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 can move his spirits to a much more manageable position. You can also remove the Recuperation buff he receives from them.


 * 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 spamming Signet of Sorrow on him.
