Apologies its been a while since i played but. . . giving current DDO players a decent way to make quick money.
I forgot which house is it (the one with the weapons broker)
The quest: Depths of Despair (pretty sure its despair)
When you first enter the dungeon if you make a left, you will see an earth elemental and spike traps. run past the elemental, make a right and there will be a chest with two sets of spike traps around it.
Idea here is to run the quest on elite, run past the earthie, jump the spikes, loot the elite loot and bail out. Disband your party and repeat till chest is dry. Additional bonus with this particular dungeon. The chest can spawn on either left or right wall. These chests count as their own private entity which means you can loot each chest 7 times. though they become crappy after about 4 loots.
I dunno if this has been posted else where, and i really dun care. Im not looking for rewards, just wanted to help the community.
