Quest to kill the Harbinger after weakening it by cutting of its connection to the Essences of Magic. * 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). * The Weakened, Essenceless and Empowered Harbinger quests all share timers for the free skill point and the Harbinger Arm Token.
