LDoN Raid: Miragul's Menagerie: Frozen Nightmare

Recruiter: Qileour Bahiael, Everfrost camp · Theme: Miragul's Menagerie · Portal: Everfrost Peaks

What the recruiter says

Hail: Qileour Bahiael says, 'I am busy building a strategy to take on those oddities deep under the ice here. If you need something, speak up now. I have little time for pleasantries. However, if you can rally the call of your friends perhaps you can help us with a serious [problem].'

[problem]: Qileour Bahiael says, 'It is terrible that we are losing so many faithful Wayfarers to the chaos of Miragul's Menagerie. As experienced as you are, I hesitate to burden you with this task. It would require you to venture into an extremely dangerous area in the menagerie from which you may not return. I implore you to go deep into an area known as the Frozen Nightmare. It is through there that you would be dropped into the heart of the pandemonium where we have lost our best comrades. I need you to locate and exterminate whatever is killing our people. Are you [interested]?'

[interested]: Qileour Bahiael says, 'Keep an eye out for the lost members while you're there, and always be on your toes. Miragul's oddities are as strange as they are deadly. These caves are not called the Frozen Nightmare for nothing.'

How it plays out

1. Find Durgin Skell. He is the only one of his party left alive. Ask him about the [monstrosities] and he tells you about the [bone golem], the [skeletons], the [maw], and the [sludge]. Those are your four tasks, and you can do them in any order. Hail him or ask about [progress] whenever you want a status update. Every finished task brings a zone message ("One of the four tasks has been completed.", "Two of the four tasks have been completed.", and so on).
2. The sludge. Kill the giant sludge east of Durgin's hiding place, then everything it splits into.
3. The chromatic skeletons. Four skeletons, two in each of two rooms, change color every time they fall. Once all four are red, they have to die within a few seconds of each other, or they keep getting back up.
4. The bone golem. Destroy Marrow the Broken.
5. Sharalla's remains. Hail Sharalla's warder in the maw, and starving animals rush at her body. Kill them before they ruin it. If they reach her, you see "Sharalla's remains have been irreversibly defiled by the wild animals. You have failed to protect her." The task counts as done either way.
6. Laskuth the Colossus. After "All four tasks have been completed. You should return to Durgin and inform him of your success.", hail Durgin. The cavern shakes, "A deep, thundering roar rumbles from the northeast," and Laskuth shows up at the frozen waterfall. Kill him: "Your victory has shattered the shroud of magic surrounding the dungeon's treasure"

Watch out for the Frostfoot goblins on the way. Running into their scout sets off an ambush ("It must be an ambush! An army of ice goblins are pouring forth, rushing in from every direction."). It isn't one of the four tasks, but if you let it go on too long, "You are overwhelmed by the Frostfoot horde." and the whole raid gets thrown out of the zone. Kill the two goblin leaders to end it.

Reward

Two chests appear when Laskuth falls, plus a third (a weathered barrel) if you saved Sharalla's remains from the animals.
