Icebound Frostbrood Vanquisher

Reward of the achievement Glory of the Icecrown Raider (25 player): seventeen achievements in the Icecrown Citadel raid in 25-player mode. Four are the Heroic clears of its wings (Storming the Citadel, The Plagueworks, The Crimson Hall, The Frostwing Halls: eleven bosses, the Lich King not among them); thirteen are special achievements on any 25-player difficulty, one on each of eleven encounters and two on the Lich King. One of them, Once Bitten, Twice Shy, takes two kills of Blood-Queen Lana'thel, so two visits. The mount is learned the moment the last one is earned; nothing is mailed.

Inside Icecrown Citadel, a raid (25 player; Heroic for the four wings, Normal or Heroic for the rest)

Time there about 45 min a visit

Guides Wowhead: Glory of the Icecrown Raider · wow.gg: Reins of the Icebound Frostbrood Vanquisher · Wowhead: Glory of the Icecrown Raider (25 player), achievement page (the comment of February 2015 goes through every achievement for one player)

• Two kills of Blood-Queen Lana'thel in 25-player mode, in two different weeks or on two characters of the account: Once Bitten, Twice Shy asks for one kill as a vampire (wait about 15 seconds for her bite, which gives Essence of the Blood Queen, then kill her) and one without becoming one (kill her before the bite, but not with the opening blow), and a character can kill her once a week. The other sixteen achievements fit into the first visit, with the raid set to 25-player Heroic for the eleven bosses of the four wings · about 1.25 h over 7 days

In all: about 1.3 h of play, spread over 7 days, starting from nothing.

/way is for the TomTom addon. Travel times are estimates: flying at 55 yards a second in a straight line and 30 seconds for a portal. A star marks a portal that needs a quest or other unlock done first.

Wowhead's tooltip for the achievement (as read in 2026) lists the seventeen criteria and marks progress as account-wide; the wiki has the same list. The 25-player meta has one achievement more than the 10-player one, Neck-Deep in Vile.

Setting the raid difficulty to Mythic makes Icecrown Citadel Normal; it has to be set to Heroic (replies of 2021). The Lich King does not have to be killed on Heroic.

The thirteen special achievements, in the game's wording where it was read (wiki, Wowhead's guide) and from wow.gg otherwise:

• Boned (Lord Marrowgar): no raid member stays impaled for more than 8 seconds
• Full House (Lady Deathwhisper): at least five different types of Cultists active when she dies
• I'm on a Boat (Gunship Battle): no raid member visits the enemy ship more than once
• I've Gone and Made a Mess (Deathbringer Saurfang): dead before Mark of the Fallen Champion is cast five times
• Dances with Oozes (Rotface): no Big Ooze casts Unstable Ooze Explosion
• Flu Shot Shortage (Festergut): nobody reaches three stacks of Inoculated
• Nausea, Heartburn, Indigestion... (Professor Putricide): without using Regurgitated Ooze on the Abomination
• The Orb Whisperer (Blood Prince Council): nobody takes more than 25,000 spell damage in one hit
• Once Bitten, Twice Shy (Blood-Queen Lana'thel): once as a vampire and again without becoming one
• Portal Jockey (Valithria Dreamwalker): enter every portal she spawns before healing her to full health
• All You Can Eat (Sindragosa): nobody above 5 stacks of Mystic Buffet
• Been Waiting a Long Time for This (the Lich King): let Necrotic Plague stack to 30 before defeating him
• Neck-Deep in Vile (the Lich King): kill every Vile Spirit before it explodes

Most are a matter of the boss dying quickly. The ones that are not, from Wowhead's comments, follow.

Once Bitten, Twice Shy: a player fighting her without others is bitten after about 15 seconds, and having Essence of the Blood Queen at her death counts as the vampire kill (comments of 2014, 2018 and 2021). For the other half she has to die before that, but a kill with the very first blow gives no credit: walk into her or open with a weak or damage-free ability, wait a few seconds, then kill (comments of 2017, 2020, 2024 and 2025). The order of the two does not matter (replies of 2022 and 2023). Older comments that both halves must be done by one character are out of date since progress became account-wide (wiki: patch 11.0.0; a 2024 comment and a 2026 reply did it with two characters).

Portal Jockey: the achievement also comes when she is healed to full before she spawns any portal (wiki; a 2015 comment, edited 2020; two comments of 2021, both of which switched to a healing class for it). Because that route is open to one player, no player count is given here. Once portals are up it is another matter: eight at a time in 25-player mode, with one player to a portal and all of them to be entered (Wowhead's guide), so it would take eight. A 2015 comment says the fight reset when a lone player went into one. wow.gg suggests bandages for characters without healing spells and says to do it on Normal.

Full House: do no damage to Lady Deathwhisper at the pull, so that she keeps her mana barrier and goes on calling and changing Cultists (a 2021 comment). The 2015 comment names the five, Cult Fanatic, Deformed Fanatic, Reanimated Fanatic, Cult Adherent and Reanimated Adherent, and warns against area damage. On Normal the Cultists stop coming once the barrier is gone (Wowhead's guide).

Been Waiting a Long Time for This: the plague only exists in the first phase, above 70% of the Lich King's health. It jumps to a target within 10 yards when it runs out and gains a stack when its carrier dies, and the 30 need not be on one target (Wowhead's guide; the 2015 comment). wow.gg calls it the hardest of the list for one player.

Neck-Deep in Vile: a 2015 comment says that a player fighting him alone met no Vile Spirits and was given it all the same.

The mount is learned automatically (wiki); comments of 2012 and 2013 found it in the mount list with no mail.

The entrance coordinates are from the game's own table of instance entrances; wow.gg gives 53.8, 87.1. The time on the spot is an estimate for the first visit with its waits (the Cultists, the plague, the gunship); the second visit goes only as far as the Blood-Queen.

Guides: Wowhead's is a player's guide of 2012 (last modified 2022) written for a full raid of the time, with the mechanics of every encounter and maps of the way through. wow.gg's (updated 2026) is current but short, speaks of the level 80 cap, and contradicts itself on I'm on a Boat. Wowhead shows the meta as attained by 58% of profiles.

Confidence in this entry: medium. Looked up in 2026.
