1. Introduction↑top
The Gate of the Setting Sun is the only passage between the Vale ofEternal Blossoms and the Dread Wastes. It is currently closed, in an effortto contain the Mantid army and prevent it from invading the vale. Throughout the dungeon,you will combat the Mantid assault, which climaxes in their breaking through themain gate and entering the courtyard in front of it.
The dungeon has a linear layout during which you will progress throughthe ramparts before descending to the ground level to close the gate.The dungeon features both Normal (level 89+) and Heroic(level 90) modes. There are nodifferences in mechanics between Normal and Heroic modes. The onlydifferences are increased health and damage done for all bosses and enemies.
This guide will cover all of the four boss encounters, as well as thequests and achievements that are available in the dungeon.
The level of the items you can obtain from the Gate of the SettingSun is 463, with one exception,

3. Quests↑top
There are 2 quests that can be completed within the instance. They areboth given by Bowmistress Li at the entrance of the dungeon.
The first quest is Lighting the Way. It requires you to light the flamesignal, which is located on the northernmost part of the rampart. You willbe able to access it right before fighting Commander Ri'mok, the third bossof the dungeon.
The second quest is That's a Big Bug!. It requires you to killRaigonn, the final boss of the dungeon.
Only Lighting the Way has rewards. They have an item level of 440(see loot section above).
4. Trash Mobs Before Kip'tilak↑top
On your way to Saboteur Kip'tilak, the first boss of the instance,you will fight several groups of trash mobs. While the mobs themselves donot pose any threat, you will have to be aware of the bombs that other Mantidunits, who are flying above the ramparts, will regularly drop on you. Thesebomb explode and create four damaging trails of fire that travel awayfrom the explosion. As you will see, this can become problematic when severalbombs go off at the same time.
5. Saboteur Kip'tilak↑top
The fight with Saboteur Kip'tilak is relatively easy, especially sincethe preceding trash mobs have prepared you to deal with the Mantid bombs, whichmake up the only difficulty of the encounter.
In addition to dealing melee damage to the tank, Kip'tilak will often throwexplosives (Stable Munitions) at random locations in his room.
When one of these explodes, trails of fire run through the room in eachof the cardinal directions (north, east, south, west). Similar trails offire are created by 
Sabotage, which the bosswill often cast on a random player, causing them to explode after a few seconds.
Stable Munitions are, as their name indicates, stable. They will detonateonly if hit by a trail of fire, which, as we explained above, can be the resultof another pack of Stable Munitions exploding or the resultof a player afflicted by Sabotageexploding.
Additionally, when Kip'tilak reaches 70% and 30% health, he will detonateall the Stable Munitions currently in the room with World in Flames.
The strategy for this boss is all about positioning. Each party member mustalways position themselves in such a way that there are no bombs directlynorth, east, south, or west of them. This way, they will not get hit bytrails of fire, and their Sabotage explosionswill not detonate additional bombs.
5.1. Achievement: Bomberman
Completing the 
Bomberman achievement is very straightforward.You need to get Saboteur Kip'tilak to 72 or 73% health and then hold off DPSuntil he has thrown 15 Stable Munitions around the room. During thistime, party members need to avoid detonating them with Sabotage. When you reach 15 Stable Munitions, push theboss below 70% and he will detonate all the bombs with World in Flames.
6. Striker Ga'dok↑top
Striker Ga'dok is located in the Gate Tower Watch, so just above thenorth pillar of the gate. Friendly NPCs will activate an elevator for you to getthere.
As most heroic dungeon fights, the encounter with Striker Ga'dok is notdifficult, provided that you properly pay attention to what matters. The mostimportant aspect of the fight is 
Strafing Run, which happens twice, whenGa'dok reaches 70% and 30% health. When this happens, the boss engulfs half theplatform in flames twice (first from west to east, and then from north to south).As you can see in the image on the left, the flamesseparate the platform in two and it is important that you stick with the restof your group. This will enable you to properly take care of theKrik'thik Strikers that will attack your group during the Strafing Run.
In addition to that, you need to be aware of 
Acid Bombs, which are regularlydropped by Krik'thik Disruptors. These bombs create pools of poison on theplatform's surface.
Finally, healers should pay attention to 
Impaling Strike and
Prey Time.
- Impaling Strike deals Physical damage to the tank equal to 50% of theirhealth, so they need to be topped off.
