Weakened Harbinger Quest

Quest Overview
Quest to kill the Harbinger after weakening it by cutting of its connection to the Essences of Magic.

Important:
 * The Weakened, Essenceless and Empowered Harbinger quests all share timers for the free skill point and the Harbinger Arm Token.
 * You will need one quest item to give to Issk or Vincadi to enter the Tunnels to the Harbinger. The items are all dropped randomly by certain creatures. Each item is also tied with a skill and on completion of the quest you will get one free point into that skill (see also quest XP reward).

Walkthrough

 * 1) Buy a Decanter of Nullified Essence from Beldin the Gem Dealer in Old Yanshi.  He is in a burned out building.
 * 2) Give Decanter to the nearby Stone of Yanshi.  Everyone must turn in a Decanter to be flagged to get rewards.
 * 3) 3 waves of enemies will spawn nearby, first a wave of Elementals, next Child of Acid, Child of Fire, Child of Frost and Child of Lightning, then Caustic Knight, Galvanic Knights, Incendiary Knights and Glacial Knights.
 * 4) After the enemies are all dead, the Reflection of the Harbinger will spawn.  Kill him.
 * 5) Once the Reflection of the Harbinger is dead, loot a Reflective Shard from the ground.  The shard is used for reward turn in only.  Killing the Reflection activates the Tunnels to the Harbinger portals to be the "easy" version.  They will remain like this until the Harbinger is either defeated or the quest resets.
 * 6) 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.
 * 7) 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.
 * 8) * Jump 1: Acid Pit - Full jump ahead (land on invisible platform)
 * 9) * Jump 2: Lava Pit - Jump into the pit and take the hallway to the North
 * 10) * Jump 3: Ice Shelf  - Shift-jump down onto the platform above the ice shelf, clear the spawn, and wait for your group.
 * 11) * Jump 4: Ice/Acid Pit Combo - Dispel, 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.
 * 12) * Jump 5: Staging Area - Shift jump down and quickly move off of the lava/ice floor.
 * 13) Unlike the other Harbinger quests, there are no portals after the 5th jump.  Instead, you must continue to jump down a few times until you reach the Harbinger.
 * 14) Note that because there is no portal to the Harbinger, there is no easy way to get back if you die.
 * 15) The Harbinger has a few elementals with him at the bottom.  Clear them out first before attacking the Harbinger.
 * 16) The Harbinger can be debuffed and is an elemental type, so Atlan Weapons and Isparian Weapons with Major Prismatic Stones in them work well.
 * 17) Kill the Harbinger, loot a Harbinger Arm Token, and take the portal which spawns after he dies.  You must take the portal to be flagged for rewards!
 * 18) Talk to Issk or Vincadi for 1 point in the skill related to Harbinger item turned in.
 * 19) Hand the Harbinger Arm Token to the nearby Emissary of Asheron for the title "Champion of Dereth" and the Royal Coat of Arms Stamp.
 * 20) Hand the Reflective Shard to Ciandra in Xarabydun for an experience reward.
