Alternative Source of Supply
Start NPC: Hallaj
Our scouts followed up on some of the other maps you recovered and found a strange, red structure near the center of Kaidun's base.
Sihran forces chased them off before they could examine it too closely. I need you to bring back a piece of it...or destroy it if need be.
Bloody Mana Concentrator
(With a few well-placed strikes, a small fragment of the structure breaks off.)
Interesting. This is all you could chip off? The sorcerers in the rear camp will have to look carefully at this.
Find the bloody mana concentrator at the Tyrant's Overwatch.
Deliver the fragment to Hallaj.
