A PINCH OF ASHES
Walkthrough
Whilst exploring the Korcari Wilds as part of the Tainted Blood and The Grey Wardens' Cache main quests, you find a Dead Soldier who was sent to the Wilds with some interesting information about local myths and legends.

At location A on the map provided, you'll come across a hell of a fight, one that's outlined in the main walkthrough for the game. You'll be assailed by Genlocks and Hurlocks of all varieties here, and even your robust party of four will have a difficult time surviving the fray with your usual button-mashing tactics. When all is quiet and the enemies are felled, begin to scour the hostiles' bodies. You'll find a body mixed in the bunch that's actually a friendly human soldier. When you search his body, you'll find, amongst other goods, a sack of ashes of another soldier. With these in hand, this brief side quest will begin in earnest.
Work your way up to location B on the map once you've retrieved the ashes from the body at location A. You'll find a pile of rocks with ashes already strewn over them. The game will give you the option to spread the ashes you just found on the rocks; do this. This will summon forth a beast known as Gazarath. Gazarath is a powerful enemy, with the ability to shoot fire attacks that damage the entire party, and with an even peskier ability to siphon your health and make it his own. Nonetheless, the four-on-one odds of this battle put things firmly in your favor, so unleash your best attacks and take this foe down. Then, scour its paltry remains to find some items worth adding to your inventory.
