Hints for defeating Duncan the Black

 * Now that Duncan's Defense deals back damage even from such skills as Pain Inverter, Backfire, Mistrust, Guilt, and Empathy, it is no longer advisable to attack him in this manner. (In the past, these skills were not affected by Duncan's Defense, and were therefore very effective.)
 * All forms of health degeneration can help with getting Duncan's health down. He has no defense against Life Transfer, Life Siphon, burning, etc.
 * 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. Spirits of Recuperation and Disenchantment should be considered primary targets, but as long as one is swapping spirits, one may as well swap all of them.
 * Consider using Consume Soul to destroy these spirits instantly.
 * Players more commonly use Swap. If two party members bring swap, the process is very quick and you can remove all the spirits to a safe spot where they can affect neither Duncan nor you.
 * Using Recall also helps when swapping the spirits near Duncan; this way you avoid being spiked by Duncan's Channeling Magic.
 * Another method to defeat Duncan is to let a party member die near him and have a Necromancer spam Signet of Sorrow on him, but remember that the Necromancer will take damage from Duncan's Defense.
 * Many more pop up touchers are added in Hard Mode and can be deadly.
 * It's good to use his tactics against him, so using Gaze from Beyond and Channeled Strike against him is a good way to take him down quick and easy, do make sure though that you have some defense to go against Duncan's Defense
 * As of the June 18th 2009 update, it is possible and extremely easy to use signet of binding, summon spirits, and spiritleech aura to steal Duncan's spirits and use them against him. Spiritleech aura allows the spirits to bypass Duncan's defense so that they do not die, and it increases their DPS considerably, as they often do not use their attack skills, but instead use an attack that does 6-8 damage on average. Simply summon the spirits close to Duncan, then summon them to a location a little more than longbow range away. The spirits will continue to attack him at this distance, and the Spirits' long attack range allows them to attack Duncan without him moving, allowing them to quickly kill him.
