Primary
In this mission, the party is trying to get into Abaddon's Mouth, the entrance to the volcano where the Door of Komalie is located. Unlocking the Door of Komalie will supposedly yield the best tool for defeating the Mursaat.

Brechnar Ironhammer will throw himself at a large group of Mursaat as you enter this mission (point A). Do not try to save him: he is supposed to die drawing away the Mursaat; trying to save him may wipe out your party. Let him go, and veer right. Once you've gone as far right as possible, you should see two groups of three Mursaat spellcasters. A group of Jade Armors and a group of Jade Bows will slowly circle around the lava pit to attack you from behind; you can either wait to take them out, or go after the Mursaat first. Either way, when you are done, follow the purple path on the map until you come to point B.

Here you will be confronted by a Mursaat Tower powered by an Ether Seal, and they are bad news for your party. While the seal remains, the tower is activated by your proximity, and will initiate an area effect that quickly drains away your energy. Additionally, the seal will cast Air Magic spells. So, not only will you not have the energy to hit the seal with spells and skills, but you will not have the energy to heal your teammates as they get clobbered with Chain Lightning and Mind Shock. When attacking a seal, you should first try to lure away its defenders to a distance where your healers and spellcasters can operate outside the tower's light radius. The seal itself is much easier to destroy once its defenders are dead.

Tip: It may be a good idea for your Warriors to bring a few adrenaline-based attacks, and not just energy-based ones.

Tip: Knockdowns do work on the seals. The round seal will collapse when it is successfully knocked down. Starting combat with interrupting spells that interrupt over time is also a useful strategy, since the seal does not move. It is not required that you destroy the seals. You can simply run past them.

Tip: Having an Elementalist cast Mark of Rodgort promptly on the seal will ensure that casters will be able to maintain decent damage dealing on the seal by simply attacking with their weapon (fire damage weapons trigger the effect of Rodgort's).

Tip: Any Rangers in the party should bring a flatbow of some kind, the range of the flatbow is longer than that of the seal's effect range.

Keep going on the purple path. You will engage various groups of Igneous Ettins, wade through a pool of lava, and pass another seal. At point C, Vizier Khilbron will appear and note (quite shrewdly) that the main entrance is too tough to tackle head-on. He advises you to take the back route into the Mursaat fortress to try and get into Abaddon's mouth. It is arguably as difficult, if not more so, to take the back route, but either an assault on the front gate or fighting your way to the back will satisfy your mission objectives. If you're taking the back route, just follow the purple path.

Tip: Having a Monk cast Light of Deliverance, makes surviving lava's burning damage much easier.

Note: It is worth noting that the back route can be more difficult than the front route, depending on party composition and party cooperation. It includes fighting the deadly and very resilient Lava Spitters, as well as having to traverse flaming pits of lava, and facing nuking Lava Imps! For some parties, the concept of pulling mobs away from the Ether Seals on the front gate is simpler than the strategies required for negotiating combat around lava pools and dealing with waves of fire AoE spells. In addition, the front gate is needed for the completion of the bonus.

If you go through the front, note that it's possible to gain access to the back route (for Skill capture or whatever your motives) by attacking the ether seal holding the west door using spell casters with ranged non-projectile spells.

Tip: A necromancer with Spiteful Spirit makes tightly packed mobs like the Lava Imps much easier. It also works well on Ether Seals.

You will engage various groups of wildlife on the Islands if you take the back route. Eventually, you will approach the Mursaat encampment to the west. Take out the groups of Jade Armors, Jade Bows and Mursaat carefully. You will be able to get to a bridge, but its end will be locked. The lever to open it is in the adjacent room (point D), guarded by a Mursaat boss. Luckily, you should be able to sneak into the room without triggering the host of nearby enemies guarding the front gate.

Pull the lever, and cross the bridge, which has a lone boss halfway across. You will finally face a group of Mursaat and then a Mursaat boss alone in the central chamber. Defeat them to win the mission.

Note: All Mursaat in the last group must be defeated to win the mission. If you want to capture a skill from the last boss, kill it first so that the mission won't end when you kill it.

Bonus
Method A: Clear out points 2 and 3. Talking to the Ancient Seer right before point 1 triggers the Eidolon to appear between points 2 and 3, so clearing the area before talking to the Ancient Seer results in Eidolon appearing by itself. Bring the Spectral Essence from the Eidolon to the Ancient Seer to get bonus.

Method B: Go to point 1 after destroying the first Ether Seal. There you will find some Ettins (with a boss) and the Seer. Speak to the Seer and it will ask you to retrieve the Spectral Essence from the Eidolon located at point 3. You will have to destroy both Ether Seals in the courtyard, which will cause the Eidolon to spawn.

Note: Parties that have completed this bonus have entered the fortress by breaking through the main gate before taking down the two seals in the courtyard. When you have destroyed all the seals, the Eidolon appears. It has been confirmed that the two seals outside the main gate and the two seals within the gate, which power the Mursaat Towers, must be destroyed in order to spawn the Eidolon.

Tip: Assaulting the main gate is fairly easy with careful luring and timing. One trick is to have a party member with a longbow shoot at a seal: this will cause the patrol guarding it to engage you. This helps you avoid any surprises from patrols. Also, it is possible to destroy only one of the seals so that the gate does not open, then take out the enemies using spells before entering.

After killing the beast, take its Spectral Essence back to the Seer. You will get the bonus, as well as a chance to infuse any parts of your armor do not yet have the benefits of infusion.
