Icecrown Citadel 10m: Festergut: Overview

  • The fifth boss in Icecrown Citadel is Festergut and is located in the Plagueworks wing.
  • Before aggro'ing Festergut, you may want to lay out where everyone is going to stand. I'll explain why later in the guide, but it's a good idea to have atleast 8-10 yards between each range. Range should spread out in a semi-circle around the boss. Also, make sure to buff some sort of shadow resistance as well.
  • This fight is fairly simple but to beat the 5 minute enrage timer and have a smooth kill all three player types need to be decent. Dps needs to be high to beat the enrage timer, tanks need to be geared to withstand fast 25k-ish blows, and healers need to be nimble by shifting heals from the raid to the tank accordingly.
  • Raid composition should consist of 2 tanks, 2-3 healers depending on how good your dps is, and atleast 3-4 range.
  • Festergut should be tanked in the center. Melee and healers should stack behind Festergut and 3-4 range, atleast 8-10 yards from each other, spread in a semi-circle around him.

Icecrown Citadel 10m: Festergut Encounter

  • The first thing you'll notice is Festergut will cast a debuff on the tank called Gastric Bloat. The debuff stacks and increase the tank's damage. If it reaches 10 stacks it will cause a Gastric Explosion immediately kill the tank as well as causing roughly 30k damage to all players within 10 yards. Basically, expect a wipe if this ever happens. Therefore it's important the second tank taunts off the first tank around 8 stacks. You can wait till the 9th stack but it's really too risky. Since the first tank will be doing increased damage it'll be difficult for the second tank to easily pick up. Therefore, it's a good idea to use Hand of Salvation on the tank as well as have them switch to a non-threat increased form such as blood presence for DKs, battle stance for warriors, take off Righteous Fury for paladins, and cat form for druids. If they still pull aggro and hit 9 stacks, have them completely back off for a bit.
  • Throughout the fight Festergut will cast Vile Gas on a random range. The damage is around 5k every 2 seconds for 6 seconds, so healers will need to be paying attention to this and immediately heal them. The Vile Gas also prevents the target from doing anything for the 6 seconds, which is why it's smart to not have healers standing with range. Paladins can Divine Shield, Mages can Iceblock, and Humans can racial out of it. PvP trinkets can also be used. Vile Gas finally causes AoE vomiting and is why range needs to be 8-10 yards from each other. Melee and healers stacking on or behind Festergut will not receive Vile Gas as long as enough range are alive away from the boss. Think Vezax.
  • Festergut will also inflict two random targets with a Gas Spore. The two spores should be split between range and melee. All players need to be within 5 yards of the spore and they'll have 12 seconds to get near the spore. The Gas Spore applies a 25% resistance to blight and stacks up to 3 times. Being hit by both spores at the same time won't add an extra stack but will cause twice the damage so make sure both spores aren't on top of each other. Make sure range spreads back out quickly after the spore explodes. If two are cast on melee or range, make sure one covers the rest of the raid. A good time to pop Bloodlust or Heroism is after the third spore when the raid can use it the most. Dps isn't moving much and healers are stressed with increased damage from boss on tanks.
  • Every 30 seconds or so Festergut will cast Inhale Blight and suck up a bit Gaseous Blight from the room gaining a buff that increases his attack speed and physical damage done by 30%. It stacks up to three times and therefore eventually will increase his damage by 90%. Healers should progressively change their focus of healing from the raid to tanks while the damage increases.
  • Around 30 seconds after the third stack is applied he'll exhale the gas by casting Pungent Blight which will deal 43k-ish damage to all raiders. This is why everyone must have 2-3 stacks of Inoculated from the spores. A mage can Iceblock and a Paladin can Divine Shield to avoid all damage if they missed a Inoculate stack.
