Dialogue
 * "The moment we have long dreaded has arrived: Dhuum is breaking free from the Hall of Judgment! Should he seize control of the Underworld, Dhuum's reign will be brutal and uncompromising, for he is the Final Death, and he does not tolerate resurrections or the undead. There is still one slim hope, a shadow of chance to hinder Dhuum's return. Grenth's seven faithful reapers will channel their energy in an attempt to force Dhuum back into dormancy. But The Ender of All is a powerful adversary, and the Reapers cannot face him alone. Protect the Reapers while they perform their grim task. At least one of the seven Reapers must survive to seal Dhuum within the Hall of Judgment.


 * Should you perish in this conflict with Dhuum, do not despair, for you spirit may still continue to the battle. Mayor Alegheri can speed you spirit's return to the Hall of Judgment, where you may rejoin the fray and assist the Reapers.


 * The fate of the Underworld depends on your success! Now you must face Dhuum. I will be here...if you return."

Walkthrough
Enter the Underworld as normal and complete all the quests the Reapers give you. When they are complete, walk towards the Hall of Judgement and accept the quest from King Frozenwind before entering the now open door of the Hall of Judgement. Upon entering, the party will encounter Dhuum. He will initially be an allied NPC, but after the entire party enters he will become hostile. At that point, the doors to the Hall will close and the party forced to fight him. At the same time, every Reaper of Grenth will appear in a large radius next to the walls of the Hall and continuously cast Dhuum's Rest, also a Dhuum's Rest bar will appear to show the progression on putting Dhuum to rest. After the Dhuum's Rest bar is finished, all Reapers will stop using Dhuum's Rest and begin to attack Dhuum, the Dhuum's Rest skill will have no effect from this point.Continue damaging Dhuum until he has 25% health and then talk to King Frozenwind for your reward.

Tips
While fighting Dhuum, note that he is unaffected by conditions and knockdowns so it may be a good idea to become a spirit if you are using a condition-dependent build such as Searing Flames or a knockdown-dependent build, as it won't be effective against him. Dhuum likes to spike single targets, bringing anti-spike skills such as Infuse Health can help to catch the quick drop of a party member's health. Note that although you can't use resurrection skills, a Scroll of Resurrection will still work so consider bringing some of those for emergency situations.

If a player dies while fighting Dhuum, they are transported to the Forgotten Vale and fall under the effect of Spirit Form, which replaces the character's skills with the following:
