Quest: Fierce Effect of Duty
Location Map:
The Velerium Mines

Ok so now you should have the 20 piece of Velerium Ore and the Sleuth Data. Head back to Dharrek Anshaw, he will be most displeased with the amount of time it took you to get back to him. He takes the data and looks it over with a grim face. If this data is correct, then immediate action must be taken. Apparently you have been collecting components for a recipe this whole time, and according to the recipe, there mentions a special component the Sithar Lord carries. Your task will be to slay the Sithar Lord! Unfortunately the Sithar Lord doesn't make common appearances to his followers. You will need to slay 60 of the Sithar located inside of the Mine. After you have done this, you will need to go to the Throne Room, where you will need to place the berlucite that you collected onto the alter there. This will draw out Sahgridar The Overlord!
Well this is no easy task, so definitely bring some extra people along for the ride! Go into the mines and slay any Sithar that you see. Once you have slayed your 60 Sithar head to the room where the Sithar Herald stands in front of a chair, this will be the Throne Room.
NOTE: Watch out for Rashnok Assassins, as they will be free to roam the Sithar side of the Mine if you have killed all the Sithar. They will attack you and add to the final fight if they get too close.

You will notice in this room that there is an alter in the middle, with a bluish circle thing dancing on top of it. When your group has cleared this room of the mobs, you will need to right click the alter on the floor to place the berlicute onto it. This will spawn Xhalaphir, Arm of Sahgridar (around level 44 4dot), along with 2 Elite Champions (around level 44 3dot). Your group will need to slay the 3 mobs as fast as possible, as while you are killing them, something starts to appear by the throne!
Now as you are killing Xhalaphir, you will notice something burst near the throne, causing a gigantic puff of smoke to cover that whole side of the room. When this happens you know Sahgridar is almost ready to make his appearance. When the smoke goes away, there in it's place will lie Sahgridar The Overlord (around level 44 5dot), along with 2 of his best Sithar Warriors (around level 44 3dot).

This fight will be a bit harder than the Xhalaphir fight, but not by much. So have some fun with this fight and make sure Sahgridar goes down (punch him once for me!). When he goes down, make sure you loot the
Sithar Lord's Stash. This is his secret stash he keeps on him for some reason! I wonder what's inside the stash! Well, you can right click it and find out. So go ahead and right click his stash. Presto, you have now uncovered 2 items. The two item are called
Vial of Pure Vulmane Blood and
Sahgridar's Broken Mask. Both item will be used towards making the Mask of the Feral Warrior, so do NOT destroy them by accident.
Head back to Dharrek Anshaw. He will be extremely surprised to find that Sahgridar had Pure Vumane blood! At least you have defeated him for now, but Dharrek expects that Sahgridar will be back, but at least he won't have his mask, nor the blood. Darrek will be pleased with your work, and offer you the
Mask of the Feral Warrior Recipe as a reward.
