Walkthrough
Speak to Gron Fierceclaw to initiate the quest and enter the cathedral.

Throughout this quest, you will find Charr Sentries, who use the monster skill Flame Call to summon Charr Hunter Beasts. The hunter beasts are fire elementalists who can deal large amounts of AoE damage, so killing the sentry quickly or interrupting Flame Call is recommended to avoid dealing with the hunter beasts.

You will also find Charr Prison Guards, warrior bosses who drop Prison Keys, which you need to open the Charr Prison Locks. Prison guards can be rather dangerous while they have Infernal Rage active, but this can be handled either by ending the stance or using a variety of anti-melee skills.

Charr Dominators carry Resurrection Chant and aren't shy about spamming it. It can be essential to target them first, even before healers, especially when a group has multiple dominators.

Level 1
Fight through this room and the large hall until you find the first Charr Prison Guard in the northeast. While you can sneak past several groups to get to the prison guard, when aggroed, the guard will run through the other groups and try to get you to chase through them, aggroing them all. Past the locked door behind him, you will see a group of Charr spellcasters, who run away as you approach. Do not chase them, as a group of Charr Axemasters and Charr Seekers will run up from behind them. After killing all the Charr in the room and rescuing Seer Fiercereign, head back through the large hall and through the left exit to find the portal to the next level.

Level 2
The first cavern on this level is relatively crowded, so pull mobs carefully to avoid being overwhelmed. After rescuing Cowl Fiercetongue, two gates will open off of the main chamber, one to the north and one to the east. Both lead to the same place, and while the eastern path is shorter, the northern path allows for easier aggro management at the point where they meet.

The final room of this level is a cavern populated by spiders, with an open portal to the next level past the boss Jadam Spearspinner. Rushing past them isn't really an option, as they can cripple you with Snaring Web. Also, for every visible spider, at least two more will pop up, and when you attack Jadam, a large group of lower-level Spiders will spawn to the south. The safest tactic is to carefully clear the room up to Jadam, then run past her and the remaining two spiders to the portal.

Level 3
The second chamber contains a number of nearby groups, much like the first chamber of the previous floor. In the middle of this room is Roan Fierceheart, the final member of Pyre's warband. Follow the path past a couple more prison guards until you enter the cathedral itself. The third prison guard on this floor will run away when initially aggroed, and try to drag you through two pop up groups of Magma Blisters, so it may be best to just let the guard run away.

The main chamber contains the end boss, Flamemaster Maultooth, as well as many groups of two or three Charr. Killing Maultooth ends the mission, but coming near him causes the various other groups of Charr to rush into the room, as and also causes two powerful Charr Effigies to pop up. You can try to quickly rush in and kill Maultooth, but may get overwhelmed by the other Charr. It's much safer to clear the other groups of Charr first, before Maultooth calls them all in.

Even after the various Charr groups rush in to help Flamemaster Maultooth, they will remain unlinked and can be pulled apart if needed. Charr Effigies are not linked to any other Charr. You can clear as much as you think necessary before going after Maultooth and trying to finish him quickly. After Maultooth is dead, a cutscene will play, and the party will be returned to Doomlore Shrine.

Hard mode
It's probably best to clear the room with the first prison guard before aggroing it, as this ensures that you won't have to fight another group while fighting the prison guard's group.

Early on the second floor, there are two groups of three Charr each that wander, then a stationary group of five Charr that includes a prison guard, a group of six Charr that wanders in small circles around the prison guard's group, and two other unlinked Charr standing there. It can be necessary to pull groups far apart to prevent a healer from another group from stepping up to heal and bringing its whole group into combat. This can be awkward at times, as your Charr allies aren't always inclined to follow you away from the mobs as you pull, so you may have to simply let them die at times in order to get a proper pull.

You can probably take on the first two groups on the second floor simultaneously, but the prison guard's group and the group of six that wanders near it should be taken separately. The other group will chase you much further than the guard's group, and as such, should be pulled first. If you can't aggro one group without the other, then aggro them both and run far away. The guard's group will turn back, leaving you with only the other group still following you.

At the north corner of the second floor, there is a group of three Charr and another group of six. Both have healers, and the group of six is all casters. The group of six can be a handful by itself, as it sometimes contains as many as three dominators who can and will resurrect their allies, so it is critical to separate the two groups. This may require pulling one group a lot further than you think is necessary before attacking, to prevent the other group from following to heal the first group. Immediately after this is another group of three Charr that wanders the same area as a group of six, and these two groups should also be pulled apart, but these are easier to clear, as they have no resurrection skills.

In the spider room, clear as far as you can without aggroing Jadam Spearspinner, and then try to run past to reach the third floor. Note that your Charr allies don't understand that you're trying not to aggro the boss, so they may well run ahead of you and aggro it even if your entire party stays out of aggro range. Flag your heroes with you as you try to run past, as otherwise, they'll stop to fight and be out of range to help if you die, leading to a wipe.

The twenty or so spiders that flood the room upon aggroing Jadam are all level 24, mostly linked to each other, and spam Barrage. If you don't make it past Jadam the first time you try, you'll have to clear these spiders to move on. Area of effect anti-martial weapon skills help immensely. You can also try to use the ramp down into the room to obstruct their shots while your party kills them with line of sight ignoring spells.

Trying to quickly kill Flamemaster Maultooth before clearing other nearby Charr probably isn't the best idea but can be done if your whole party attacks him in hard mode. Regardless, the end of the mission is pretty easy if you pull and clear the various Charr groups separately.

 * The quest is probably a reference to the book and television mini series Band of Brothers, which in turn comes from a speech delivered by Henry V of England before the Battle of Agincourt in William Shakespeare's Henry V; Act IV, Scene 3.
