Quest giver is Head Servant Hithorin. He gives out two tasks; this item is the caster result of the task titled "Trouble with Dirt." Other is titled, "The Alley of the Damned."
This task is simple; kill 10 earth elementals near the dragon runway. Also must kill Xanthrin of Deep Strata, who spawns in the same spot. Go back and hail Head Servant Hithorin to receive reward.
Task updates everyone after a kill even if in raid format.
