Step 1: The Tunnels

 * 1) From Yanshi, run to either Issk @ 12.9S, 46.5E or Vincadi @ 12.6S 46.7E.
 * 2) * Note: Each NPC offers the same quest, however the lore is different for each. Flagging with one will prevent you from accessing the other, so be sure your whole group flags with the same NPC.
 * 3) * Tip: Soft tie to the surface portal @ 13.0S, 47.3E for convenience. If you die, you'll want an easy way to get back quickly.
 * 4) When your group is ready, everyone should hand their Harbinger Item to the NPC (either Issk or Vincadi) and then use the nearby Tunnels to the Harbinger portal to begin.
 * 5) Once inside, the dungeon is linear to the bottom (keep heading down).  The only obstacles are a series of 4 jumps that must be made.

 * 7) * Jump 2: Lava Pit - Jump into the pit and take the hallway to the North
 * 8) * Jump 3: Ice Shelf  - Shift-jump down onto the platform above the ice shelf, clear the spawn, and wait for your group.
 * 9) * Jump 4: Ice/Acid Pit Combo - Dispell, then shift Jump down onto the ice shelf and quicky run to the edge and full jump across the acid pit (land on invisible platform). The ice hurts, so be quick.
 * 10) * Jump 5: Staging Area - Shift jump down and quickly move to the south (near the portals).
 * 11) Take the Essence Chamber Portal
 * 12) Kill each of the 4 Essences, the Essence of Strife, Essence of Enchantment, Essence of Artifice and the Essence of Verdancy

 * 15) Kill the Harbinger, loot a Harbinger Arm Token, and take portal which spawns after he dies
 * 16) Talk to Issk or Vincadi for experience and 1 point into the skill.
 * 17) Hand the Harbinger Arm Token to the Emissary of Asheron for the title "Harbinger's Bane"
 * 18) Handing the Harbinger Arm Token to Ciandra gives you Shimmering Prismatic Oil.
 * 19) You can apply the Shimmering Prismatic Oil to a Diamond Shield or a Helm of the Elements to upgrade it.
 * 20) * Or, If you don' want to upgrade an item, you can give the oil back to Ciandra for 6,500,000? xp.

You give Talar the Apprentice Decanter of Essence of Artifice. Talar the Apprentice tells you, "Ah, Essence of Artifice! I can't wait to start testing this. These Essences react differently to various alchemical tests than the pure essence we collect from the Fathomless Chasm." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Enchantment for me." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Verdancy for me." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Strife for me." You give Talar the Apprentice Decanter of Essence of Enchantment. Talar the Apprentice tells you, "Ah, Essence of Enchantment! You didn't get any on you I hope. I theorize that this essence could have dangerous effects if it comes in contact with a creature. I'll have to be very careful while I'm testing this." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Verdancy for me." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Strife for me." You give Talar the Apprentice Decanter of Essence of Strife. Talar the Apprentice tells you, "Ah, Essence of Strife! War in a bottle eh? I don't know where to begin testing this. I'll have to confer with some of the Arcanum's War Magic specialists." Talar the Apprentice tells you, "You still need to retrieve a sample of the Essence of Verdancy for me." You give Talar the Apprentice Decanter of Essence of Verdancy. Talar the Apprentice gives you Prismatic Oil. Talar the Apprentice gives you An Ancient Masonry on Aerlinthe. Talar the Apprentice tells you, "Ah, Essence of Verdancy! It's a good thing this decanter is enchanted or the essence would have eaten right through it and through the floor stones and through the ground beneath. In fact I don't think it would stop until it reached its source." Talar the Apprentice tells you, "Let's see, where did I put those enchanted gloves." Talar the Apprentice tells you, "Excellent, more essence samples. These will prove invaluable in my continuing research. Let me mix your reward." Talar combines a small amount of each essence into a small vial of viscous red oil. He holds the bottle up to the light and watches as the oil clears and prismatic colors can be seen spinning in vial. Talar the Apprentice tells you, "Here you go. This oil works on the same principle of elemental energies that the Prismatic Plume uses. Apply this oil to a piece of Greater Amuli Shadow Armor and you should be able to instill it with an impressive amount of elemental protection. If you would prefer a different reward then give me back the Prismatic Oil and I'll see what I can do." Talar the Apprentice tells you, "If you wish to apply the Prismatic Oil to one of the other Greater Shadow Armor pieces you should read this report we received from an Arcanum Researcher on Aerlinthe Island. He found a buried structure there which may hold the required intermediary you need to instill the other armor sets with the Prismatic Oil."

You apply the oil to the surface of the shield. The oil hardens into a hard prismatic crystalline shell. A soft glow surrounds the shield and storms become visible in the prismatic coating.
