Sinking Sands

Sinking Sands is a kill quest given by Argent. It requires killing a Boss mob.

How To Achieve
Crixalis resides in large deserts, usually large enough that all its ends cannot be seen at once.

Crixalis' presence can be told by the unusually large number of Sand Storms nearby, a particularly large one is where the Sand King himself resides. Once neared, be careful. He is partially invisible, and while slow, he can cripple you with his powerful melee attacks. Remember, you must deal the killing blow to Crixalis, and not another mob, player, or environmental damage.

Once killed, return to Argent and talk to her to finish the quest.