- Prey Time is a damaging DoT that the boss will regularly apply onparty members.
7. Commander Ri'mok↑top
After defeating Ga'dok, you have to use the cannons at the Gate Watch Tower tosecure the northern ramparts where you will be able to light the flame signalfor Lighting the Way. Then, you will face a few adds before being ableto fight Commander Ri'mok.
During the fight, Ri'mok has to be continuously moved up the ramp in orderto prevent him from standing in the poison pools that he creates with
Viscous Fluid. Indeed, standing in them causes him to stack a buff onhimself that increases his damage dealt and reduces his damage taken. Itstacks up to 5 times.
Other than that, you need to avoid standing in front of him as he hasa damaging frontal attack called 
Frenzied Assault.
Finally, Krik'thik Swarmers and Krik'thik Saboteurs will regularlyjoin the fight and need to be killed.
Healers need to watch out for 
Bombard, which the Saboteurs willregularly cast. This ability deals damage to all players.
8. Achievement: Conscriptinator↑top
Once Commander Ri'mok is defeated, three Krik'thik Conscripts will appearon the rampart, close to the entrance, enabling you to complete
Conscriptinator. Upon dying, they leave behind pool ofpoison that gives you a stack of Resin Residue when you step in it.You need to stack this debuff three times, by stepping in the pool ofpoison left behind by each of the three Krik'thik Conscripts.
Note that Resin Residue lasts 1 minute, so you will need tokill the second Conscript at most 1 minute after the first, and thethird at most 1 minute after the second.
Also, Resin Residue increases the damage you take from
Resin Burst, one of the abilities the Conscripts cast. Healersneed to watch our for extra damage taken as the fight againstthe Conscripts progresses.
9. Raigonn↑top
After defeating Commander Ri'mok, the Mantid will break open the Gateof the Setting Sun, giving a chance to Raigonn, the giant Kuchong, toenter the gate's courtyard. There, he will hammer the last rampart that still standsbetween the Vale of Eternal Blossoms and the Mantid armies.
This final boss encounter is a two-stage fight. During Phase One, you willhave to break Raigonn's carapace, all the while dealing with a number of adds.During Phase Two, Raigonn will fixate on random party members and you need toDPS him down.
Raigonn never needs to be tanked, but some of the adds do.
9.1. Phase One
During Phase One, you must prioritise the adds over Raigonn.
Below, you will find a list of the various types of adds you have tocontend with.
-
Krik'thik Swarm Bringers fixate on a random party member with 
Screeching Swarm,inflicting Shadow damage every second to the targeted player, as well as to playerswithin 20 yards. Killing the Swarm Bringers should be the top priority during thisfight. -
Krik'thik Protectorates come in waves of 8. They need to be tanked andAoE-ed down. When they reach 20% health, they cast 
Hive Mind, increasingthe attack speed of remaining nearby Protectorates. Therefore the tank and healershould expect a damage spike when this happens. DPS players should damage all theProtectorates evenly until they all reach 20%, before killing them one by one. -
Krik'thik Engulfers fly above and create tornados called
Engulfing Winds on the ground. These tornadoes dealproximity damage within 3 yards and should be avoided.
Raigonn should be taken care of whenever you are not busy with adds.
He keeps battering the rampart to the Vale of Eternal Blossoms by using
Battering Headbutt. He cannot be directly damaged, so you needto break his carapace by attacking his Weak SpotTo reach this weak spot, you needto use one of the launchers (as pictured on the left). Each time Raigonn uses Battering Headbutt, he throws all enemies attacking his weak spot on the ground, anddamages everyone within 10 yards of the impact. So, remember to jump offhim before the impact.
9.2. Phase Two
After his carapace has been broken, Raigonn enters Phase Two. He takesincreased damage, because of his 
Broken Carapace, and keeps using
Fixate on a random player. He does not need to betanked. Players fixated upon must drive him away from other party members becausehe regularly casts 
Stomp.
Adds will no longer be spawning, but you may have leftovers from Phase One.You may choose to finish them.
9.3. Achievement: Mantid Swarm
To complete 
Mantid Swarm achievement, you need to defeat Raigonnwithout killing any of the adds. The idea, is to use all your available cooldownsduring Phase One to push Raigonn into Phase Two with as few adds as possible.
There is a high amount of randomness associated with this achievement, assome waves of adds are a lot more difficult to deal with than others.
