Dark Coffer Run Guide

Dark Coffer is at The Vault room in the BRD instance. It contains a few mats for some Libram's enchants. To get them you need to go there and open it with the key. The key drops from the Dark Keeper Boss you should find... The most valuable enchant for MC runs is Fire Resist (FR) one with Libram of Resilience, which adds +20FR to Head or Legs, so you could get +40FR to your gear. One of the mats - Burning Essence - could be found inside of that Dark Coffer.

Coffer Run could be done by any group of 5 lvl 60 experienced players. Indeed holy trinity (warrior/mage/priest) as a part of a group makes it easier. It could be done in raid as well. The key point is not to aggro arena spectators - just hug the barrier and cross the area without getting any aggro.

Fight your way to the Vault room (#8 on the map below) after you cross arena, click on Portrait in the Vault room – it opens and triggers the spawn of Key Keeper at the appropriate location. Now read the description clicking on caption – it gives you the name of the Key Keeper boss and a hint to his location.

There are 6 Key Keeper bosses (only 1 spawns during your run):
Dark Keeper Bethek, Dark Keeper Ofgut, Dark Keeper Pelver, Dark Keeper Uggel , Dark Keeper Vorfalk and Dark Keeper Zimrel. Each of them spawns at the certain location but who exactly will be spawned during your run is purely random.

You need to find him, kill and loot that key. Please do not forget to change loot to Free-For-All so that any person could loot Dark Keeper Key.

Locations of Dark Keepers:
Dark Keeper Bethek (52 - 55)+
? ? ? (Location is unknown, existance of Bethek needs to be confirmed)

Dark Keeper Ofgut (54 - 55)+
Ofgut can be found next to General Angerforge (#13 on the map).

Dark Keeper Pelver (51 - 55)+
Pelver could be found in a small room at Domicile. In fact you were cleaning up your way to coffer room through Domicile and if you go left wall that room is to your right just before the stairs. In other words, the "Domicile" is back out to the left up the stairs when you leave coffer room.

Dark Keeper Uggel (55)+
In the room next to the coffer one (to the right when you exit from coffer room) in so called Hall of Crafting.

Dark Keeper Vorfalk (54 - 55)+
Located in the corner of the Grim Guzzler (bar area). Strategy is the same as for clearing around Plugger- drop Dark Iron Ales to clear patrons, pulling them to the bridge area. Finally Vorfalk will be left with 1 or 2 patrons.
Fighting in lower bar triggers the investigation alert (fire elemental + 2 guards) at the Bar Door, but the patrons all remained neutral after the fights and even after killing the Dark Keeper.

Dark Keeper Zimrel (50 - 55)+
Located between spectators at second level of arena (south part), you need to pull a group of spectators that is close to the exit from arena (use AoE alot and watch for runners) and then kill Keeper and his adds.

As soon as you get the Key go back to the Vault room and open Dark Coffer, there will be several loot items in there, burning essence could be there (there were several runs since patch 1.8 when there was no essence in coffer). There could be more than one essence in coffer, I got that once, but you canNOT give it to 2 persons in a group or raid - burning essence is soulbound. So someone could be very lucky to get 2 of those during one run. You could roll on it or do another runs until all ppl in your group get it. Usually run takes about 30-45 mins, depending on Dark Keeper location.

NB! Burning essence is soulbound and stackable (means you can have more than 1)

You could also get Black Blood of the Tormented (stackable) and Eye of Kajal (unstackable) from Dark Coffer - those are mats for another Libram's Enchants: blood is for libram of rumination (+150 mana to head or legs), eye is for libram of tenacity (+125 armor to head or legs).

You could also open Relic Coffers with Relic Coffers Keys, but only 11 out of 12. Opening all will trigger an event of the quest The Heart of the Mountain - you will need to fight with the boss and adds in that room then.

Good luck!
