The Underdark isn't a traditional campaign like most of the others. There are no dailies associated with the Underdark, and campaign progression is based on a single currency that you'll be collecting from several sources as you progress through the rest of the game. You get Faerzress from completing any Demonic Heroic Encounter scattered throughout the game, including in the Icewind Dale campaign and the Tyrrany of Dragons campaign. You will also collect Faerzress from completing the skirmishes for the achievements.. You will need to do at least ten days of progress within the campaign to unlock all the achievements, but because of the ease, you should also collect the rest of the boons. After you complete the introduction, all you'll need to worry about is remembering to click 'Process Faerzress' each day.
There are three queues to focus on for the achievements: Prophecy of Madness, Throne of the Dwarven Gods, and Demogorgon. If you do the Random Daily Skirmish, you will likely encounter one of the first two, while the third is considered a Trial. You must complete the campaign task 'Unlock Demogorgon (Master)' for an achievement.
Begin by completing the introduction quests, chapter by chapter, to unlock the Underdark campaign. There are no achievements to worry about within the quests, just progress until it allows you to access the campaign window and begin processing Faerzress.
Daily Routine - Underdark
- Collect rewards from Process Faerzress and restart the task at the cost of 200 Faerzress.
Daily Currency Totals
- Up to 100 depending on medal from each Prophecy of Madness or Throne of the Dwarven God skirmish
- Up to 150 depending on medal for each Demogorgon Fight
- Various Demonic Heroic Encounters scattered around Neverwinter.
There's really no need to worry about specifically getting Faerzress, you're going to get plenty from doing the achievements related to Underdark and from doing other campaigns.
Prophecy of Madness
Prophecy of Madness is one of the two skirmishes you will need to complete. This is a rating based skirmish that gives a medal, bronze, silver, or gold, depending on how well you do in each phase of the skirmish. There are two variants to this skirmish, one of which is chosen at random when you queue into it. You will need to obtain a gold medal once for each variant. The third achievement requires you complete the skirmish by defeating the main boss twenty-five times, so you have plenty of opportunities overall to get the two gold medals you need. Don't give up if you get silver on the first two phases, a gold on the third phase can still get you a gold medal overall. After the two gold medal achievements are achieved, killing Balor is all that matters. Obviously, the better your group and the higher your Item Level, the better you'll do. While doing the skirmish twenty-five times, for whatever reason if you haven't gotten a gold on both variants, you can gather a group of five and queue privately. That way, you can keep backing out and queuing in till you get the variant you need.
You can check your progress by going to Journal ---> Achievements ---> Slayer ---> Balors' Bane. When you've defeated the final boss, Balor, twenty-five times, you will receive the achievement:
Protect the Prophecy
The first phase of this variant requires you kill as many demons as you can. There are four tears in the arena, one East, one West, and two South. Getting gold on this phase can be difficult, especially with a random group, so getting a mid to high silver is still acceptable. Ideally, you want to have your best DPS to take both south portals. If they're strong enough, they can alternate back and forth between both tears killing each group that spawns, while the rest of the group can split up and take the other two tears. The more groups you kill, the better you do. If you find yourself dazed, you'll find blue circles around the room that you can run into and clear the daze.
The second phase of this variant is much the same as the first phase. The enemies are stronger, but still come out of the tears. Now, the demons start dropping essence randomly when they're killed. To get gold, you must deliver as many essence to the four wards around the room as possible. There's no limit to how many essence you can carry at a time, so don't try to deliver the essence one at a time. Stock up first, then go to whatever ward is lowest. The wards will decline very slowly, so a full ward won't stay full. Getting a high silver on this phase is also acceptable.
The third phase is all about killing the Balor boss as fast as you possibly can. This is the phase that will carry your overall medal, so getting as best a gold as you can is crucial. The boss can daze you as well, so be aware of the nearest well to clear it. After the Balor is defeated, your final result will pop up and if you've achieved Gold, you'll get an achievement.
The first phase of this variant involves closing several abyssal tears throughout the arena. When you close a tear, a group of enemies spawn and you have to defeat them to officially make progress. Getting a gold in this phase, as well as the other phases, entirely depends on how many and how fast you kill. Usually the group will split and go to either side. To avoid too much running around between tears, it's best to stick to either the East or the West side of the map. Just the same as the other variant, getting a mid to high silver is okay in this phase as long as you get gold on the final phase.
This phase is exactly like phase 1, the only difference between the tears now vary in size, with larger tears spawning stronger enemies. This is all about killing as fast and as many as you can.
The third phase is all about killing the Balor boss as fast as you possibly can. Similar to Phase 3 of the other variant, a good Gold in this phase can carry silvers in the other two for an overall completion of Gold and the achievement.
(Don't ask why Neverwinter made the achievement for this variant named Protector of the Prophecy while naming the other variant Protect the Prophecy. Nobody knows. Nobody.)
