A Rogue in Icecrown Citadel – Festergut

As with all of my guides, this is not intended to be a strategy for the whole raid.  It is only intended for rogues and other melee dps classes.

Festergut, like Saurfang, is a very easy fight for rogues.  Specifically, this is a dps test for your raid.  Your job is generally going to be standing still going all-out on the boss.  Therefore, this guide will be fairly short.

On the pull, plant yourself right behind him and go nuts.  The fight will last no more than 5 minutes so you’ll get to use your 2-minute cooldown abilities twice.  If everything goes well in the fight, the boss won’t move at all, and neither will you.  Your raid needs to average about 5-6k dps per damage class (depending how many healers you have and what your tanks can do).

This fight has one interesting mechanic.  You’ll notice that the room is filled with a haze when you start.  Everyone takes damage from that.  Festergut will inhale some of the gas, which reduces raid damage but makes him hit harder.

Every so often there will be gas spores that spawn (two on 10-man, three on 25-man).  In about 10 seconds the spores will explode, but you don’t want to avoid themGet close to them! When they explode, you take a small amount of damage but, more importantly, you get a stack of Inoculation.  You really want that.  You should get three stacks from the first three spore spawns.

During the fight, after Festergut has inhaled all of the gas in the room, he will exhale it all at once, doing 50,000 damage to each player.  However, the damage is reduced by 25% for each stack of Inoculation you get, so if you got three stacks you only take about 12-13k damage.

The only time that you might be asked to move is to get the gas spores around.  Each spore spawns on a person.  The whole raid needs to be next to a spore when it explodes, which is 12 seconds after it spawns.  If, by chance, all spores  spawn in the melee group, then one of the players with a spore needs to run out to get to the ranged dps so they can get Inoculated.  You’ll need to set that up with your raid in advance.  Just make sure that you are near a spore when it goes off.  If the spore is on you, make sure you are close enough to the tanks so that they get the Inoculation.

Other than that one possibility, you’ll be able to stay put and do big, big dps in this fight.

One other piece of advice – Festergut can do a targeted AoE effect that makes people vomit for 6 seconds.  He only casts it on players at range, so we rogues don’t have to worry about this.  However, if there are fewer than three players at range (eight in 25-man) he may cast it on melee, which would be bad.  Make sure your raid has enough players at range, and that they are spread out so they don’t all end up puking.

The fight sounds simple, but that’s just for melee dps.  The tanks will be switching to manage a stacking debuff (so be careful with your Tricks if you use it on the tank).  Healers need to switch from raid healing to tank healing as Festergut inhales gas.  None of that affects the rogues, though.

A note about a “just in case” situation… if somehow you don’t get all three stacks of Inoculation then I’ve read that you can avoid his 50k damage explosion by using Vanish just at the instant the cast goes off.  I haven’t tried it myself, so take this advice with a grain of salt.

Festergut has a couple of attractive drops for rogues.  On 10-man, he offers Precious’s Putrid Collar for your neck slot and Plague-Soaked Leather Leggings.  There’s a slow mace, too, if you have seen any mace rogues out there.

The 25-man version has a leg slot item, also – the Gangrenous Leggings.  There is a lso a 2.6 speed fist weapon, Black Bruise.  Unfortunately, there’s really nothing else for us here.

    Vanish immunity may work on exhale (Pungent Blight), but so does feint so no rogue should die from this damage. I managed to survive with only one stack of spore debuff thanks to feint.

    Thanks for writing that nice guide!

    And yeah I’ve been surviving thro it just fine with Feint… I love feint.
    But… Vanish immunity exists? 😮

    I thought they only put that on the PTRs but that it never went live.

    MegaMick: yes vanish immunity exists and is something other than what they put on PTR recently. It’s not in the ability tooltip, but it works. For example you can vanish Loken nova, Emalon nova, Putricide experiments explosions (though it’s risky) and Mark of the Fallen Champion on Deathbringer Saurfang encounter. Basically you vanish right before the cast finishes (low latency helps), but I had success vanishing Emalon nova about 1 second before he finished casting. If it works (and in the above cases it worked for me reliably, every time I used it), you completely avoid damage and nasty effects like knockback.

    The one time vanish immunity failed for me was on Assembly of Iron overload (nova like) ability. Perhaps I was just late, but never tried it again.

      What you do on Putricide when using Vanish during the stun is not vanish immunity and it’s not risky at all as of recent change to Tear Gas mechanics.

      Vanish immunity requires, by definition, to catch that elusive moment when a harmful spell has already went off, but has not landed yet.
      On Putricide you just hit Vanish during rather continuous (2.5 sec) cast and enjoy. Since all other players are not immune to damage now and Vanish removes you from aggro table, you are free go nuts on Putricide without a slightest possibility to pull aggro. Whoever was on top of aggro list at the beginning of the stun will stay there by its end.

        I wrote about Putricide experiments explosions, not tear gas. It’s risky as when you avoid green experiment explosion and its knockback, it may pick you as its next target and you’ll die as you’re the only player in range. I normally use it on tear gas tough and yep there’s no problem with that.

    One very important hint for melee classes that get the spores – if you’re at the back of the boss, then your tank will not get the debuff. If it’s on your tank (and yes we had that happen a few times, the encounter prefers other targets than the main threat one but it still can and does happen) – you won’t get the debuff in the back of the boss.

    If your tank gets it, move to the middle of the boss’ hitbox. If you get it, move to the middle of the boss’ hitbox. If you’re a healer and you’re told to stand with the melees, just stand in the middle of the boss’ hitbox all the time so you don’t have to move at all.

    It’s safe, he doesn’t cleave or anything. And you’ll make your tanks and/or raid leaders very happy.

    > The fight will last no more than 5 minutes so you’ll get to use your 2-minute cooldown abilities twice.

    I assume there’s a typo somewhere, as during a 5-minute fight you are to use 2-minute CD abilities three times, and 3-minute CD abilities only twice.

    But, actually, my bad.
    You were talking about 10 man and the fight may not last as long as 5 minutes on 10 man difficulty. If the same people are in there that are able to do it in 5 minutes on 25 man, expect it to be over in about 3.5 minutes.

    It’s a maximum of 3 times for 2-minute CD abilities.
    Hope my crankiness will be forgiven.

    Yep, 2-min CD get used three times in the fight. Fixed that error. Thanks.

    Does Cloak of Shadows work on any of the things where you are talking about using a vanish immunity? I’ve cloaked out of plenty novas and similar, and did this fight for the first time in 10-man last night and didn’t know if cloak would work on any of the AoE.
