You need to have completed the Greenmist HQ Timeline to open the Chest with Recipe for "Greenmist Design Pattern"
Note:when you finish the Signature quest line once (including sufficient faction standing with Nye'Caelona) you can buy the The Essential Kunark Guide for 100p from Sarya Val'Sara at ( -231, 91, -241 ) Copy/waypoint -231, 91, -241 and skip the Heritage Quest! But the Greenmist proc will not function for your alt until the Heritage quest is complete.
You need to be at least a level 2 Artisan to craft the weapon
Steps[]
Enter Crypt of Dalnir: Baron's Workshop (Solo) ( 785, -129, -586 ) Copy/waypoint 784.81, -128.84, -585.71. (NOTE - if you are already 120, you MUST do this mentored or Chrono'd down to 100. The sword & shield fight requires a chest drop to unlock the door, and will not drop if they're grey)
Obtain a weapon to prove Rile is Cazic-Thule's Chosen.
Upon Entering the zone, click the right statue on the dais, to open the door on the right side.
In the second hallway between chambers, there are two niches recessed into the wall on the right. They both contain Crypt Stalker spiders mobs, and a casket. In one of the caskets there is An Obulus wizard's mirror : You MUST obtain the mirror from that coffin after defeating all the Crypt Stalker spiders , else zone is just a [Heroic] instance, Dalnir has no dialog. ( -144, 31, 29 ) Copy/waypoint -144, 31, 29 In the other crypt, kill all the spiders and at the end of a mini-ring event, the coffin will open and the venomous queen will attack. You also need to break all jars, as one of them will drop a key needed to open doors later. To break-in to the crypt behind each niche, climb up to the alcove, target, and attack the wall. The mirror spawned inside the coffin itself for me. Be sure to break all the urns to open those as well.
Need to kill Tootooz the Cryptomaniac for the walls to be clickable / killable
Hail Haggle Baron Dalnir to show him the mirror, then hail him again for conversation. He then attacks you; kill him. You are awarded Dalnir's Work chest Key
Note: You can open both doors before killing Dalnir and pick up all the items *except* the recipe. You need Dalnir's Workchest Key to open the chest with the Greenmist Design Pattern.
Pick up the following, crafting components found in random places within each room:
