Of Diamonds and Demons

Another notable quest available is “Of Diamonds and Demons“ (“DnD“). The quest can be picked up from the following NPCs:

REALM	LOCATION	NPC
Albion	Darkness Falls or Brimstone Caverns	Jenjen
Hibernia	Darkness Falls or Caves of Cruachan	Riesie
Midgard	Darkness Falls or Halls of Helgardh	Haelgi

This quest will see you travelling through the depths of Darkness Falls or your realm’s CL5 dungeon in order to slay a variety of high level demons. This quest requires a group.

Umbrood Warriors, Succubi and Nightmares are all very easy to encounter when just travelling through the higher level areas of Darkness Falls. Chthonian Crawlers are slightly rarer and may take a bit longer to get ten kills. Umbral Hulks are all located in the same place: At the bottom of the large pit at the crossroads where all three realms intersect. The problem with them is that the pit is also one of the most popular farming spots in the game and will frequently be camped by other players.

The quest rewards players with the “Sphere of the Damned” and either the “Bracer of Sudden Finality,” “Belt of Consumed Souls,” “Ring of the Claimed” or the “Cloak of the Highwayman” depending on your class, as well as a choice of headpiece with a unique “pointy wizard hat” appearance.