Throne of the Dwarven Gods
Throne of the Dwarven Gods is the second skirmish you will need to complete. The format is the same as Prophecy of Madness. You will need to get a gold medal on each of two variants of the skirmish, and then complete the skirmish a total of twenty-five times. Doing well in this skirmish is almost entirely based on knowledge of mechanics. Regardless of variant, there is one important mechanic to know. DO NOT KILL THE THOON HULKS. If there is one thing that will make you universally hated by your group in Neverwinter, it's killing the Hulks in this skirmish. You must hit the Hulks a little to trigger their charge attack, and then move to position yourself so they charge the direction you need. Usually, if that mechanic is done correctly, getting a gold medal in skirmish in general is easy. While doing the skirmish twenty-five times, for whatever reason if you haven't gotten a gold on both variants, you can gather a group of five and queue privately. That way, you can keep backing out and queuing in till you get the variant you need.
You can check your progress by going to Journal ---> Achievements ---> Slayer ---> Flayer Slayer. When you've defeated the final boss, Illithilich, twenty-five times, you will receive the achievement:
Corruption of the Throne
The first phase of this variant requires you defend two clerics near the psionic bubble. Waves of enemies will spawn, including Bone Golems, and try to attack the clerics. Don't stray too far from the clerics, and just kill everything that spawns as fast as possible. Keep going until the timer runs out.
The second phase will start spawning Thoon Hulks, and have a health bar for the shield. You must hit the Thoon Hulk once to aggravate it, and after a little while it will randomly choose a player. That player must stand next to the shield so the Hulk runs directly into the shield, damaging it. While this is happening people will still be attacking the clerics, but getting the Hulks to destroy the shield as fast as possible is the priority.
Right after Phase 2 ends, everyone will gather at the throne, where the Illithilich will spawn. At this point, all you do is kill the Illithilich as fast as you can. This is the most important phase to get a gold medal on, as a gold here can carry any silvers you might have gotten on previous phases.
Mind Flayer Infiltration
The first phase of this variant includes the Thoon Hulks. There will be four gates within the room, each with a health bar. You must hit the Thoon Hulk once to aggravate it, and direct the charge towards one of the gates. It takes three Hulks to destroy a gate. Try to spread out so you don't waste a Hulk on a gate that's already down.
Groups of enemies will start spawning around the room. There are four spawn points, one in front of each gate, where enemies will spawn. Keep killing the enemies as they spawn until the timer runs out.
Once more, the Illithilich boss will spawn at the throne. Kill him as fast as possible. Getting a gold on this phase can help carry any silvers you might have gotten in the previous phase.
Demogorgon is a 10 person trial that can be done once the appropriate item level is reached. Unlike the two skirmishes, you only need to get a gold medal once for the achievement, which is fairly common even in random groups given how the game is setup now. The fight has three phases to it, and like the others a gold medal on the third phase can heavily carry the two other phases.
The first phase involves the group typically splitting up and going around closing tears. When you try to close a tear, it will spawn a group of demons, and you need to kill the demons to progress. The larger the tear, the harder the enemies are that spawn from it. At this time, Demogorgon can not be hurt, so typically a tank will pull him off to the side and hold him away from people. If you find yourself dazed, seek out a mind well, which are the blue glowing circles scattered around the map. You have a limited amount of time to close tears, and the more tears you close, the better you do.
After a cutscene, you can move into the arena again. There will be a large boss, Goristro, who will be roughly in the middle of the map. To gold medal this phase, you need to kill Goristro. Every now and then, he will attempt to charge at someone, similar to the Thoon Hulks from earlier. Ideally, whoever he is charging at wants to aim him towards a yellow glowing portal along the walls, which will do additional damage to Goristro. In practice, especially with random groups, this usually doesn't happen. Most groups just stay where they are and continue damaging Goristro instead of worrying too much about it. Occasionally you will be told to Seek Shelter within a Sanity Well. If you want to stay alive, quickly run and stay within one of the blue circle until the message clears. Otherwise you'll be hit for a considerable amount of damage. A lot of times you'll see tanks hold Goristro near one of the wells to give people an easier time avoiding the damage. Kill Goristro and get a gold.
After another cutscene, you get back into the arena and see Demogorgon at the far end. This phase is entirely about killing him. He has less health than Goristro, but does more damage, as well as dazes and repeats the mind sanity mechanic from phase 2. Kill him as fast as you can to get a gold.
Demogorgon (Master) (Referred to in game as EDemo) has the same mechanics as regular Demogorgon. The main difference is that everything hits harder and has more health. To enter this version of Demogorgon, you must complete the campaign task 'Unlock Demogorgon (Master)' located in the Underdark campaign. While you may queue with randoms and attempt to complete it, it's best to organize a group of guild members or in a session, or join someone advertising in the Looking for Group channel in Protector's Enclave. Once you get a gold medal, you'll get the achievement.
