Hints for defeating Duncan the Black

 * The safest way to defeat Duncan is to let a Spoil Victor Necromancer or Mesmer with Backfire, Mistrust, Guilt, and Empathy under Mantra of Recovery stand on the lower floor besides the stairs, in the corner formed by the upper floor. Neither Duncan nor the spirits he summons will hit that player there, but Protective Spirit must still be kept up on that player at all times to prevent an instant kill from Duncan's Channeling Magic spells.


 * All forms of health degeneration work can help with getting Duncan's health down too. That player keeps up the damage hexes on Duncan, who will attack and cast spells all the time. Duncan will not hit with attacks but still take damage from the hexes.


 * A player with Swap, Gaze of Fury or Unnatural Signet can move his spirits to a much more manageable position or destroy them as necessary. Consider the spirits of Recuperation as your primary targets.


 * Consider using Pain Inverter if you're spamming a damage skill on him, it will do a free 80 damage back to him.


 * Another Method to defeat him is to let a party member die near him and have a Necromancer spam Signet of Sorrow on him.

Hard Mode

 * Lightbringer rank and Lightbringer's Gaze doesn't work, and foes with strong protection/ enchantments render traditional fire nuke inefficient.
 * A lot more pop up touchers were added in hard mode and can be deadly.
 * 2 more groups of spirits are summoned when you fight Duncan. Each group includes 2 disenchantment and you cannot avoid facing at least 1 of this group.
 * Use Consume Soul to destroy these spirits instantly, especially the spirit of disenchantment.
