By the Blood of Trollhaugen

The Brides of Khaine revel in bloodletting, for it is only through the slaughter that we may draw near our dark lord. Armor? No, |n, we bare our flesh to the blades of our foes, yet another trap for the unwary. But do not believe that we enter battle unprepared. Each of us carries with her certain ... substances ... which provide greater speed, agility, and strength. This one was made from the blood of one of those rebels. Ah, yes. I can see it in your eyes. You wish to try a draught of the maids for yourself. Very well. To our west there is a cave filled with bestial, ravaging creatures. Gorgers they are called. Take this draught and drink it just before battle. Then lose yourself in the ecstasy that is war!

Trek west into Icefist Warren and seek out the cave that Yroltaen mentioned. Use the Burning Draught in your inventory upon reaching the cave, and destroy the Bonegash Gorgers within. Return to Yroltaen Burnblade in Trollhaugen when finished.
