Submission Through Suffering

Part of the City Tasks timeline located in Nektulos Forrest. You get the quest from Occultist Levonicus of the Dismal Rage in Freeport. You have to slay 15 Dragoon Sentinels of the Teir 'Dal(700,12,-735). I have only seen them spawn at night, but that might simply be a timing issue on my part.
