Hints for defeating Duncan the Black

 * Now that Duncan's Defense deals back damage even from such skills as Pain Inverter, Backfire, Mistrust, 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 or Gaze of Fury 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.
 * A Spirit-Spammer can easily kill Duncan all alone. Swap all of his spirits away. Then place your spirits upstairs inside attack-range, but outside of Duncan´s aggro-range and make them attack Duncan. Duncan will take damage, but will not move or cast any spells. Heal summoned spirits with Summon Spirits to lower the effect of Duncan's Defense and re-summon spirits as fast as possible. Killing duncan takes about 5-10 minutes with this method. It is recommended not to use Painful Bond in this setting as this damage is thrown back on the caster and casting the spell will aggro Duncan.
