy the Western Conduit
 * Slay the Duskreaper
 * Speak with Vorak at the Vanguard of the Three

Guide
The Tomb of Ariath has a single entrance in the Valley of the Chosen. Destroying the three Binding Conduits will cause The Duskreaper to spawn in the central area. Defeat it and return to Vorak.
