Stefan at Ebon Watch wants you to perform another task for Drakuru. Additionally, you are to use the Explosive Charges on 5 Scourgewagons at the Reliquary of Pain. If you lose your Ensorcelled Choker, return to Stefan at Ebon Watch to get another.
5x Scourgewagons destroyed
1x Drakuru's task complete
1x Learn Drakuru's secret
While we're working to discover the purpose of these crystals, we need you back in Voltarus doing Drakuru's bidding.
Every task you perform successfully gets you closer to him, and brings us that much nearer to knowing his mind.
While you're there, I have another mission for you. Drakuru's Scourgewagons pose a significant threat. We need them destroyed.
Make your way to the wagons and activate these charges. Once they're set, get clear! The explosion will expose you if you're too close.
