Blackrock Depths Dark Iron stealth mining guide Introduction . Since the only other guide I could find hasn ' t been updated in a long time , I thought it ' d be a nice idea to expand and update on this . If you are a Miner , Dark Iron Ore can be obtained if you have 230 mining skill . Dark iron veins spawn in Blackrock Depths and Molten Core . It no longer can be found in Searing Gorge or the Burning Steppes . Dark Iron veins can produce : Requirements . To successfully farm Dark Iron you need the following : Recommended . As an extra you could get the following items to speed up your farming : Resetting the Instance . As of 1 . 11 you can reset the instance by right - clicking your portrait while outside the instance , then clicking the " reset all instances " option . Limitations . As of Patch 1 . 9 or so , you are limited to 5 instances per hour . Meaning that if you start your first run at 13 . 00 , and do 4 more runs before it is 14 . 00 , you will not be able to enter any instance ( aside from Battlegrounds ) until it is 14 . 00 . Because of this limitation you can either take your time and get as much Dark Iron as you can within those 60 minutes ( 12 Minutes per run ) , or rush and mine only close to the instance entrance within 30 minutes , then spend the other 30 minutes farming for Dark Iron in Searing Gorge or Burning Steppes . Try to get CT _ Timermod , as it can help you time your runs . During those 5 instances , you should be able to gather between 30 - 50 Dark iron , since you can get anywhere from 1 - 5 nodes successfully per run . Also see : Instance Limitations Dark Iron locations . The Ring of Law & The detention block . The main two nodes of interest here do not appear to share spawn points . Most other nodes in these 2 groups are unreachable because of the many Bloodhound patrols that cover this inner area . Note : The yellow and magenta nodes are not properly analyzed yet , and some can and will spawn at the same time . The Yellow Nodes . These nodes still need to be analyzed . The Magenta Nodes . These nodes still need to be analyzed . The Dark Iron Highway . The Dark Iron Highway is a crowded place , and an interesting gauntlet for any non stealth class . The first mobs you ' ll encounter are 5 Elite dwarves and 1 dog on each side . These bloodhounds can detect stealth , so you need to stealth past by almost hugging the dwarves . Go past by staying 1 - 2 feet away from the dwarves and the dog should ignore you . Generally the dog on the left is furthest away from the dwarves so he is easiest to get past . No improved stealth skill or distract ability required , though it never hurts to have it either . Alternatively the first 2 dogs are each solo pullable . Turn directly left and look for the green nodes on the map . If none show up then probably node # 2 has spawned , which is safe to mine . The Hall of Crafting . These are in the area behind the dark anvil after Lord Incendius ( Lord Incendius has been buffed and is now very hard to solo , but he is easy to pass ) . The Black Forge . The Dark Blue Nodes . It is a long way to reach , and there is no way to go back to the instance and reset if you go to the Molten Core entrance , but there are two possible spawn points for Dark iron here that you can mine safely . If is recommended to leave these nodes until the end of your run ( s ) so that you can mine an extra node just before smelting , then hearthing back home . To get to these nodes you will either have to fight through the chamber of the 7 Dwarves ( which if you can manage more power to you ) or travel along the fiery bottom of Blackrock Depths , as outlined in the guide How to solo Attunement . For a quick overview of the latter course , the best places to jump down are northwest from the Black Anvil ( Lord Incendius ' s chamber ) and straight down from Ambassador Flamelash after which you will need to lava - jump until you reach a safe place to stand on the north / northwest wall . Hug the wall towards the Molten Core entrance and fire - jump to get to the small island right before the Black Forge . Watch out for fireguards in the lava and be sure to bring something to mitigate fire damage . There is probably a linked third node as well , because sometimes neither # 1 or # 2 spawns . Recommended path . The fastest way to cover all nodes : Farming at Level 70 . It is possible to reach all nodes in the Magenta , Yellow , Green , Red , and Teal sections as a level 70 rogue . The dogs can still see you in stealth , but the distance is reduced . In some tunnels , you can get enough distance from their patrol patch to avoid being seen . You should be able to take on up to 5 mobs without significant risk of dying or being starved of cooldowns . Do be aware of patrols - they can cause problems if you do not account for them . Crippling poison is recommended as the humanoid mobs will try to run away and two packs of mobs can kill you : some of the mobs can put a bleed debuff on you that is not clearable with cloak of shadows , so between that and the dogs ' ability , vanish is sometimes completely neutralized . If you are willing to put in the extra 5 minutes , you can clear all of the mob packs in the teal area - the constructs have a fair chance of dropping a dark iron ore , adding to your count for the run .
